• An HTML 4.01-compliant Web Browser (such as Internet Explorer 5.5 or later or Netscape 8.0 or later) with JavaScript enabled

Key Features and Benefits

• Flexible storage capacity—The storage system supports up to four 3.5" SATA-I hard disks, with a capacity of 80–500 GB each. You can start with just one and add more as your needs grow.

• Built-in data protection—In addition to a linear disk configuration in which all the disks are treated as independent entities, the storage system supports several different types of RAIDs (redundant arrays of independent disks). This means that you can take advantage of the build-in data protection and data duplication offered by advanced RAID levels. If your storage system has multiple hard disks and one fails, you won’t lose important data. For more information, refer to "Disk Configurations," beginning on page 107.

Getting Started

Getting started with your storage system involves the following general steps:

1. Install your storage system.

This process involves installing both the hardware and software components of your storage system and specifying the initial configuration.

For step-by-step instructions for this process, see “Installing Your Storage System”.

2. After installation is complete and the storage system restarts, start the Web User Interface and log in.

For more information about this step, see “Accessing the Web User Interface” on page 24.

3. Add users.

If you want to control access to the shared folders, or if the users in your network use Linux or Macs that don’t use OS X, you must create a list of users.

For more information about this step, see “Adding Users” on page 30.

4. Create shared folders.

By default, the storage system includes a shared folder named public, which all Windows and Mac OS X users can access. However, you might want to create other shared folders as well. For example, in an office environment, you might want to create a shared folder for company policies that everyone can view, and separate folders for confidential business documents that only selected individuals can view or change. In a home environment, you might want to set up separate folders for different types of files, like photos, videos, or music.

For more information about this step, see “Creating Shared Folders” on page 33.

5. Access the shared folders.

For information about this step, see “Accessing Shared Folders” on page 37.

6. Protect your computer hard disks.

This process involves installing DiskSafe Express on each computer that you want to protect and specifying which hard disks or partitions to back up and how often backups should occur.

For more information about this step, see "Protecting Local Disks," beginning on page 77.

considerations, see “Step One: Determine Your Configuration” on page 12.

2. Set up your storage system.

This involves installing the hard disks, attaching any optional USB devices, attaching the storage system to your network, and powering up the system.

For information about this step, see “Step Two: Set up Your storage system” on page 13.

3. Install the Storage System Console.

You will need the Storage System Console to initialize your hard disks in step 4.

For information about this step, see “Step Three: Install the Storage System Console” on page 16

4. Initialize the Hard Disks.

This step loads firmware from the storage unit’s memory to each disk. “Step Four: Initialize the Hard

Disks” on page 17.

5. Configure your storage system.

Before you can use your storage system, you must perform some initial configuration tasks, like setting the date and time, and specifying how much space to use for file sharing and how much to use for backups. The System Setup wizard guides you through this process.

For information about this step, see “Step Five: Configure your Storage System” on page 20.

If you bought your Serial ATA 4-Drive NAS with the disks already installed and configured, and you do not want to change your disk configuration, skip step one and proceed with “Attaching USB Devices” in step two on page 15.

Step One: Determine Your Configuration

Before you start the physical installation of your storage system, decide which configuration is best suited to your needs. The configuration that you choose may affect the order in which you load the disks into your storage system, and you will need to specify your configuration choice when you reach “Step Five:

Configure your Storage System”.

Each supported configuration has a different balance of desirable characteristics, as shown in the table below. The configurations available to you depend on the number of disks installed in your storage system. Use this table to select your configuration based on the number of disks you intend to use and the characteristics that are of the highest priority to you.

Step Two: Set up Your storage system

Setting up your storage system consists of the following steps:

Installing the Hard Disks

Attaching USB Devices

Connecting the Storage System to the Network

Powering Up the Storage System

Installing the Hard Disks

If you have fewer than four hard disks in your storage system, you might want to add more at this time. You can add disks later, but changing your disk configuration once the disks contain data might cause data loss.

Note: The storage system must have at least one SATA hard disk with a capacity of at least 80

GB.

USRobotics strongly recommends that you install all the hard disks that you want to use in the storage system at this time in order to avoid data loss.

USRobotics also recommends that you use 4 disks of the same size for optimum performance.

Getting Started - 13

Serial ATA 4-Drive NAS

User Guide

To install the hard disks, you need a Phillips head screwdriver.

1. Remove the top hard disk tray from the storage system:

2. Near the front of the tray is a spacer containing four screws. Squeeze the tabs together to remove the spacer from the tray.

3. With the flat edge of the spacer up and the screws facing a flat surface (such as a table or desk top), flex the sides of the spacer apart from each other to release the screws.

4. Make sure that the hard disk is a SATA disk. It should have a SATA connector similar to the following:

5. Slide the new hard disk into the tray (connector end down and toward the back of the tray), and fasten

Getting Started - 14

Serial ATA 4-Drive NAS

the screws on the sides of the tray:

6. Slide the hard disk and tray back into the storage system until it snaps into place.

If you have fewer than four disks, load the bottom trays first and leave the top tray or trays empty.

User Guide

If you have four disks that are not the same size and you intend to use RAID 10, USRobotics recommends that you load the disks in ascending order of disk capacity, starting with the smallest disk in the bottom slot (slot 1),

Notes:

• If you install a hard disk that was previously part of a RAID, it will rebuild automatically.

• If you later replace all of the disks with higher-capacity disks, you will have to format those disks.

For more information about disk configurations, see the “Disk Configurations” on page 107.

7. Repeat steps 1 through 6 for each disk that you will use in your storage system.

Attaching USB Devices

If you have USB storage devices or printers, you can attach them to the USB ports on the back of the storage system.

Note: USB hubs are not supported. In addition, any USB disk must be formatted before you use

it with the storage system, and only the first partition of a FAT or FAT32 file system will be recognized. Do not attach the storage system directly to a USB port on a computer.

Connecting the Storage System to the Network

To connect your storage system to your network, insert one end of the supplied RJ-45 Ethernet cable into the Ethernet port on the back of the storage system. Then insert the other end into a network port.

Getting Started - 15

Serial ATA 4-Drive NAS

User Guide

Powering Up the Storage System

To power up the storage system, insert the power cable into the power connector on the back of the storage system and plug the other end into a power outlet.

Note: USRobotics recommends that you plug the storage system into a surge protector or

uninterruptible power supply to prevent damage to the system from power surges.

Once you have connected the power cable, make sure that the power switch on the back of the storage system is set to the on position. Then press and release the power button on the front of the storage system.

The power and Disk LEDs flash while the storage system is booting. Once the system has finished booting, the Disk LEDs stop flashing.

If the hard disk installation was successful, the Disk LED is blue. If there is a problem, the Disk LED is off. If this occurs, shut down the system, remove and inspect the hard disk for any installation problem, and reinstall it. To shut down the system, press and hold the power button for approximately five seconds until the Disk LEDs start flashing. Then release the power button; the storage system will shut down after a short period.

Step Three: Install the Storage System Console

Install the Storage System Console on a computer on the same network as the Serial ATA 4-Drive NAS:

1. Insert the USRobotics Installation CD-ROM into your CD-ROM drive.

2. If prompted, select your preferred language, then review the License Agreement and click Yes.

The installation CD prompts you to make a choice:

To change these proportions, enter a new percentage in either text box. (When you click anywhere on the page, the other text box updates automatically so that both percentages add up to 100%.) Then click Finish.

Caution: If you reduce the recommended amount of space to use for backups, you might

not be able to back up as many disks or use the maximum allowed number of backup versions. The recommended amount of space is greater than the total size of all your disks to accommodate multiple backup versions.

If you change these proportions after you finish the wizard, you will lose all data in your shared folders and all existing backups.

Backup of computer disks is provided through a separate backup and recovery utility. You can install DiskSafe Express from the USRobotics Installation CD-ROM for this purpose. For more information about DiskSafe Express, see the “Protecting Local Disks” on page 77.

9. in the confirmation window, click OK.

Accessing the Web User Interface

Once you have completed the initial configuration of your storage system, you can access the Web User Interface to add users, create shared folders, and perform other tasks related to managing your storage system.

There are two ways to access the Web User Interface:

• Using a Web browser (Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer)

• Using the Storage System Console (a Windows application that must be installed on each computer where you want to use it)

Using a Web browser, you can access the Web User Interface from any computer in your network, but you must know the name or IP address of the storage system. In addition, if you configured the storage system

Getting Started - 24

Serial ATA 4-Drive NAS

User Guide

to use a specific IP address, you might need to specify the IP address of the gateway in your network before you can successfully access the Web User Interface using a Web browser. First access the Web User Interface using the Storage System Console and then specify the gateway address (as described in

“Changing the Network Settings” on page 64.) and try to access it using a Web browser.

Using the Storage System Console, you can access the Web User Interface only from a computer in the same subnet as the storage system, but you do not have to know the name or IP address of the storage system or otherwise modify the network settings.

Note: The Storage System Console launches a Web browser, so the computer where you install the

Storage System Console must have Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer installed as well.

Accessing the Web User Interface Using a Web browser

To access the Web User Interface using a Web browser:

1. From any computer in your network, run Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer, enter the following in the address bar, and then press Enter:

http://storage_system

where storage_system is the name or IP address of the storage system.

Note: You can use the storage system name only if that name is registered with a DNS server on

your network.

When the login page appears, you can bookmark it so that you can quickly and easily access it the next time.

2. Log in to the Web User Interface (as described in “Logging In to the Web User Interface” on page 26).

Accessing the Web User Interface Using the Storage System Console

If you want to access the Web User Interface using the Storage System Console, you must install the Storage System Console on each computer from which you plan to manage the storage system. You can install the Storage System Console on any computer that runs one of the following operating systems:

• Microsoft Windows Server 2003

• Microsoft Windows XP

• Microsoft Windows 2000 Professional, Server, or Advanced Server with Service Pack 2 or newer

age system.

Note: The total storage capacity will be less than the total size of all your hard disks because some

of the disk space is needed for the operating system and management software.

In addition, the amount of used backup capacity will be greater than the total size of all the disks listed on the Backups page because additional storage space is needed for the data that has changed between backups.

On the Home page, you can also click Current Connections:

This displays information about Windows and Mac OS X users who are currently connected to shared folders, including which shared folder they are accessing and when they logged on.

Notes:

• If anyone accessed a shared folder using the guest user name (which is described in more detail in “Adding Users” on page 30), guest appears in the Users column, followed in parenthe- ses by the computer name.

• Due to the nature of the NFS protocol, Linux and other Mac connections are not listed on this page. Likewise, ongoing backup or recovery activities do not appear on this page.

• This page indicates only that a connection with a shared folder has been established; this does not necessarily mean that the user has opened any files in the shared folder.

Adding Users

By default, the storage system includes a user named guest that has a password of guest. However, you might want to add other users as well. For example, if you want to restrict access to a shared folder that contains confidential information, you would add at least one user and authorize that user to access that shared folder (and not authorize the guest user to access it). Adding a user for each individual or computer in your network provides maximum flexibility and security, enabling you to control exactly who can access what information.

In addition, only Windows and Mac OS X users can use the guest user name. If there are Linux users or Mac users who aren’t using OS X in your network, you must add users to allow those individuals to access any shared folders.

When you add a Windows or Mac OS X user, a folder with the same name as that person’s user name is automatically created on the storage system. Only that person can access that folder, and that person has full read/write access to it. (In the Storage System Console, this folder is identified as the home folder.)

You can add up to 64 Windows or Mac OS X users, and up to 64 Linux or other Mac users (for a total of up to 128 users).

Note: Since each Linux/other Mac user can represent multiple users, the number of actual users can

be higher.

To add a user:

2. Click Add.

3. Select the type of user that you want to add, and then click Next.

The operating system used by the user determines which option you should choose—Windows/Mac

OS X user (CIFS) or Linux/Other Mac user (NFS).

Note: Linux users and Mac users who are not using OS X access shared folders using the Network

File System (NFS). In this environment, access to shared folders is given to entire computers, not to individual users of those computers. However, in Windows and Mac OS X environments, each computer user can have individual access to a shared folder.

The user name can be up to 20 characters long and can include letters and numbers.

Note: If the user name and password that you specify here are the same as the person’s Windows user name and password, the person will not be prompted to provide a user name and password when accessing the shared folder.

Enter a computer description and the IP address or computer name of the person’s computer.

The Computer description can be the name of the person who typically uses the computer, or any other description that you want to provide to identify the computer in the Users list. This description can be up to 15 characters long.

The IP address or computer name is the IP address or the actual computer name in the computer's system configuration.

Note: Note: You can create a single user that actually represents multiple computers. In the IP address or computer name text box, you can use the wildcard characters * and ? to indicate a range of names. For example, include all computers in the subnet whose name begins with

*.company.com would include all computers in the domain company.com.

To put Windows or Mac OS X users into groups, see “Working with Groups” on page 46.

Creating Shared Folders

By default, the storage system includes a shared folder named public, and all Windows and Mac OS X users can access it and create, modify, or delete files there (unless you change the list of authorized users or their access rights as described in “Changing User Access to Shared Folders” on page 51).

However, you might want to create other shared folders as well. For example, in an office environment, you might want to create a shared folder for company policies that everyone can only view, and separate shared folders for confidential business files that only selected individuals or departments can view or change. In a home environment, you might want to create separate folders for different types of files, like photos, videos, or music. In addition, since only Windows and Mac OS X users can access the public folder, you would have to create shared folders if your network includes Linux or other Mac users.

You can create up to 64 shared folders. Users who can access and write to these shared folders can create additional sub-folders for organizing the files they store there.

To create a shared folder:

This name can be up to 256 characters long and can contain letters, numbers, hyphens, underlines, and spaces.

Note: Each shared folder name must be unique. For example, if you create a shared folder named

Photos for Windows/Mac OS X users, you cannot subsequently create a shared folder named Photos for Linux/other Mac users.\

In addition, the shared folder name cannot be the same as any Windows Mac OS X user name.

For Linux/other Mac users, the Mount path indicates that path that those users will specify when accessing the shared folder (as described in “Accessing Shared Folders” on page 37). As you enter a shared folder name in the text box, the same name is appended to the mount path. (You cannot change the first part of the mount path—/nas/NASDisk-00002/.)

If you accidentally add a user that you didn’t mean to add, select the user in the Authorized users list and click Remove. The user returns to the Unauthorized users list.

Note: If you created groups (as described in “Adding a Group” on page 47), you can perform this

step with the Unauthorized groups list.

This page shows all groups and all users. For example, if you created a group named Group1, and added User2 and User3 to that group, the Unauthorized groups list includes Group1, and the Unauthorized users list includes User2 and User3. If you select Group1 and click Add (Read-Only), Group1 moves to the Authorized groups list, but User2 and User3 do not move to the Authorized users list. This allows you to specify unique access rights for those users. For example, you could select User3 and click Add (Read/Write). This would mean that everyone in Group1 would have read-only access to the shared folder except User3, who would have read/write access to it.

On the Shared Folders page, the group name in the Users with access column is preceded by an @ symbol.

6. Repeat step 5 until you have defined all the desired access rights for all the desired users and groups, and then click Done.

7. Repeat steps 2 through 6 until you have created all the shared folders that you want to create at this time. (You can always create more shared folders later.)

When you have finished, you can log out (as described in “Logging Out of the Web User Interface” on page 72), or you can explore more of the features that the storage system has to offer. (For more information, see Chapter , "Managing Your Storage System," beginning on page 43.)

Accessing Shared Folders

Once you have added users and created shared folders, the users need to perform some simple steps to be able to access those folders. The procedure for doing this varies, depending on the user’s operating system. Each user can access only those shared folders that the user is authorized to access.

Note: If you change the IP address of the storage system, users who accessed the shared folders

using the previous IP address will be disconnected and must repeat the procedures described below using the new IP address.

If you’re using Windows, you have two options for accessing shared folders: you can use My Computer or Windows Explorer to map a drive letter to the shared folder, or you can install the Storage System Console and use that utility to map a drive letter to the shared folder. With the Storage System Console, you don’t have to worry about remembering the name of the storage server or the shared folders; it displays them automatically. However, the computer where you install the Storage System Console must be on the same network as the storage system.

Using My Computer or Windows Explorer

To access a shared folder using My Computer or Windows Explorer:

1. Open My Computer or Windows Explorer.

2. From the Tools menu, click Map Network Drive.

The Map Network Drive dialog box appears:

The exact appearance of this dialog box varies, depending on your operating system.

3. In the Drive list, select the drive letter that you want to assign to the shared folder.

4. In the Folder text box, enter the following:

\\storage_system\shared_folder

where storage_system is the name or IP address of the storage system, and shared_folder is the name of the shared folder. For example, if the storage system name is Storage and the shared folder name is Photos, you would enter the following:

\\Storage\Photos

Note: You can use the storage system name only if that name is registered with a DNS server on

your network.

Alternatively, you can click Browse and select the shared folder from the Microsoft Windows Net-

5. To automatically connect to this shared folder each time you log on to Windows, select Reconnect at logon.

If you clear this option, you must repeat this procedure each time you want to access the shared folder.

6. Click Finish.

7. If prompted, enter your user name and password for accessing this shared folder, and then click OK.

Note: If the user name and password for accessing the shared folder are the same as your

Windows user name and password, you are not prompted to provide a user name and password to access the shared folder.

In addition, once you provide your user name and password for accessing one shared folder, you are not prompted to provide it again when you access other shared folders to which you have access rights.

If the guest user has access to this shared folder, you can use guest as both the user name and password.

You can now access the shared folder from My Computer or Windows Explorer.

Using the Storage System Console

To access a shared folder using the Storage System Console:

1. Install the Storage System Console (as described in “Step Three: Install the Storage System Console” on page 16).

Managing Your Storage System

The Web User Interface lets you perform a number of tasks to help you get the most from your storage system:

• Managing Users—Add, modify, or remove users, or put users into groups.

• Managing Shared Folders—Create shared folders, rename existing shared folders, change which users can access existing shared folders or their access rights, and delete shared folders that you no longer want to keep.

• Managing Backups—View which computer disks are backed up, change the password for recovering a backup, or delete a backup.

• Setting Up E-mail Alerts—Specify whether or not e-mail notifications should be sent when a problem occurs, and who should receive the notifications.

• Upgrading the Firmware—Upgrade your storage system firmware to the latest version.

• Disconnecting USB Devices—If you’re using optional USB devices, you must disconnect them using the Web User Interface before you physically unplug them.

• Changing the System Settings—Change the storage system name or time and date settings, as well as the user name or password for logging in to the Web User Interface.

• Changing the Network Settings—Change the workgroup name, the storage system’s IP address(es), the gateway or DNS server settings, or the settings that allow the storage system to act as a DHCP server or FTP server.

• Reconfiguring Your Storage System Disks—Change the proportions of your storage system that are allocated to shared folders and backups, or change your disk configuration.

• Logging Out of the Web User Interface—Log out of the Web User Interface so that no one else can use your computer to make changes to the storage system.

• Shutting Down the Storage System—Shut down the storage system using the Web User Interface rather than pushing the power button on the storage system manually.

Managing Users

When you click Users in the navigation bar, the Users & Computers page appears. This page displays a

Managing Your Storage System - 43

Serial ATA 4-Drive NAS

User Guide

list of all currently configured Windows and Mac OS X users, as well as all Linux and other Mac computers.

Only the individuals or computers that appear on this page can access the shared folders or back up their local hard disks on the storage system. (In this guide, the term user refers to both individuals and computers.) You can add, modify, or remove users at any time.

Windows and Mac OS X users can also be put into groups. Putting users into groups makes it easier to give several users access to the same shared folder at once. For example, in an office environment, you might create one group for all users and give that group read-only access to a shared folder with corporate policies. You might then create separate groups for each department (such as Sales or HR) and give those groups read/write access to shared folders with information specifically for those groups (such as expense reports or company benefits). Each user can be a member of multiple groups.

Adding Users

To add a user, refer to “Adding Users” on page 30.

Modifying Users

For Windows and Mac OS X users, you can change the password used to access the shared folders, but not the user name. This change will not affect current connections, but will take effect the next time that a user tries to connect to a shared folder.

For Linux and other Mac users, you can change the IP address or computer name, but not the computer description. Changing this information immediately disconnects that computer from the shared folders.

Note: To change the user name or computer description, you must remove the existing user as

described in “Removing Users” on page 46, and then add a new user with the desired name or description as described in “Adding Users” on page 30.

To modify a user:

Managing Your Storage System - 44

1. In the navigation bar, click Users.

2. Select the radio button next to the user that you want to modify.

3. Click Edit.

The page that appears next varies, depending on the type of user you selected:

Removing Users

You can remove any user except the guest user.

If you remove a user who is currently connected to the storage system, that user remains connected until the user disconnects from the shared folder or shuts down the computer.

Caution: When you remove a Windows/Mac OS X user, the folder whose name matches that user

name is automatically deleted. If you’re removing the user simply to change the person’s user name, you might want to have the user copy any data from this folder to another location to ensure that it is not lost.

To remove a user:

1. In the navigation bar, click Users.

2. Select the radio button next to the user that you want to remove.

3. Click Remove.

4. When prompted to confirm the removal, click Yes.

The user no longer appears in the list on the Users page.

Working with Groups

Windows and Mac OS X users can be put into groups, which makes it easier to give several users access to the same shared folder at once.

When you click Users in the navigation bar and click Groups in the left pane, the page displays a list of all currently configured groups. When you select a group in the Groups list, the members of that group

appear in the adjacent Members list.

You can add a group, modify the group membership, or remove groups at any time.

User Guide

Adding a Group

When you create a group, you typically specify which users should be members of that group, although you can create an empty group and add users later. (You must add users as described in “Adding Users” on page 30 before you can add those users to a group.)

Each user can be a member of multiple groups. For example, the user Alice might be a member of both the Marketing and Executives groups.

You can create up to 16 groups.

To add a group:

1. In the navigation bar, click Users.

2. In the left pane, click Groups.

the last user. All users between the first and last selected user are selected.

To select multiple, non-contiguous users, hold down the Ctrl key as you select each user.

Changing the Group Membership

You can change which users are members of each group at any time. When you add a user to a group, that user immediately has access to all the shared folders that the group is authorized to access. However, if you remove a user from a group, the change does not take effect until that user disconnects from the shared folder or shuts down the computer.

For example, the user Alice might be a member of both the Marketing and Executives groups. The

Managing Your Storage System - 48

Serial ATA 4-Drive NAS

User Guide

Marketing group might have read-only access to the Budget shared folder, while the Executives group might have read/write access. As a member of the Executives group, Alice would have read/write access to that shared folder. If Alice is currently connected to that shared folder and you subsequently remove her from the Executives group, she will continue to have read/write access to that folder until she disconnects or shuts down her computer. The next time she connects, she will continue to have access to the shared folder (since she is still a member of the Marketing group), but she will be able to only view the files there; she will not be able to add, modify, or delete any files.

To change the group membership:

1. In the navigation bar, click Users.

2. In the left pane, click Groups.

3. In the Groups list, select the group whose membership you want to change.

User Guide

The selected users move from one list to the other.

On the Groups page, when you select this group in the Groups list, the adjacent Members list imme- diately reflects the changes you just made.

Removing a Group

Removing a group does not remove the users that are members of that group; it simply means that the group will no longer appear in the Groups list on the Groups page. The users remain listed on the Users & Computers page.

However, removing a group can affect access to shared folders. When you remove a group, the members of that group will no longer have access to any shared folders that the group was authorized to access unless they were granted individual access as well.

For example, the Executives group might include Alice, Bob, and Carlos, and that group might have read/ write access to the Budget shared folder. If you remove the Executives group, Alice, Bob, and Carlos remain users, but they will no longer have any access to that shared folder.

On the other hand, if the Executives group had read/write access to the Budget shared folder, but Alice had read-only access, when you remove the group, Bob and Carlos will no longer have access to the Budget shared folder (since their access rights were determined by their group membership), but Alice will continue to have read-only access, since that access right was granted to her on a user level.

To remove a group:

1. In the navigation bar, click Users.

2. In the left pane, click Groups.

3. In the Groups list, select the group that you want to remove.

4. Click Remove.

5. When prompted to confirm the removal, click Yes.

The group no longer appears in the Groups list.

Managing Shared Folders

When you click Shared Folders in the navigation bar, the page displays a list of shared resources, including both shared folders and USB devices. When you select an item in the Shared folders list, the users and groups that can access that item appear in the Users with access list. (For groups, the group

name is preceded by an @ symbol.)

The Shared folders list also includes usbdisk1 and usbdisk2, whether or not any USB disks have been connected to the storage system.

You can create additional shared folders and delete them at any time. For both shared folders and USB disks, you can change which users can access them and what they can do with the subfolders and files there.

Adding Shared Resources

To create a shared folder, refer to “Creating Shared Folders” on page 33.

Changing User Access to Shared Folders

For any shared folder that appears in the Shared folders list or any USB disk, you can change which users can access it and what level of access they have.

Note: By default, all users have read/write access to the public folder. You can change the user

assignments or access rights for the public folder.

When you add a user to the list of authorized users for a shared folder or USB disk, that change takes effect immediately. However, if you remove a user from the list of authorized users, or if you change the user’s access rights, the change does not take effect until that user disconnects from the shared folder or USB disk, or shuts down the computer.

For example, the user Alice might have read/write access to the Budget shared folder. If Alice is currently connected to that shared folder and you subsequently remove her from the list of authorized users or change her access level to read-only, she will continue to have read/write access to that folder until she disconnects or shuts down her computer. The next time she connects, she will either not have access (if

she was removed from the list of authorized users), or she will be able to only view the files there (if her access level was changed).

To change user access to shared folders and USB disks:

1. In the navigation bar, click Shared Folders.

2. In the Shared folders list, select the shared folder or USB disk whose user access you want to change.

3. Click Assign Access.

4. If you selected a shared folder or a USB disk to which you previously assigned users, go to step 5.

If you selected a USB disk to which you did not previously assign users, select the type of user that you want to assign to this USB disk, and then click Next.

The operating system used by the user determines which option you should choose—Windows/Mac

OS X user (CIFS) or Linux/Other Mac user (NFS).

Note: Linux users and Mac users who are not using OS X access shared folders using NFS. In this

environment, access to shared folders is given to entire computers, not to individual users of those computers. However, in Windows and Mac OS X environments, each computer user can have individual access to a shared folder.

The page that appears next varies, depending on what type of users can access the shared folder you selected:

• Windows/Mac OS X user (CIFS)

Notes:

• To change the access level for a user, select the user in the Authorized users list and click Remove. Then select that user in the Unauthorized users list and click either Add (ReadOnly) or Add (Read/Write), depending on the access level you now want the user to have.

• If you created groups (as described in “Adding a Group” on page 47), you can perform this step with groups as well.

Deleting a Shared Folder

Once you have created a shared folder, you can delete it at any time. When you delete a shared folder, any users who are currently accessing it are immediately disconnected from it.

Caution: Deleting a shared folder deletes all the subfolders and files in that shared folder. If you want to

delete only selected subfolders or files, access the shared folder (as described in “Accessing

Shared Folders” on page 37) and delete the desired items.

Notes:

• You cannot delete the public folder.

• You cannot delete the contents of a USB disk using the Shared Folders page. To delete its contents, you must give yourself read/write access to that disk (as described in “Changing User Access

to Shared Folders” on page 51), access the disk (as described in “Accessing Shared Folders” on

page 37), and then delete the desired folders and files.

To remove the USB disk from the storage system, use the Web User Interface to disconnect it (as described in “Disconnecting USB Devices” on page 60). Then physically unplug the USB disk from the storage system.

Even after you physically unplug the USB disk, it remains in the Shared folders list. This ensures that you don’t have to re-assign users if you later reconnect the USB disk.

To delete a shared folder:

1. In the navigation bar, click Shared Folders.

2. In the Shared folders list, select the shared folder that you want to delete.

Managing Your Storage System - 54

User Guide

3. Click Delete.

4. When prompted to confirm the deletion, click Yes.

The shared folder no longer appears in the Shared folders list, and all associated subfolders and files are deleted.

Managing Backups

Once the users have used DiskSafe Express to back up their computer hard disks to the storage system (as described in "Protecting Local Disks," beginning on page 77), the Backups page displays a list of those users’ computers, the size of each protected disk, the date and time of the last four backups, and the backup disk ID (the number used to identify the backup on both the storage system and on the Status page in DiskSafe Express).

If a user ever has to recover a disk using the recovery CD, the user will be prompted for a password to do so. The user had to provide this password when protecting the disk. However, if the user forgets it, you can reset the password using the Web User Interface.

In addition, when a user removes protection for a disk, the existing backups are not deleted. The user can re-use the allocated space for new backups, or you can delete those backups manually using the Web User Interface.

Changing the Recovery CD Password

To change the recovery CD password:

1. In the navigation bar, click Backups.

2. In the Computer name list, select the name of the computer whose recovery CD password you want to change.

3. In the Recovery CD password text box, type the password to use.

This password must be 12–16 characters long.

4. Click Change Password.

The user must provide this password when recovering a disk from this storage system using the recovery CD.

Deleting a Backup

You can delete all backups of a given disk, but you cannot delete just an individual backup from a specific date and time.

Note: If you delete all backups of all disks for a particular computer, that computer no longer appears

on the Backups page. However, that computer name remains in the storage system and counts toward the total number of computers that are allowed to back up to the storage system. If you want to delete all backups of all disks and the computer name, refer to the next section, “Deleting

a Client.”

To delete all backups of a disk:

1. In the navigation bar, click Backups.

2. Select the radio button adjacent to the disk whose backups you want to delete (in the second Select column).

3. Click Delete Backup.

4. When prompted to confirm the deletion, click Yes.

The disk no longer appears on the Backups page, and all backup versions are deleted. If only one disk was protected, the computer name disappears from the page as well.

Note: If you delete a backup and the user did not previously remove protection for that disk, when

the user subsequently accesses DiskSafe Express, the Status page will indicate that the backup of the protected disk is offline. To back up the disk once again, the user must remove protection and then protect the disk again. For more information, refer to “Removing

Protection” on page 104 and “Protecting Your Disks” on page 86.

Deleting a Client

If you remove DiskSafe Express from a particular computer, or if you change the computer name, the original computer name remains on the storage system and counts toward the total number of computers that are allowed to back up to the storage system. To both delete all backups of all disks for a particular computer and the computer name, you must delete the client.

To delete a client:

1. In the navigation bar, click Backups.

2. Select the radio button to the left of the computer whose backups and computer name you want to delete from the storage system (in the first Select column).

3. Click Delete Client.

4. When prompted to confirm the deletion, click Yes.

All backups of all disks associated with this computer are deleted, and the computer name is also deleted from the storage system.

Note: If you delete a client and the user did not previously remove protection for that disk, when the

user subsequently accesses DiskSafe Express, the Status page will indicate that the backup of the protected disk is offline. To back up the disk once again, the user must remove protection and then protect the disk again. For more information, refer to “Removing

Protection” on page 104 and “Protecting Your Disks” on page 86.

Setting Up E-mail Alerts

The Alerts page allows you to set up the storage system to notify up to three people via e-mail if a problem occurs—for example, if one of the disks fails, or if insufficient space is available for creating new files or

To take advantage of this feature, you must have access to an SMTP e-mail server, either within your own network or through an Internet service provider.

Note: The e-mail might not be sent immediately when the problem occurs, but will be sent within an

hour of the event. In addition, if the problem is fixed within an hour of its occurrence—for example, if you replace the disk that failed—the alert will not be sent.

To set up e-mail alerts:

1. In the navigation bar, click Advanced.

2. Specify whether or not the storage system should send e-mail notifications when a problem occurs by selecting or clearing the Send e-mail notifications check box.

If you select this option, you must provide the fully qualified domain name or IP address of your e-mail server and at least one e-mail address.

If you clear this option, e-mail notifications will not be sent, and all the related fields on this page appear dimmed. However, if you previously entered information on this page, that information is retained so that you can easily re-enable e-mail notifications later.

also allows you to upgrade it if newer firmware becomes available.

For additional security, you must enter your administrator password in order to upgrade the firmware.

Caution: When you upgrade the firmware, the storage system restarts, and access to the Web User

Interface is temporarily interrupted. In addition, users will not be able to access the shared folders while the system restarts. If users have shared files open, data might be lost. Be sure to have all users save their changes and close any open files before you upgrade the firmware.

Restarting the storage system when a backup is occurring will not have any adverse effect; the backup will resume automatically when the storage server resumes operation. However, restarting the storage system when a disk is being recovered can potentially corrupt the user’s operating system, and the user will have to recover the system disk using the recovery CD (or, if the system disk was not protected, re-install the operating system). Be sure to upgrade the firmware only when recovery is not occurring.

To upgrade the firmware:

1. In the navigation bar, click Advanced.

2. In the left pane, click Firmware.

3. In the Firmware file text box, enter the path and file name for the firmware package (such as D:\fs20060921.pkg), or click Browse and select the file from the displayed list.

4. In the Administrator password text box, enter the password that you use for logging in to the Web User Interface.

5. Click Upgrade.

6. When the confirmation message appears, click OK.

Disconnecting USB Devices

The USB page displays a list of all USB devices that are currently attached to the storage system, including the type of device it is, the manufacturer, and the name. USB disks are identified by the names usbdisk1 and usbdisk2. USB printers are identified by the names usbprinter1 and usbprinter2. (These

names cannot be changed.)

When you plug a USB device into the storage system, the storage system automatically detects it and adds that device to the USB page. (You might need to click Scan to update the display.)

However, when you want to unplug a USB device from the storage system, you must first use the Web User Interface to disconnect it. This prevents data corruption and other potential problems with the device. Once the USB device has been disconnected via the Web User Interface, you can unplug it.

To disconnect a USB device:

1. In the navigation bar, click Advanced.

2. In the left pane, click USB.

3. In the list of USB devices, select the device(s) that you want to disconnect.

4. Click Disconnect.

5. When the confirmation message appears, click OK.

You can now unplug the USB device.

Note: If you inadvertently disconnect a USB device that you want to retain, unplug it from the

storage system, plug it back in, and then click Scan. This reactivates the USB device.

Since the USB device always remains on the Shared Folders page, any user assignments are always retained.

Changing the System Settings

The System page displays the settings that you specified when you initially configured the storage system,

such as the storage system name, and the current date and time.

Serial ATA 4-Drive NAS

User Guide

You can change these settings at any time.

Note: If you change the name of the storage system, be sure to also change that name in any local

hosts files or on the DNS server in your network. The storage system does not register its name with your DNS server automatically.

For example, if users connected to the storage system using its IP address, changing the name has no effect. However, if they connected using the name, they must disconnect from their shared folders (as described in “Disconnecting from Shared Folders” on page 118) and then access the shared folders again using the new name (as described in “Accessing Shared Fold-

ers” on page 37).

If the DiskSafe Express users connected to the storage system using its name, they must remove protection from all disks that connected to this storage system (as described in “Remov-

ing Protection” on page 104) and protect their disks again (as described in “Protecting Your Disks” on page 86), using the new name.

Serial ATA 4-Drive NAS

User Guide

You can change these settings at any time.

Note: Changing the IP address or subnet mask can have several effects:

• If you access the Web User Interface using the Storage System Console or using the storage system’s IP address, access to the Web User Interface will be disrupted and you will have to access it again using the new IP address.

• Users who accessed the shared folders using the previous IP address will be disconnected and must access them again using the new IP address (as described in “Accessing Shared Folders” on page 37).

• Users who backed up their disks to the storage system using the previous IP address must remove protection for all affected disks (as described in “Removing Protection” on page 104) and protect their disks again (as described in “Protecting Your Disks” on page 86), removing the storage system from the list of backup locations and adding it again using the new IP address.

Users who backed up their disks to the storage system using the storage system name do not have to remove protection from their disks or remove the storage system from the list of backup locations. However, they must start DiskSafe Express so that it can retrieve the new IP address.

You can also configure the storage system to act as a DHCP server. In other words, the storage system can assign IP addresses to other computers in your network, simplifying the network configuration of each individual system.

In addition, your storage system can act as an FTP server. This allows all Windows or Mac OS X users to use a Web browser to access the public folder. They can also access their personal folder that was created automatically when their user name was added to the storage system (as described in “Adding

Users” on page 30). For more information, refer to “Accessing the Storage System through FTP and Te ln e t” on page 75.

The DHCP settings

If your network includes a DNS server, and the storage system uses a specified IP address rather than obtaining one from the DHCP server, enter the primary IP address in the Preferred DNS server text boxes and the secondary IP address in the Alternate DNS server text boxes.

If your network does not include a DNS server, or if the storage system obtains its IP address from the DHCP server, leave these text boxes blank. (If thestorage system obtains its IP address from a DHCP server, the DNS server IP address will be obtained from the DHCP server as well.)

If you want to use the storage system as a DHCP server, in the Port 1 group box, select Use this IP address and enter the IP address and subnet mask in the subsequent text boxes.

Then select the Enable DHCP server check box, enter the beginning IP address in the Starting IP address text boxes, and enter the last IP address in the Ending IP address text boxes.

For example, if the Starting IP address is 192.168.0.103 and the Ending IP address is 192.168.0.107, the storage system will allocate the IP addresses

192.168.0.103, 192.168.0.104, 192.168.0.105, 192.168.0.106, and

192.168.0.107 to the first five computers that try to obtain their IP addresses from the storage system. As soon as one of those computers shuts down or otherwise loses its network connection, that IP address will be assigned to the next computer that tries to obtain its IP address from the storage system.

Accessing the Storage System through FTP and Telnet

FTP

If you enabled the storage system to act as an FTP server, all Windows or Mac OS X users can use a Web browser to access the public folder and their personal folders. For information about enabling the storage system to act as an FTP server, see “Changing the Network Settings” on page 64

Note: Even if you changed the access rights to the public folder (for example, to prevent a particular

user from accessing it altogether or to limit a user to read-only access), all existing users have full read/write access to the public folder when accessing it via FTP.

To access the storage system using FTP:

1. At any Windows or Mac OS X computer, open a Web browser, enter the following in the address bar, and press Enter:

ftp://user_name@storage_system

where user_name is the user name as defined on the storage system and storage_system is the name or IP address of the storage system (for example, ftp://user1@storage or ftp://user1@192.168.0.101).

Note: You can use the storage system name only if that name is registered with a DNS server on

your network.

You can use guest as the user name, but you will be able to access only the public folder.

2. If prompted, enter your user name and password for accessing shared folders, and then click OK.

If you used the guest user name, the password is also guest.

3. Double-click any of the displayed folders or files to open them.

You have full read/write access to all the folders and files in both the public folder and your personal folder.

Even if you browse to other websites, you remain logged in until you close the browser window. (That is, you can return to the FTP site using the Back button in your browser window.

Protecting Local Disks

Even if most of your data is stored and protected on your storage system, your operating system files, applications, and many other files still reside on each individual computer in your network. If one of those local disks fails, it can take many hours to re-install and reconfigure the operating system and applications on a new or repaired hard disk, and some files might be completely lost.

DiskSafe Express is a software application designed to address this issue. On each computer where it is installed, DiskSafe Express provides reliable data protection and rapid data recovery in the event of a system crash or disk failure.

DiskSafe Express protects Windows desktops and laptops by backing up their local disks or partitions to the storage system. To make sure that you have recent copies of your local disk, DiskSafe Express can automatically perform a backup at regularly scheduled intervals—either once a day or once a week, whichever you prefer. (You can also disable automatic backups and just perform backups manually at a time of your choosing.) Up to four backups are saved on the storage system; each time a new backup is performed, the oldest backup is automatically deleted.

Local computer running

DiskSafe Express®

LAN

USR 8700 Attached Storage

copies of local disk

To ensure that valuable storage space isn’t used up by duplicate data, when DiskSafe Express performs each subsequent backup, it copies only the data that has changed since the last time a backup was performed. This also minimizes the impact on your network.Through unique technology on the storage system, each backup is a complete point-in-time image. You can view or recover the entire disk or partition exactly as it existed at a particular date and time.

Whenever you want to recover data from the storage system, you can do so quickly and easily. If you need to recover just a few folders or files, you can access the desired backup and copy what you need back to your local disk. If the protected disk isn’t your system disk (that is, the disk that contains the Windows operating system files that the computer uses when it runs), and you need to recover the whole disk, you can do so using DiskSafe Express. And if the protected disk is your system disk, and you need to recover the whole disk, you can do so using the recovery CD. Recovering the whole disk makes it contain exactly the same data that it contained at the time the backup was performed—you don’t have to reinstall or reconfigure the operating system or applications.

Getting Started

System Requirements

Each computer where DiskSafe Express is installed must have the following:

• One of the following operating systems:

• Microsoft Windows XP Home Edition or Professional with Service Pack 2 or newer

• Microsoft Windows Server 2003

• Microsoft Windows 2000 Professional, Server, or Advanced Server with Service Pack 4

• Microsoft iSCSI Initiator 2.0

Note: For information about downloading and installing this item, refer to the next section,

“Installing the Microsoft iSCSI Initiator.”

User Guide

• 20 MB free hard disk space

Note: DiskSafe Express requires the Intelligent Management Agent (IMA), which is installed

automatically if it is not already installed. IMA requires an additional 5 MB of free hard disk space (for both the application and associated log file data).

Microsoft .NET Framework 1.1 is also required and installed automatically if it is not already installed. The .NET Framework requires approximately 40 MB of additional free hard disk space.

In addition, if you’re using a firewall on the computer that you plant to protect, open TCP port 11762 on the firewall. This ensures that DiskSafe Express can communicate with the storage system.

User Guide

If your computer has an Internet connection, the license is activated automatically. If your Internet connection is temporarily down, your license will be activated automatically the next time you run DiskSafe Express with a restored Internet connection. If this computer does not have an Internet connection, you must perform offline activation (as described in the previous section.)

Protecting Your Disks

After you install DiskSafe Express and restart your computer, the Protect a Disk wizard runs automatically. Using this wizard, you can specify which disk or partition you want to back up, where the backups should be stored, when automatic backups (if any) should occur, and what password you want to use for the recovery CD. If you cancel this wizard, you can start it again at any time using the following procedure.

To protect a disk:

1. Click Protect a Disk.

The Protect a Disk wizard runs.

Protecting Local Disks - 86

Serial ATA 4-Drive NAS

2. In the Available disks list, select the disk or partition that you want to protect.

User Guide

Even if your computer has only one hard disk, two items appear in this list. The first item represents the entire hard disk, and the second item represents the partition on that disk. (If there’s only one partition on the disk, the partition is the same as the entire disk.)

If your hard disk is divided into multiple partitions, this list displays one item for the entire hard disk, and one item for each partition. If your computer has multiple hard disks, this list displays an item for each entire disk and an item for each partition on each disk. Each partition is identified by its drive letter.

Note: Dynamic disks are not supported.

If you select an entire disk, all the partitions on that disk are protected as a single entity. This means that you can’t later recover only one partition; you have to recover the entire disk. If you select just a partition, you can subsequently recover just that partition.

In addition, you can recover a data disk or partition using DiskSafe Express, but you can recover a system disk or partition only using the recovery CD, so if you have separate partitions for your system information and your data, you might want to protect each one separately.

Note:

• If your computer has only one disk with one partition, select the disk.

• If your disk has a system partition and a data partition, select one of the partitions and complete the wizard. Then run the wizard again and protect the other partition. This provides complete protection with maximum flexibility.

• If you have several disks and several partitions on each, select either one of the disks or one of the partitions and complete the wizard. Then run the wizard again and protect another disk or partition.

What to do next:

In this case Go to this step

You never previously completed the Protect a Disk wizard 3

You previously completed the Protect a Disk wizard and connected to a storage system

You previously protected this disk and removed protection (as described in “Removing

Protection” on page 104)

3. When the Add Storage System dialog box appears, DiskSafe Express automatically scans your subnet for storage systems. Any storage systems that are detected appear in the Discovered storage systems list. (It might take a few seconds to complete the scan. You can cancel it at any time by clicking Cancel on the scanning message box.)

From the Discovered storage systems list, select the storage system where you want to back up the selected disk. The name of the storage system automatically appears in the Storage system name or IP address text box.

If no storage systems are automatically discovered, or if you want to back up your disk to a different storage system, enter the name or IP address of the desired storage system in the Storage system

name or IP address text box.

Note: You can enter a storage system name only if that name is registered with a DNS server on

your network.

Then click OK.

Note: If an authentication error occurs, make sure the name or IP address of the storage system is

correct, and that your computer is connected to the network.

4. From the Backup locations list, select the storage system to use for backups of this disk or partition.

Protecting Local Disks - 88

(The first backup location in the list is selected by default.)

User Guide

If you want to scan the network for new storage systems, or add a new one manually, click Add and repeat step 3.

If you want to remove a storage system that’s not valid or that you no longer want to use, select the storage system from the Backup locations list, click Remove, and then click Yes to confirm the removal. (You can remove a storage system only if it is not currently being used to protect another disk.)

Once you have selected the desired backup location, click Next and go to step 6.

5. If you previously protected this disk and removed protection, specify whether or not you want to re-use the existing backup or create a new one:

If you select Re-use the existing backup, you must select which backup to re-use from the list. The disk ID and size also appear to help you identify exactly which backup to use. Then click Next and go

Protecting Local Disks - 89

Serial ATA 4-Drive NAS

to the next step.

If you select Create a new backup and click Next, you must select the desired backup location as described in step 4.

6. Specify when you want backups to occur.

User Guide

For example, if you want backups to occur every day, select Daily from the Recurrence list. If you want backups to occur once a week, select the day of the week from the Recurrence list. Then select the time.

If you don’t want backups to occur automatically, select Not Scheduled from the Recurrence list. (The Time list appears dimmed.) Backups will occur only when you start one manually (as described in

“Manually Backing Up Your Disk” on page 92).

Notes:

• Only four backups of each protected disk or partition are saved on the storage system, so if you back up your disk every day, you’ll be able to recover data from only the last four days. If you back up your disk once a week, you’ll be able to recover data from four weeks ago, but the most recent backup might be as many as six days old.

• Although DiskSafe Express is specifically designed to perform backups without affecting your other computer activities, you might want to schedule backups for a time when they’ll have the least impact on your system, like during lunch or after business hours (if you leave your computer running overnight). If you’re protecting multiple disks or partitions, it is recommended that you schedule each backup to occur at a different time.

• Once you complete this wizard, if a backup does not occur at its scheduled time for any reason, a message will appear, advising you of this and giving you the option to perform the backup immediately or wait until the next scheduled backup.

7. Specify whether or not to back up your disk as soon as you finish the wizard by selecting or clearing the Back up now check box, and then click Next.

If you clear this option, the disk will be backed up at the next scheduled time or the next time you perform a manual backup.

8. If you ever need to recover your disk using the recovery CD, you’ll be prompted for a password. In the

Recovery password text box, enter the password that you’d like to use, enter it again in the Retype your password text box, and then click Next.

Notes:

• The recovery password must be 12–16 characters long.

• The same password is used for all disks backed up to the same storage system. If you subsequently protect a second disk using the same storage system, you will not be prompted to provide this password again. However, if you protect a second disk using a different storage system, you will be prompted to provide a password for that storage system.

• You can change this password later using DiskSafe Express (as described in “Changing the

Recovery CD Password” on page 95).

User Guide

If you selected the Back up now check box, the backup process begins as soon as you click Finish, and you can review its progress on the Status page in DiskSafe Express.

10. If you want to protect additional disks or partitions, repeat this procedure for each one.

Note: If you subsequently change the drive letter of a protected disk or partition, you must restart

DiskSafe Express to update this application.

Manually Backing Up Your Disk

Once you protect a disk, it is automatically backed up at regular intervals (unless you chose Not Scheduled from the Recurrence list when you completed the schedule). However, you can also back up

a disk manually at almost any time. For example, if you’re about to install a new application, you might want to back up your disk right before you do that so that if any problems occur, you can recover your disk to the state it was in immediately before you installed the application.

Note: You can manually back up a disk only if a backup or recovery is not currently occurring.

To manually back up a disk:

Protecting Local Disks - 92

1. Click Status.

User Guide

2. In the Protected disk list, select the disk that you want to back up.

3. Click Back Up Now.

The Current activity area displays information about what’s happening, the percentage of the backup that has completed, and the speed at which the data is being sent over the network. The Progress bar graphically indicates how much of the backup is complete.

To stop a backup in progress, click Stop Current Activity.

Stopping a Backup or Recovery in Progress

Once a backup or recovery starts, you can stop it at any time—for example, if you notice that your system is not responding as quickly as you’d like, and you want to free up processing bandwidth for other tasks.

When you stop a backup in progress, that backup won’t appear in the list of backups on the Restore page, and any changed data that was not copied to the storage system will be copied during the next backup.

When you stop a recovery in progress, the local disk or partition is left in an incomplete state, and you must recover it again later before you can use it.

To stop a backup or recovery in progress:

4. Click Apply.

The schedule change takes effect immediately, and the date and time of the next scheduled backup appears in the Next backup area.

Changing the Recovery CD Password

When you protect a disk, you specify what password to use for recovering the disk using the recovery CD. However, you can change this password at any time.

Note: The same password is used for all disks backed up to the same storage system. If you backed up

multiple disks to the same location and change the password for one, the password is changed for all of them. However, if you backed up one disk to one storage system and a different disk to a different storage system, each disk can have a different recovery CD password.

To change the recovery CD password:

Recovering Data

With DiskSafe Express, there are several ways to recover data from your backups. The best method to use depends on what you want to do:

• Recover selected folders, files, or sections of files—If you accidentally permanently deleted a folder or file that you want to recover, or if you just want to retrieve some information from a file that you changed, you can access the backup that contains the desired data and copy it to your local disk.

You can also use this procedure to try out different “what if” scenarios—for example, changing the format of the data in a file—without adversely affecting the data on your local disk.

For more information, refer to “Recovering Files from a Backup” on page 97.

• Recover an entire non-system disk or partition—If you protected a disk or partition that isn’t being used to run the operating system, you can recover that disk or partition using DiskSafe Express. You might need to do this if the disk has become corrupted or the data has been extensively damaged. The entire disk or partition will be restored to its exact state at the time of the selected backup.

Caution: When you do this, you will lose any data that was written to the disk after the time of the

selected backup, as well as any backups that were performed after the backup you’re recovering. You might want to copy any newer files that you want to keep to another disk before you recover the disk. To copy files from a backup, refer to “Recovering Files from

a Backup” on page 97.

In addition, if network errors occur or the storage system shuts down during recovery, your operating system might become unstable, and you will have to recover it using the recovery CD (or re-install the operating system if you did not protect your system disk). Be sure to recover your disks or partitions only when your environment is stable.

You can continue to use your computer for other tasks while the data is being recovered, although not any applications or files located on the disk or partition that you’re recovering.

For more information, refer to “Recovering a Non-system Disk or Partition” on page 99.

• Recover an entire system disk or partition—If you need to recover your system disk or partition— that is, the disk or partition used to run the operating system—you can do so using the recovery CD. This is particularly useful if the hard disk has failed and has been repaired or replaced, or if you want to duplicate an existing disk configuration for another computer. The entire disk or partition will be recovered to its exact state at the time of the selected backup. However, you won’t be able to use your computer until all this process is complete.

For more information, refer to “Recovering a System Disk or Partition” on page 101.

Recovering Files from a Backup

To recover selected folders, files, or sections of files from a backup:

Protecting Local Disks - 97

1. Click Restore.

Serial ATA 4-Drive NAS

User Guide

2. In the Protected disk list, select the disk that contains the folders or files that you want to recover.

3. In the Backups list, select the backup from the desired date and time.

You can select only a backup for which No appears in the Backup View Open column.

4. Click View Backup.

5. When the confirmation message appears, click OK.

After a few moments, a window opens automatically, displaying all the data associated with the selected backup. You can now open the folders and files in the backup view to make sure they contain the information you want, and copy any of the data to your local disk.

Caution: You can open and change the files in the backup view, and even create new folders or

files there. However, as soon as you close the view (as described in the next step), all the changes will be lost. The next time you view the backup, it will appear the way it existed at the time the backup was created.

Protecting Local Disks - 98

Serial ATA 4-Drive NAS

User Guide

Notes:

• If the first drive letter after your local disks is mapped to a shared network folder, you must use Disk Management to change the drive letter assigned to the backup view so that you can access it.

For example, if your system disk is mapped to C:, your CD-ROM drive is mapped to D:, and a shared network folder is mapped to E:, and you view a backup, you will continue to see the shared network folder when you explore E:, and you will not see a new drive letter for the backup view. (Internally, the backup view is also mapped to E:, since that was the first drive letter after the local disks.) However, when you use Disk Management to change the drive letter for the backup view from E: to F:, you will be able to see both the shared network folder (E:) and the backup view (F:).

To change the drive letter, right-click My Computer and click Manage. In the left pane, click Disk Management. In the right pane, right-click the volume, click Change Drive Letter and Paths, click Change, select the desired drive letter from the list box, and then click OK on each dialog box. You can now access the backup view using the specified drive letter.

• Windows caching can affect the content of the backup view. If the content does not appear to be correct, restart your computer and check again.

• You can view more than one backup simultaneously. Simply repeat steps 3 and 4 for each backup that you want to view.

• If you open a backup view for a partition that cannot be explored (such as an EISA partition), the backup view is closed automatically.

• When a backup view is open, that backup will not be deleted to make room for new backups until it is closed or unless the storage system runs critically low on resources. If you view the oldest backup, and the maximum number of backups is reached, new backups cannot occur until the view of the oldest backup is closed (as described in the next step).

• When you close the DiskSafe Express application window, you are prompted to close all open backup views. If you click Yes, both the application window and all open views are closed. If you click No, both the application window and all open views remain open.

6. When you have finished viewing or copying all the desired data, select the backup in the Backups list and click Close View.

The Windows Explorer window closes automatically, and the Backup View Open column for the selected backup now displays No.

Recovering a Non-system Disk or Partition

You can recover a non-system disk or partition only as long as that disk or partition is not currently being backed up, and only as long as a more recent backup view is not open. For example, if you created

backups on Monday and Tuesday, and Tuesday’s backup view is open, you cannot recover Monday’s backup until you close Tuesday’s view.

In addition, if you recover a partition and other partitions of that same disk are also protected, protection for

those other partitions temporarily stops until the selected partition is recovered.

Caution: When you recover a disk or partition, you will lose any data that was written to the disk

after the time of the selected backup, as well as any backups that were performed after the backup you’re recovering. You might want to copy any newer files that you want to keep to another disk before you recover the disk. To copy files from a backup, refer to

“Recovering Files from a Backup” on page 97.
