An autoloader is a backup device that has multiple storage slots. Each storage slot contains a cartridge. This has tw

• The overall storage capacity is much greater.

• More impor tantly, each cartridge can be allocated to a speciﬁc backup task; for example,

one cartr way, backup applications are able to implement tape rotation strategies that accommodate differing backup requirements for daily, weekly, monthly, yearly backups. Please see “Backup scenarios using the HP D2D Backup System” on page 55 for worked examples.

o a dvantages over standalone tape drives:

idge can hold Monday’s data, another can hold Tuesday’s data, and so on. In this

Backup devices and slots

Backup devices appear to the host as locally-attached tape devices, but physically, they use disk space on the HP D2D Backup System which, as in tape terminology, is referred to as slots or cartridges.

Depending on your data protection strategy, you may conﬁgure each backup device as a standalone HP StorageWorks Ultrium Tape Drive or, more typically, as an HP StorageWorks 1x8 G2 Tape Autoloader with attached Ultrium Tape Drive.

• When you conﬁgure your HP D2D Backup System with a standalone tape drive, 200 GB of

physical disk space is made available for that tape drive. This is the equivalent of a permanentlymounted 200 GB tape cartridge, which cannot be unloaded. Tape spanning is impossible, so the data to be backed up must not exceed 200 GB.

• When you conﬁgure your HP D2D Backup System with a tape autoloader, up to 200 GB of

physical disk space can be made available for each conﬁgured slot. This is the equivalent of an autoloader with multiple slots, each containing a 200 G B cartridge. Both tape spanning and, more importantly, ﬂexible tape rotation strategies are possible.

Hos

Each emulated tape device is uniquely mapped to an individual host; this is the network server or PC that you wish to back up.

• Multiple servers may not back up to a single tape device.

Figure 2 on page 17 shows a conﬁguration with a single host. Figure 3 on page 18 shows a

conﬁguration with six hosts. See “Connecting and installing the HP D2D Backup System”onpage23for more example conﬁgurations.

• By default, the host sees only one device, the autoloader that has been conﬁgured for it during

installation. Data from each host goes to its corresponding autoloader.

• Each backup device is visible only to the host for which it has been conﬁgured.

• A host may have multiple devices conﬁgured for it on the HP D2D Ba ckup System, but this means

fewer hosts m ay be connected (not illustrated, see Figure 34 on page 61 for an example of one host with two devices).

Import/Export and Copy

If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an important requirement for Disaster Recovery strategies. The main difference between copy and export is that copied data remains on the HP D2 D Backup System; exported data is removed from it, but can be imported easily when required. These functions are grouped under the Tape Attach section of the Web Interface. Please see “Export, impor t and copy to an attached tape drive” on page 83 for more details about working with Tape Attach.

iSCSI

The HP D2D Backup System is an iSCSI device. This means that the HP D2D Backup System plugs directly

he network, but it presents devices as directly-attached SCSI autoloaders to host machines. In order

into t to function, it requires an iSCSI initiator. On Windows systems, this is normally downloaded by the Installation wizard, as described in “Connecting and installing the HP D2D Backup System” on page 23. For more information about iSCSI, see “Advanced installation” on page 45. Linux users should also refer to the “Linux Conﬁguration Guide” on the HP StorageWorks Tape CD-ROM for more information.

Mail slots (import/export elements)

A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used speciﬁcally to import and export cartridges. They are sometimes called import/export elements by backup applications. Backup applications that support this feature move cartridges from the mail slot when the user runs an Export job, and look for cartridges in the mail slot when the user runs an Import job.

RAID

RAID stands for Redundant Array of Inexpensive (or Independent) Devices, which is a data storage scheme that divides data among multiple hard drives, increasing data reliability and throughput. The HP D2D Backup System is a RAID5 device, which offers the best combination of data protection and capacity. It has four hard disks, but if one of the disks fails, no data is lost and the HP D2D Backup System continues to operate correctly. (The failed disk should be replaced as soon as p ossible, as described in “Replacing the hard disk” on page 115.)

Storage capa

Physical storage

The physical storage capacity of the HP D2D Backup System 130 is 3.0 TB (3000 GB), of the HP D2D Backup System 120 is 2.0 TB (2000 GB) and of the HP D2D Backup System 110 is 1 TB (1000 GB). However, in order to ensure a high level of data integrity, the disks use RAID 5 protection. This reduces the available capacity but ensures that, in the event of a single disk failure in the device, there will be no data loss.

Actual storage capacity is approximately:

• 2.25 TB for the HP D2D Backup System 130

• 1.5 TB for the HP D2D Backup System 120

• 750 GB for the HP D2D Backup System 110

You cannot add physical disk space, but you may be able to create some space. Options for creating space, if the disks start to get full, are:

• Review your backup jobs to see if you can reduce the size of backup or retention time.

• Use the backup application job settings to overwrite or erase data.

• Export cartridges to physical tape.

Actual storage used

The default maximum car tridge size is 200 GB, but the HP D2D Backup System only allocates spac e as it is required for backup. Individual backup jobs rarely use a whole cartridge and you are unlikely to use all the available disk capacity. However, when conﬁguring the HP D2D Backup System for extremely ﬂexible tape rotation schemes, it may be necessary to exercise a little care. You should take the following factors into consideration to ensure that you do not over-commit physical storage space:

• The nu

with 24 slots. You could not ﬁll all of these slots with the physical disk capacity available.

each

Considerations when conﬁguring cartridges and slots

Tape rotation strategies

Tape rotation strategies determine when backups are run, the number of cartridges that a re required and how they are reused. The HP D2D Backup System is a very ﬂexible device that can e asily be incorporated into most tape rotation strategies. If your organization does not yet have a tape rotation strategy in pla ce, see “Backup scenarios using the HP D2D Backup System” on page 55 for example conﬁgurations.

Compression

The HP D2D Backu moving data from the HP D2D to physical tape, bear in mind that HP StorageWorks tape drives do apply compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seem s to utilize less space.

Some users may the storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly attached to the HP D2D Backup System. This ensures that the user knows exactl

Software installation, discovery and conﬁguration

There are three stages to installation:

• Install all the required drivers

• Discover the HP D2D Backup System on the network, give it a name and, if DHCP is not

supported, assign network settings

• Create a base conﬁguration to get started

Dynamic (DHCP) addressing is enabled by default on the H P D2D Backup System. If your network supports DHCP, all the required network parameters will be assigned automatically. If your net work uses static IP addressing, you will need to assign network settings manually (IP address, subnet mask and gateway).

For Windows users, the recommended way to set up the HP D2D Backup System network is to run the Installation wizard from the HP StorageWorks CD-ROM, as described in “Installation wizard” on page 39.

Linux users should download the latest patches for their operating system and refer to the “Linux Conﬁguration Guide” on the HP StorageWorks CD-ROM for con ﬁ guration instructions.

This chapter is relevant for users installing on a Windows host. If you are installing on a Linux system, please refer to the “Linux Conﬁguration Guide” on the HP StorageWorks Tape C D-ROM.

In this chapter:

•

“Before you install the ﬁrst host”onpage39

•

“Run the Installation wizard” on page 40

If you are installing on a Windows system, the Installation wizard is the recommended way to set up a host machine to work with the HP D2D Backup System, particularly if you are conﬁguring the host for the ﬁrst time. The wizard automatically conﬁgures all the software components needed to connect and use the HP D2D Backup System. It should be run on all hosts that are to be backed up to the HP D2D Backup System.

If you are not using the Installation wizard to install on a Windows system, please see “Advanced installation”onpage45.

• “Linux iSCSI initiator” on page 51

• “Manual driver installation” on page 51

Using DHCP to discover the HP D2D Backup System

If you are connecting the HP D2D Backup System to a network that has a DHCP server, DHCP addressing is enabled by default. The IP address and other network settings are assigned automatically when you connect the HP D 2D Backup System to the network. You only need to know the name of the HP D2D Backup Sys the forma

tem to complete the installation and create an 8–slot autoloader conﬁ guration. The name is in

t D2DBS-<serial number> and can be found on the label on the front of the unit.

Once the HP D2D Backup System has been discovered on the network, you must conﬁgure the Microsoft iSCSI Initiator on the host, so that the autoloader devices on the HP D2D are visible to the backup application. See “Micr osoft iSCSI Initiator” on page 46.

Using the Discovery Engine to discover the HP D2D Backup System

If your network does not have a DHCP server, the Discovery Engine allows you to locate the HP D2D Backup System on your network and assign network settings, such as the IP address. It is the recommended way to locate and conﬁgure the HP D2D Backup System on your network, if you are using static IP addressing. It also allows you to select your required base conﬁguration and specify the number of slots for an autoloader.

Emulation type is totally independent from cartridge size. The HP D2D Backup System allows you to pick whatever cartridgesizeyoulike(upto800GB).

7 Backup scenarios using t he HP D2D Backup System

The HP D2D Backup System combines all the traditional beneﬁts of tape technology, such as support for complexmediarotationschemes,withtherapidbackupandrestoretimethatisonlypossiblefromdisk.

Backup applications allow users to conﬁgure rotation schemes that use tapes for speciﬁcdays,weeks and months of a year, often applying different retention policies to each backup job. Such rotation schemes require an autoloader as the backup device.

Using a tape autoloader conﬁgured on your HP D2D Backup System enables you to use the same tape rotation schemes that you would use with physical tape. To your backup application the tape autoloader conﬁguredontheHPD2DBackupSystemisaphysicaltapeautoloaderdeviceandyoucanconﬁgure backup jobs from your backup application in exactly the same way as you would for tape. But you beneﬁt from much faster performance because you are writing to or reading from disk.

Read this chapter for example backup scenarios. It will also give you a clearer understanding of how you can calculate the number of slots required and ensure that disk space is used effectively.

• For the other weekdays, Mond ay to Thursday: carry out incremental backups to capture that day’s

changes (one cartridge for each day) and keep each cartridge for a week before overwriting. Assuming a separate c artridge for each day’s incremental backup, another four autoloader slots are required.

• On the last day of the month:

• From the host (1) carry out a full backup to one cartridge to capture the month’s work ready

• Tape drive: which indicates that a physical cartridge is inserted in an attached

tape drive and is ready for import.

A bar code is an 8–digit, alphanumeric, unique identiﬁer for a cartridge within the HP D2D Backup System. Bar codes are shared with the backup application, if requested. The backup application may also choose to assign its own internal identiﬁer to the cartridge but, if it does so, it cannot assign this identiﬁer to the Cartridge bar code.

Bar codes are generated automatically but may be edited by the user. If you choose to edit the bar code:

• It must be unique and must not start with the letters “CLN” or “DG” because

these are reserved designations for cleaning and diagnostic cartridges.

• It should be a minimum of 4 characters. Valid ASCII characters are A-Z, a-z,

WARNING !

Once you have started to upgrade the ﬁrmware, it is important that you allow it to complete. Do not attempt to cancel the upgrade process, or power off the machine.

NOTE:

The tape drive is reported to your b a ckup application (and Windows Device Manager) as an LTO-3 device. This is the default behavior of the tape drive and there is no need and no way to change it on the HP D2D Backup System. In earlier versions of the HP D2D Backup System ﬁrmware, the tape drive was reported as an LTO-2 device. Once you upgrade to the latest version of the ﬁrmware, the backup application continues to identify existing backup devices as LTO-2 and identiﬁes new tape devices as LTO-3, but this has absolutely no impact on how the device behaves or functions. If you delete existing devices (LTO-2) and create new ones; the new ones will be LTO-3. (It is important not to confuse emulation type with cartridge size. Emulation type is totally independent from cartridge size. The HP D2D Backup System allows you to pick whatever cartridge size you like, up to 800 GB.)

9 Export, import and copy using an attached tape drive

If your organization’s backup strategy also requires the ability to archive backed-up data for offsite storage, there are two ways of achieving this:

• Attach an HP Ultrium tape drive directly to the HP D2D Backup System and use the copy,

export and import facilities in the Web Management Interface to transfer data manually or to schedule jobs.

• Attach a supported tape drive to a host machine on the storage network. If your backup

application supports the copying of data between devices, you can then use the backup application to move data from the HP D2D Backup System to physical tape. This option is described in “Copy using a tape drive attached to the host” on page 99.

Cartridge copy

The backup application on the host is used to back up data to a cartridge on the autoloader device (or to a standalone tape drive device) in the HP D2D Backup System. The Web Management Interface on the HP D2D Backup System is used to Copy the cartridge from the HP D2D Backup System to the attached tape drive, leaving the data on the HP D2D Backup System so that it is available for quick restore.

Figure 36 C artridge copy

WhyusetheCopyfunctionality?

Copy creates two instances of the same cartridge; one stored on the HP D2 D, the other on physical tape. Logically these are the same cartridge and the backup application has no awareness that there are two copies. If da ta from this cartridge is required for restore, the backup application will always restore the data from the HP D2D if it is available. The physical cartridge is, therefore, an additional copy that will be required only if the HP D2D is not available.

When would Copy be used?

Cartridge copies are likely to be appropriate when the user wishes to use the HP D2D Backup System for all foreseeable restore processes but requires an additional offsite copy for insurance or data security purposes. This may mean that weekly, monthly and yearly cartridges are copied. Weekly and monthly physical cartridges may be rotated; the cartridges on the HP D2D Backup System are overwritten after a period of time. Yearly cartridges may be kept indeﬁnitely. Clear labeling of the cartridges in this case is essential because the backup application may overwrite the cartridge on the HP D2D Backup System and, therefore, lose any knowledge of the existence of the physical tape cartridge.

When

is it necessary to restore from a copied cartridge?

e are three situations where it may be necessary to restore from the copied cartridge:

Ther

• The cartridge stored in the autoloader device on the HP D2D is overwritten (accidentally) by the

backup application. The backup application database is updated to reﬂect the new contents of the cartridge and all knowledge of the old data is lost. If the backup administrator becomes

re that this has happened, it is possible to import the physical cartridge back into the HP D2D

awa

tem, from where its data can be "imported" back into the application database for restore, if

sys required. In this case, because the backup application has overwritten the database entry for the cartridge, some external knowledge of what is on the copied cartridge is required in order to be able to decide whether the data on the copied cartridge is useful.

ewholeHPD2DBackupSystemoracompleteautoloaderontheHPD2Disaccidentally

• Th

removed from the Web Management interface. The physical copy of the cartridge is the only copy now in existence. The backup application is still aware of the cartridge’s existence because it was not aware of the loss of the D2D system. The backup administrator has two options; if there is no required restore at this point, the administrator can deploy a new HP D2D system or create

new autoloader on the existing D2D and then import any copied cartridges back into the new

D2D Backup System

device for use with restores at a later date. If a restore is urgently required, the administrator can put the copied cartridge into a physical tape drive attached to the host and restore directly from that. In either case, the backup application is aware of the cartridge’s existence.

• Both the D2D system and the host are lost. In this case, the physical cartridge copy (as long as it

was a full system backup) can be used for disaster recovery onto new or repaired server hardware using a tape device attached to the host server.

Disadvantages of Copy

1. Data is left o

cartridge.

2. It is possible for the backup application to overwrite the cartridge on the HP D2D Backup System

and thus b ecome unaware of the data that has been copied to the physical cartridge.

Cartridge export

The backup application on the host is used to back up data to a slot on the autoloader device (or to a standalone tape drive device) in the HP D2D Backup System. It is also used to move the data from the slot into the mail slot. This creates an empty slot where the data was moved.

The Web interface on the HP D2D is used to Export cartridge data from the mail slot on the HP D2D Backup System to the attached tape drive. After a successful export, the data is removed from the HP D2D Backup System and the mail slot becomes empty. (If the export fails, the data remains in the mail slot.) Export removes the data and frees up disk space on the HP D2D Backup System and is useful for long term archival (for example in a yearly tape in a rotation scheme). If restore is needed, data can be imported (or moved back) into the HP D2D Backup System.

CAUTION:

Do not export cartridges that the backup application uses on a frequent basis as part of a rotation strategy because it will not be able to write to the empty slot.

HP StorageWorks D2D Backup System

Figure 37 Cartridge export

Why use the Export functionality?

ThemainreasonforusingExport is to create more space on the HP D2D Backup System. If space is not an issue, Copy is the recommended method for creating offsite backups, because it is controlled solely from the Web Management Interface and will not impact any tape rotation strategy. Export involves use of the backup application. It is directly analogous to moving a cartridge in a physical autoloader to a mail slot (import/export element) so that the backup administrator can take it offsite or put it into a ﬁresafe. Only a single copy of the car tridge exists. It is on physical tape and no longer on the cartridge in the HP D2D Backup System. The backup application is fully aware that the cartridge location is now offsite, so cannot overwrite it without explicitly asking for the cartridge to be moved back into the autoloader.

Step 2

Use HP D2D Web Management Interface to export to tape drive.

The main advantage of Export is that it frees up disk space on the HP D2D Backup System. However, care must be taken to ensure that future backups do not fail. For example, if a weekly backup tape is

rted", it will not be available for append or overwrite the next time it is required. Depending on

"expo

ckup application conﬁguration it may be possible to simply create a new blank cartridge in the

nece

When would Export be used?

Cartridge exports are likely to be used when the user wishes to free up space on the HP D2D Backup System by exporting to physical tape a car tridge that is used infrequently. For example, if a rotation scheme uses twelve monthly tapes, it is safe to export a monthly tape from two months ago because it will not now be required (except for infrequent restores) for another ten months. The same applies to yearly tapes which may never be required again as they are kept forever.

en would I restore from an exported cartridge?

storing from an "exported" cartridge has a higher likelihood than from a copied cartridge, because

he data no longer resides on the HP D 2 D Backup System. If a restore from an "exported" cartridge is

equired, the backup application will ask for the cartridge to be re-imported into the HP D2D before it can

e used for restore. Exported cartridges may also be used for disaster recovery, as with copied cartridges.

Disadvantages of Export

1. Restores may take longer if a physical cartridge is required for the restore.

2. Backup applications may require the exported cartridge for the next job in their rotation scheme.

pull-down list, the required verify/compare option and whether the physical cartridge should be unloaded after the operation completes. Click Start.

NOTE:

A Full Verify reads the data back after copy and compares it byte-by-byte with the original. A Quick Verify also reads back the data, but only ensures that i t can be read. It may save some time if another tape device on the HP D2D Backup System is being accessed at the same time as the copy operation. No Verify is the fastest option.

3. The process warns you that when importing cartridge data to a tape drive device on the HP D2D

that contains a non blank cartridge, the data on the cartridge will be overwritten. You must click OK to continue.

4. To view job progress information and any error messages, select the Status navigation topic.

5. Once the import has completed successfully, the cartridge is in the mail slot. Use the backup

application to move the data back into the autoloader slots. Backup applications have a number of terms to describe this action, such as insert. Refer to the documentation supplied with your backup application for further details.

Status (Tape Attach)

This page displays the status of any current tape import/export or copy operations.

If a job is in progress, it shows cartridge barcode and target tape drive details and relevant p rogress bars. The percentage completion is the amount of progress for all relevant activities in the operation, such as export and verify (if requested).

NOTE:

If no operations are currently in progress, a link will be provided to the Tape Attach Job History page.

To cancel a job

To cancel a job in progress, click Cancel .Youareaskedtoconﬁrm that you wish to cancel the job.

If a job is canceled during the copy, export or import phase, this cancels the transfer of data.

• For export and copy jobs, the data remains in the m ail slot or slot on the HP D2D Backup System

and the physical tape on the tape drive is rewound and erased.

• For import jobs, the data remains on the attached tape d rive.

If a job is canceled during the verify phase, the data has already been moved and it is only the verify process that is canceled.

If an error occurs

Errors may o ccur if there is a tape read/write media problem, if there is not enough capacity on the physical cartridge or if there is a verify error. Errors may also occur if the backup application accesses the cartridge that is being exported/imported or copied.

Errors are reported as a dialog box on this page, which requires you to click OK to clear it.

If an error occurs during export or copy, you do not lose any data. The original data remains unaltered in its original location on the HP D2D Backup System.

Schedule (Tape Attach)

This page allows you to create, edit and delete schedules for export and copy operations.

D2D Backup System

• Four types of schedule are allowed: daily, weekly monthly by day and monthly by week.

• Up to 12 schedules may be created.

When an export or copy scheduled job is run, it automatically overwrites the car tridge in the tape d rive. If the cartridge is not blank, there is no warning and no record in the job log.

NOTE:

The backup application is not automatically updated with any schedules created on the HP D2D Backup System. The two are independent of each other. If you want the backup application schedules to work in conjunction with a schedule on the HP D2D Backup System, you must co-ordinate them manually.

To create a schedule

1. Select Schedule from the Tape Attach section of the navigation side bar.

2. A scrollable list of existing schedules is displayed together with details of the next scheduled tape job.

3. From the pull-down lists below this list, select:

• The HP D2D Backup System device (autoloader or tape drive) that contains the data for which you want to create a scheduled job.

• The frequency of the job: daily, weekly, monthly by day or monthly by week .

4. Click Create. Appropriate scheduling parameters for the backup device and job frequency are

displayed below.

NOTE:

The Create button is not present if you have already created 1 2 schedules. You must edit or delete existing schedules if you want to create new ones.

Compression

The HP D2D tape driv will require less space o n a physical 200 GB tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seems to utilize less space.

The capacity quoted for physical media assumes that the tape drive will be able to compress your data and reduce the ﬁle sizes by 50%, but this can be achieved only if your data is not already compressed. For exa text ﬁles, high-resolution graphics are not. Most users have a mixture of compressed and uncompressed data and seldom achieve 50% compression.

Some us the storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly at tached to the HP D2D Backup System. This ensures that the user knows

Requirement

If you wish to you need:

• A separate tape device, such as an HP StorageWorks Ultrium 460 or 448 tape drive, that can

be connecte

• A backup application, running on the host, that allows you to copy data from the cartridge on

your HP D2D Backup System to the physical cartridge.

NOTE:

It is not po supported on tape drives that are connected directly to the HP D2D Backup System. See “Export, import and copy to an attached tape drive”onpage83

ssible to export and import data using this method. Export and import are only

Tape drives supported

The HP StorageWorks Ultrium 448 or 460 tape drive is the ideal device for all copying processes because the physical cartridge size matches the maximum conﬁgured cartridge size on the HP D2D Backup System. However, by spanning across several tapes, you can also use a tape drive with a lower capacity, such as an HP StorageWorks DAT 72 tape drive. If your backup application will not allow you to span tapes, you may want to use the Web Management Interface to reduce the maximum conﬁgured cartridge size on the HP D2D Backup System. However, you must do this when you ﬁrstcreatethe autoloader or additional slots and before you have used the autoloader in any way with your backup application. See “To edit maximum size” on page 70.
