2.1 Ownership and Title. As between the parties, Legato, and its licensors, own and shall retain all right, title, and interest in and to: (i) the Software including all intellectual property rights embodied therein; (ii) all of the service marks, trademarks, trade names, or any other designations associated with the Software; and (iii) all copyrights, patent rights, trade secret rights, and other proprietary rights relating to the Software.

2.2 Software Activ at ion. Legato employs Enabler Codes and Authorization Codes that enable the use of the Software. The Software is shipped in a "Media Kit" which consists of object code software on CD-ROM and an Enabler Code for initial activation of the Software or the Software and Enabler Code may be delivered electronically. Once Legato receives confirmation from Licensee that the Enabler Code is installed and is provided with the host ID information, Legato will provide the Authorization Code to Licensee.

2.3 Administration of Software. Legato may include on the media with the Software additional computer programs which are not currently licensed for use by Licensee and to which the Enabler Code or Authorization code will not permit access. Inclusion of such additional computer programs in no way implies a license from Legato and access or use of such programs is strictly prohibited unless Licensee procures the right to use any such program and the applicable Enabler Code is provided thereto.

3. LICENSE GRANT

3.1 Grant. Legato grants to Licensee a nonexclusive, nontransferable, nonsublicensable, perpetual, unless terminated in accordance with the provisions of this Agreement, license (the “License”) to (i) use the Software installed in accordance with the Documentation and only on the licensed computer solely for its own internal operations; and (ii) move the Software temporarily in case of computer system malfunction. The License granted under this Agreement does not constitute a sale of the Software or any portion or copy of it. Licensee may not use the Softwar e on mor e than one computer system unless otherwise specifically authorized by an explicit Software product, or additional licenses for additional computers are purchased. Rights not expressly granted are reserved by Legato. Where the Software is provided to Licensee at no charge for evaluation purposes only, the License granted is limited to a continuous thirty (30) day period,

commencing with the acceptance of this Agreement (the "Evaluation Period"). At the conclusion of the Evaluation Period, Licensee agrees to destroy the Software and certify its destruction to Legato, in writing, within ten (10) days, or shall return the Software to Legato or purchase a perpetual license.

3.2 Copies. Licensee may make copies of the Software provided that any such copy is: (i) created as an essential step in utilization of the Software on the licensed computer and is used in no other manner; or (ii) used for archival purposes to back up the licensed computers. All trademark and copyright notices must be reproduced and included on such copies. Licensee may not make any other copies of the Software.

3.3 Restrictions on use. Licensee shall not, and shall not aid, abet, or permit any third party to: (i) decompile, disassemble, or otherwise revers e engineer or attempt to reconstruct or discover any source code or underlying ideas or algorithms of the Software by any means whatsoever; (ii) remove any identification, copyright, or other notices from the Software; (iii) provide, lease, lend, use for timesharing or service bureau purposes; (iv) create a derivative work of any part of the Software; or (v) develop methods to enable unauthorized parties to use the Software. If EC law is applicable, the restrictions in Section 3.3 (i) are limited so that they prohibit such activity only to the maximum extent such activity may be prohibited without violating the EC Directive on the legal protection of computer programs. Notwithstanding the foregoing, prior to decompiling, disassembling, or otherwise reverse engineering any of the Software, Licensee shall request Legato in writing, to provide Licensee with such information or assistance and Licensee shall refrain from decompiling, disassembling, or otherwise reverse engineering any of the Software unless Legato cannot or has not complied with such request in a commercially reasonable amount of time.

3.4 Purchase Orders. Nothing contained in any purchase order, acknowledgment, or invoice shall in any way modify the terms or add any additional terms or conditions to this Agreement.

3.5 Updates. This section applies if the Software acquired is an update to the original Software (the “Update”). An Update does not constitute a legally licensed copy of the Software unless purchased as an Update to a previous version of the same Software. The Update may only be used in accordance with the provisions of this Agreement. The Update, together with the original Software, constitutes one (1) legally licensed co py of the Software.

3.6 Evaluatio n License. This Section applies if the Software is being used for an initial thirty (30) day evaluation period. The license is valid only for a period of thirty (30) days from the delivery of the Software, and is designed to allow Licensee the right to evaluate the Software during such period. In the event that Licensee desires to enter into a longer-term license agreement with Legato, Licensee shall obtain an appropriate Enabler and Authorization Code in accordance with Section 2.2 above, upon payment of applicable fees, which authorizes use of the Software after such evaluation period, but only subject to all of the terms and conditions of this Agreement. In the event Licensee determines not to enter into a licensing transaction with Legato at the end of such thirty (30) day evaluation period, then Licensee’s rights under this Agreement shall terminate automatically and Licensee shall promptly return to Legato or destroy all copies of the Software and so certify to Legato.

4. MAINTENANCE AND SUPPORT

4.1 Legato has no obligation to provide support, maintenance, upgrades, modifications, or new releases under this Agreement. Legato may provide such services under separate agreement.

5. LIMITED WARRANTY

5.1 Media and Documentation. Legato warrants that if the media or documentation are damaged or physically defective at the time of delivery of the first copy of the Software to Licensee and if defective or damaged product is returned to Legato (postage prepaid) within thirty (30) days thereafter, then Legato will provide Licensee wi th replacem ents at no cos t.

5.2 Limited Software Warranty. Subject to the conditions and limitations of liability stated herein, Legato warrants for a period of thirty (30) days from the delivery of the first copy of the Software to Licensee that the Software, as delivered, will materially conform to Legato’s then current published Documentation for the Software. This warranty covers only problems reported to Legato during the warranty period. For customers outside of the United States, this Limited Software Warranty shall be construed to limit the warranty to the minimum warranty required by law.

5.3 Remedies. The remedies available to Licensee hereunder for any such Software which does not perform as set out herein shall be either repair or replacement, or, if such remedy is not practicable in Legato’s opinion, refund of the license fees paid by Licensee upon a return of all copies of the Software to Legato. In the event of a refund this Agreement shall terminate immediately without notice

6. TERM AND TERMINATION

7. DISCLAIMER AND LIMITATIONS

ALL SOFTWARE IS PROVIDED “AS IS” AND LEGATO DOES NOT WARRANT THAT THE SOF TWARE WILL MEET ANY REQUIREMENTS OR THAT THE OPERATION OF SOFTWARE WILL BE UNINTERRUPTED OR ERROR FREE. ANY LIABILITY OF LE GATO WITH RESPECT TO THE SOFTWARE OR THE PERFORMANCE THEREOF UNDER ANY WA RRA N TY, NEGLIGENCE, STRICT LIABILITY OR OTHER THEOR Y WILL BE LIMITED EXCLUSIVELY TO THE REMEDIES SPECIFIED IN SECTION 5.3 ABOVE. Some jurisdictions do not allow the exclusion of implied warranties or limitations on how long an implied warranty may last, so the above limitations may not be applicable.

8. LIMITATION OF LIABILITY

8.1 Limitation of Lia bility. EXCEPT FOR BODILY INJURY, LEGATO (AND ITS LICENSORS) WILL NOT BE LIABLE OR RESPONSIBLE WITH RESPECT TO THE SUBJ EC T MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY, OR OTHER LEGAL OR EQUITABLE THEORY FOR: (I) ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, HOWEVER CAUSED AND WHETHER OR NOT ADVISED IN ADVANCE OF THE POSSIBILITY OF SUCH DAMAGES; OR (II) DAMAGES FOR LOST PROFITS OR LOST DATA; OR (III) COST OF PROCUREMENT OF SUBSTITUTE GOODS, TECH NOLOGY , SER VICES , OR RIGHTS; OR FOR AMOUNTS IN EXCESS OF THOSE RECEIVED BY LEGATO FOR THE PARTICULAR LEGATO SOFTWARE THAT CAUSED THE LIABILITY. Because some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, Legato's liability in such jurisdictions shall be limited to the extent permitted by law.

9. MISCELLANEOUS

9.1 Governing Law. This Agreement shall be governed by the laws of the State of California, as applied to agreements entered into and to be performed entirely within California between California residents, without regard to the

principles of conflict of laws or the United Nations Convention on Contracts for the International Sale of Goods.

9.2 Government Restricted Rights. This provision applies to Software acquired directly or indirectly by or on behalf of any government. The Software is a commercial softwar e pro duct, licensed on the open market at market prices, and was developed entirely at private expense and without the use of any government fund s. All Software and accompanying Documentation provided in connection with this Agreement are “commercial items,” “commercial computer software,” and/or “commercial computer software documentation.” Any use, modification, reproduction, release, perf orm ance, display, or disclosure of the Software by any government shall be governed solely by the terms of this Agreement and shall be prohibited except to the extent expressly permitted by the terms of this Agreement, and no license to the Software is granted to any government requiring different terms. Licensee shall ensure that each copy used or possessed by or for any government is labeled to reflect the foregoing.

9.3 Export and Import Contr ol s . Regardless of any disclosure made by Licensee to Legato of an ultimate destination of the Products, Licensee w ill not directly or indirectly export or transfer any portion of the Software, or any system containing a portion of the Software, to anyone outside the United States (including further export if Licensee took delivery outside the U.S.) without first complying with any export or import controls that may be imposed on the Software by the U.S. Government or any country or organization of nations within whose jurisdiction Licensee operates or does business. Licensee shall at all times strictly comply with all such laws, regulations, and orders, and agrees to commit no act which, directly or indirectly, would violate any such law, regulation or order.

9.5 Sole Remedy and Allocation of Risk. Licensee's sole and exclusive remedies are set forth in this Agreement. This Agreement defines a mutually agreed-upon allocation of risk, and the License price reflects such allocation of risk.

9.6 Equitable Relief. The parties agree that a breach of this Agreement adversely affecting Legato’s intellectual property rights in the Software may cause irreparable injury to Legato for which monetary damages may not be an adequate remedy and Legato shall be entitled to equitable relief in addition to any remedies it may have hereunder or at law.

9.7 No Waiver. Failure by either party to enforce any provision of this Agreement will not be deemed a waiver of future enforcement of that or any other provision, nor will any single or partial exercise of any right or power hereunder preclude further exercise of any other right hereunder.

9.8 Severability. If for any reason a court of competent jurisdiction finds any provision of this Agreement, or portion thereof, to be unenforceable, that provision of the Agreement will be enforced to the maximum extent permissible so as to effect the intent of the parties, and the remainder of this Agreement will continue in full force and effect.

10. ENTIRE AGREEMENT

10.1 This Agreement sets forth the entire understanding and agreement between the parties and may be amended only in a writing signed by authorized representatives of both parties.

Disaster Recovery Guide

The Legato NetWorker Disaster Recovery Guide, Release 7.0 provides step-by-step instructions for recovering from a disaster on supported NetWorker 7.x client and server platforms.

This chapter includes the following sections:

• “What Is a Disaster?” on page 19

• “Disaster Recovery Guide Overview” on page 20

What Is a Disaster?

For the purpose of this guide, a disaster is any situation in which the day-to-day access to data (for example, working files, software programs, or system files) is disrupted. A disaster can also damage network components, such as data, devices, hardware, media, and software.

A disaster can result from any of the following:

Chapter 1: Introduction

• Computer viruses that can corrupt data

• Hardware and software failures

• Infrastructure interruptions, inconsisten c ie s, or loss of services, such as

communication or network con nections The degree of loss during a disaster can range from one or more files to an

entire computer system. The severity of the disaster determines the procedures necessary to recover data.

Note: The term autochanger refers to a variety of backup devices: autoloader, carousel, datawheel, jukebox, library, and near-line storage.

Chapter 2: Preparing for a Disaster

This chapter contains informat ion on preparing f or a disaster. This chapter includes the following sections:

• “Preparing for Disaster ” on page 21

• “Gathering the Key Information” on page 22 If you are viewing the online version of this guide, print out a hard copy and

store it in a safe location.

Preparing for Disaste r

You should back up important data on a scheduled basis. The more time and effort you invest in incorporating, maintaining, and testing a backup solution, the better prepared you are in the event of a disaster.

Ensure that servers are backed up regularly using a backup group. Otherwise, a bootstrap is not saved (backups performed using the command line or the NetWorker User program do not save the NetWorker server bootstrap). You should also use a local backup device on the server to back up the server’s bootstrap.

Always perform a scheduled backup of the NetWorker server after upgrading to a new rele ase of NetW or ker software . This ensures th at an upgraded version of the bootstrap is saved.

The bootstrap information can be printed from the savegrp.log file, which is located in the nsr directory. For instructions on how to configure the NetW o rker software to send bootstrap information dir ectly to a printer or to a specified e-mail address, refer to the appropriate Administrator’s Guide. If the bootstrap is backed up to a pool other than the preconfigured pools, save the name of the pool along with the bootstrap.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

Gathering the Key Information

To recover from network-related disasters, you must have access to key information related to each computer that needs protection. Maintain a copy of this information on-site for easy access by th ose assigned to perform disaster recovery.

Important: Having the correct information on hand in case a disaster occurs is a key element in recovering from a disaster as quickly as possible.

Enact strict guidelines regarding the access, maintenance, and usage of this information, and maintai n the information in an on-site location that is the most resistant to disaster.

Gathering the Key Information

Maintain accurate records for each hardware, software, network, device, and media component.

Hardware Information

Maintain the following up-to-date information regarding computer hardware:

• Filesystem configuration

• Fully qualified domain names, IP addresses, and hostnames

• Computer properties: –Hostname – DNS domain name – Superuser password

• Device and SCSI drivers

• Boot files required for booting the kernel. For example: – /unix – /boot – /etc/default/boot – /stand/vmunix

Important: To determine which boot files should not be overwritten during a recovery refer to the appropriate operating system documentation.

How to Install and Configure the UNIX Operating System

When recovering a UNIX operation system, you must reinstall the same version of UNIX and any patches that were in use prior to the disaster. Then configure only those features that enable the computer to communicate over the network. You can recover the remaining operating system configuration settings after reinstalling the NetWorker software.

You can recover the UNIX operating system back to the original computer or to a different computer.

To recover the operating system, complete the following tasks:

• “Task 1: Install the Operating System” on page 30

• “Task 2: Configure the Operating System” on page 30

• “Task 3: Configure the Devices and Test the Operating System” on

page 31

Important: Do not install the operating system from a UNIX X-Windows session. Instead, recover the operating system in single-user mode from the system console.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

Prerequisites

Task 1: Install the Operating System

To install the operating system:

1. Instal l the same version and patch level of the UNIX operating system. Specify the same installation locations that were used in the predisaster installation of the operating system . For installation information, refer to the appropriate UNIX documentation.

If you want to upgrade the operating system, recover the predisaster version of the operating system before performing any upgrades.

2. Re-create all of the filesystems that were previously on the computer. The filesystems must be:

• The same filesystem type.

• At least the same partition size as the original to hold all of the data

that was previously backed up.

At a minimum, configure the root volume group and kernel parameters, such as asynchronous I/O. If the resources are available, reconstruct nonroot volume group filesystems and logica l volumes.

Task 2: Configure the Operating System

To configure the operating system:

1. Configure the network exactly as it was before the disaster. If you do not, the NetWorker software will treat the computer as a new computer. If the computer has a different host ID, you must reregister the NetWor ker software. For information on registering the NetWorker software, refer to the appropriate Legato NetWorker Installation Guide.

2. If you are recovering the operating system to a differ ent computer, assign the same hostname to the new computer. Otherwise, you will not be able to recover the NetWorker inde xes associated with the original computer.

3. Configure the date and time as they were before, including the time zone.

4. Install any additional UNIX components or services before recovering the computer’s data.

5. Reboot the computer.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 3: UNIX Disaster Recovery

Task 3: Configure the Devices and Test the Operating System

To configure the devices and test the operating system:

1. Configure any devices the NetW orker software requires, for example SCSI pass-through devices for autochangers. For information about configuring devices, refer to the Legato NetWorker Administrator’s Guide, UNIX Version.

2. Te st that th e:

• Name to Address resolution and TCP/IP are functioning properly.

To test these, run ping on the server to reach a client, and then run ping on a client to reach the server.

• Operating system is functioning properly.

• Tape drive is functioning properly. To test this, run the mt

commands.

• Operating system recognizes devices. If the operating system is not

recognizing devices, you might need to: – Load the SCSI driver. – Install the device driver software. – Modify the device configuration fil es to enable the computer to

communicate with the device during recovery. For details on modifying the device configuration files, refer to the Legato NetWorker Administrator’s Guide.

3. Ensure that the block size mode for tape devices used with NetWorker is set to variable. Otherwise, data recovery may fail. The procedure for setting the device block size varies depending on your operatin g system. For example, to set the tape device block size on an AIX system:

a. Open the IBM System Management Interface Tool (SMIT) and select

b. Select Tape Drive.

c. Select Change/Show Characteristics of a Tape Drive. This brings up a

uses.

Completing the Recovery Process

To complete the recovery process after installing and configuring the operating system, use the following procedures, depending on the type of NetWorker computer you are recovering. These procedures describe how to recover the NetWorker software as well as the computer’s application and user data:

• “Recovering a NetWorker Server” on page 32.

• “Recovering a NetWorker Storage Node” on page 40.

• “Recovering a NetWorker Client” on page 43.

Recovering a NetWorker Server

The following sections provide information on recovering a NetWorker server:

• “Prerequisites” on page 32

• “How to Reco ver a NetWorker Server” on page 32

Prerequisites

Before you can recover the NetWorker server, be sure that the UNIX operating system is installed on the computer. For information about reinstalling the UNIX operating system, see “Installing and Configuring the UNIX Operating

System” on page 28.

To recover the NetWorker server, you need the following:

• Version and patch level of the NetWorker server software.

• Original directory location to which the NetWorker server was installed.

• NetWorker server installation media.

• Backup or clone volumes containing the NetWorker server bootstrap and

indexes.

• Name of any links to NetWorker directories. An example of a typical link

from a NetWorker directory to a user directory is /nsr to /usr/nsr.

How to Recover a NetWorker Server

This section describes how to recover the NetWorker server back to the original computer.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 3: UNIX Disaster Recovery

Important: If the NetWorker server w as also a Legato License Manager server , the License Manager lictype.res file is not restored when the server is restored. This is because the License Manager files and directories are not considered part of the NetWorker server. After recovering the NetWorker server, you must explicitly recover the License Manager as a client of the NetWorker server.

To recover a NetWorker server, complete the following tasks:

• “Task 1: Install the NetWorker Server Software” on page 33

• “Task 2: Configure NetWorker Device Resources” on page 34

• “Task 3: Locate the Server’s Bootstrap Save Set ID” on page 34

• “Task 4: Recover the NetWorker Server Bootstrap” on page 36

• “Task 5: Rename the NetWorker Server Configuration Files” on page 37

• “Task 6: Recover All Client File Indexes” on page 38

• “Task 7: Recover the Application and User Data” on page 39

• “Task 8: Perform a Test Backup an d Recovery” on page 39

Task 1: Install the NetWorker Server Software

To install the NetWorker server software:

1. Install the same version of the NetWorker server software into its original location. When you install the NetWorker server software, the NetW orker client is also installed. For installation instructions, refer to the appropriate Legato NetWorker Installation Guide.

Note: If you want to upgrade the NetWorker server, first recover the server to its original state, then perform the upgrade.

2. Install any NetWorker patches that were installed prior to the disaster.

3. Re-create any links to the NetWorker directories such as the directories containing NetWorker index and configuration files.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

Prerequisites

To re-create links to NetWor ker directories:

a. Stop the NetWo r ker daemons by entering the nsr_shutdown

command at the command line:

# nsr_shutdown -a

b. Move the files to their original location. c. Create the links from the /nsr directory to the original location.

d. Restart the NetWorker server by first entering the nsrexecd

command and then entering the nsrd command, for example:

# nsrexecd # nsrd

Note: You can also restart the NetWorker server by running the NetWorker startup script for the appropriate platform.

Task 2: Configure NetWorker Device Resources

To configure the NetWorker software:

• Configure the device resources.

– If you want to recover data using a stand-alone device, ensure that a

resource for the stand-alone device exists (this is defined in the /nsr/res directory). If a resource for the stand-alone device does not exist, create it using the NetWorker Administrator program.

– If you want to recover data using an autochanger, ensure that an

autochanger resource exists (this is defined in the /nsr/res directory). If the autochanger resource does not exist, create it using the jbconfig command. For information about using the jbconfig command, refer to the Legato NetWorker Administrator’s Guide.

Reset the autochanger using the nsrjb -vHE command. This command resets the autochanger, ejects backup volumes, reinitializes the element status, and checks each slot for a volume.

If the autochanger does not support the -E option, initialize the element status using sjiielm (on Linux, use ielem).

Inventory the autochanger using the nsrjb -I command. This helps you determine whether the volumes required to recover the bootstrap are located inside the autochanger.

Task 3: Locate the Server’s Bootstrap Save Set ID

The bootstrap contains the media database, the resource database, and the server index.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 3: UNIX Disaster Recovery

Important: If you routinely move NetWorker backup media to an offsite location for safekeeping, and a subsequent file recover operation generates a mount request, the recover operation waits until an operator mounts the request media. To avoid delays when recovering files, use the mminfo -mv command to list the media that is associated with the file you want to recover and to retrieve the media from the offsite storage before starting the recover.

To locate the save set ID of the most recent bootstrap (if you do not already have this information):

1. Insert the most recent media or clone volumes used for scheduled backups into the appropriate device.

2. At the command line, switch to the directory where the NetWorker binaries and executables are located.

3. If you are using an autochanger, insert the first volume of the bootstrap save set into the first drive of the autochanger using the following command:

device_name using the inquire command.

Prerequisites

Task 4: Recover the NetWorker Server Bootstrap

You can use the mmrecov command to recover the NetWorker server bootstrap.

Note: In NetWorker release 6.0 and later, the mmrecov command is only used to recover the NetWorker server’s media database and resource database; the nsrck command is used to recover the server’s client file indexes.

To recover the NetWorker server bootstrap:

1. Use the mmrecov command to recover the NetWorker server’s bootstrap

(media database and resource database). For example:

mmrecov

Output similar to the following appears:

mmrecov: Using madrid.spain.com as server

Important: The mmrecov command overwrites the server’s media database. It does not overwrite the resource database, instead mmrecov recovers it to the resource directory, res.R . For syntax and option informatio n about mmrecov, refer to the Legato Command Reference Guide.

2. If the server has multiple devices configured and enabled, the following message appears. If you receive this message, enter the name of the device you are using for the recovery.

What is the name of the devi ce you pl an on usin g [/dev/rmt/0hbn]? /dev/rmt/0hbn

3. When the following message appears, enter the save set ID for the latest bootstrap. If you are recovering a cloned version of the bootstrap, specify the save set ID associated with the clone.

Enter the latest bootstrap save set ID []: 20076

4. When the following message appears, enter the file number to begin the recovery. If unknown, press [Enter].

Enter starting file number (if known) [0]: 130

5. When the following message appears, enter the first record number to begin the recovery. If unknown, press [Enter].

Enter starting record number (if known) [0]: 0

6. When the following message appears, follow the prompt:

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 3: UNIX Disaster Recovery

Please insert the volume on which save set id 20076 started into /dev/rmt/0hbn.

Once you have loaded the appropriate volume, the following message appears:

Scanning /dev/rmt/0hbn for save set 20076; this might take a while...

NetWorker then scans the volume for the appropriate save set and recovers it. The NetWorker media database and resource database are recovere d when the following message appears:

If your reso urce fi les we re lo st, th ey are now rec overed in the ‘res.R’ directory. Copy or move them to the ‘res’ directory, after you have shut down the service. Then restart the service.

Otherwise, just restart the service. If the on-line index for the server-name was lost, it

can be recovered using the nsrck command.

Task 5: Rename the NetWorker Server Configuration Files

Because the configuration files cannot be reliably overwritten while the NetWorker software is running, mmrecov recovered the res directory as res.R by default. In addition, mmrecov might have recovered another server’s configuration file in this directory.

To rename the configuration files:

1. Stop the daemons by entering the nsr_shutdown command at the

command line:

nsr_shutdown -a

2. Rename the existing /nsr/res directory to /nsr/res.orig:

mv res res.orig

3. Rename the recovered /nsr/res.R directory to /nsr/res:

mv res.R res

4. Restart the NetWorker server by first entering the nsrexecd command, then entering the nsrd command, for example:

nsrexecd nsrd

Legato NetWorker, Release 7.0 Disaster Recovery Guide

Prerequisites

Note: You can also restart the NetWorker server by running the NetWorker startup script for the appropriate platform.

5. After verifying that the NetWorker configurations are correct, remove the /nsr/res.orig directory.

6. Run the nsrjb -HE command to reset the autochanger.

7. If you are using an autochanger, run the nsrjb -Iv command to reinventory the autochanger; or run the nsrjb -Iv -S command to reinventory only the affected slots.

Task 6: Recover All Client File Indexes

Once you recover the server’s media database and resource database, recover all client file indexes on the NetWorker server. You will recover one client file index for each NetWorker client that the NetWorker server backed up.

Note: Because a NetW orker server always has the NetWorker client installed, this task includes recovering the client file index for the NetWorker server.

To recover all client file indexes:

1. Enter the nsrck -L7 command:

nsrck -L7 client_name

2. If you are using a cloned version of th e clie nt f ile index, the NetWorker server may prompt you to load an original volume (not the clone volume).

To use the clone:

a. Enter [Ctrl]+[c] to exit out of nsrck and verify that the pending

original volume message has terminated.

b. Delete the records of the original volumes using the nsrmm -d

volume_name command. For example: The NetWorker server requests the original volume mars.1. Because

this volume is not available, delete the mars.1 volume from the media database using the following command:

nsrmm -d mars.1

c. Enter the nsrck -L7 command:

nsrck -L7 client_name

Note: Although you must recover a computer’s client file index before you can select individual files to recover, you can recover an entire save set on a computer by using a save set recover.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Task 7: Recover the Application and User Data

To recover the application and user data that was on the NetWorker server:

1. Log in as root.

2. Load and inventory the devices. This ensures that the NetWorker server can recognize the location of each volume.

Note: If you load a clone volume, you must either delete the original volume from the media database or mark it as suspect in the media database. If you are using a clone volume, it will be used for the remainder of the recovery process.

3. Run the nwrecover program.

4. Mark all of the directories or files tha t you want to recover.

Important: Do not recover any UNIX operating system boot files that should not be overwritten during a recovery. For more information on boot files, see

“Prerequisites” on page 28.

Chapter 3: UNIX Disaster Recovery

5. Click Start to begin the recovery.

Note: By default, the directed recover option is enabled when you install the NetWorker client. If the directed recover option was disabled on the client before the disaster, you need to explicitly set this option to disable directed recoveries to this client. This option is set through the nsradmin command. For more information about setting the disable directed recover op tion on the NetWorker client, refer to the Legato NetWorker Administrator’s Guide, UNIX Version.

Task 8: Perf orm a Test Bac kup and Recovery

To test the server recovery process:

1. Perform a test backup or recovery to make sure the server is fully recovered.

2. V erify that t he server and its associated clien ts are i ncluded in a sch eduled backup.

Disaster Recovery of Clustered Computers

For disaster recovery of a computer that was running NetWorker software in a cluster environment, see the appropriate chapter for procedures:

• “Chapter 6: Microsoft Cluster Disaster Recovery (Windows NT 4.0)”

• “Chapter 7: Microsoft Cluster Disaster Recovery (Windows 2000 and

.NET)”

Replacing a Hard Drive

Important: To ensure that you have enough disk space to recover all of the failed hard drive’s data, install a new hard drive with at least as much storage capacity as the original drive.

Recovery of the SYSTEM save sets requires extra disk space for temporary files. The recovery operation might require as much extra disk space as the total size of the SYSTEM save sets. For an estimate, run mminfo from the command prompt and check the size of the SYSTEM save sets. In many cases, about 500 MB of temporary disk space is sufficient.

To replace the failed hard drive, the following information is required:

• The storage capacity of the hard drive being replaced, plus the amount of

extra disk space required for temporary files

• The drive letter, size, format, and volume label assigned to each partition

on the hard drive being replaced: Windows .NET, Windows XP Professional, and Windows 2000 — This

information is available in Control Panel > Administrative Tools > Computer Management > Disk Management.

Windows NT 4.0 — This information is available in Start > Programs > Administrative Tools (Common) > Disk Administrator.

Note: Although it will not affect NetWorker operation, you may also want to note any use of mirroring, RAID/striping, compression, or volume se ts.

Install, partition, and format the new hard drive. For instructions, refer to the hard drive manufa cturer’s documentation and the appropriate Microsoft documentation.

• “Task 3: Ve rify the NetWorker Client Recovery” on page 56

OEM Recovery CD Limitations

Many computer manufactures, such as Dell, Hewlett-Packard, Compaq, and IBM, provide a recovery CD or DVD with each system, which typically includes the Windows OS installation files and any additional software that was included with the system. These recovery disks cannot be used to perform an ASR recovery.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

ASR Recovery Requirements

Important: To perform an ASR recovery, you must have an official Microsoft Windows installation CD for the version of Windows you are recovering. If you have only an OEM recovery CD that includes the Windows installation files, skip this section and proceed to “Recovering a Windows Installation” on

page 60. Refer to the OEM documentation as necessary.

ASR Recovery Requirements

To perform an ASR recovery of a NetWorker client host computer, you need:

• The ASR disk for the computer you are recovering. If a current ASR disk

or ASR save set is not available for the failed NetWorker client host computer, you must use the legacy NetWorker disaster recovery method. For a guide to the required procedures, see “Recovering a NetWorker

Client or Storage Node” on page 82.

• The official Microsoft Windows .NET or Windows XP Professional

installation CD for the computer you are recovering

• The latest NetWorker backup for the computer you are recovering Note: To avoid delays during a recovery, if you routinely move NetWorker

backup media to an offsite location for safekeeping, ensure that all necessary volumes are available. To list the media associated with the files you want to recover, run mminfo -mv from the command prompt. For more information about the mminfo command, refer to the Legato Command Reference Guide.

Task 1: Perform an ASR Recovery of the NetWorker Client Computer

To perform an ASR recovery of the NetWorker client computer:

1. On the NetWorker client computer you are recovering, boot from the Windows .NET or Windows XP Professional instal lation CD.

Note: You may need to run the BIOS setup program to configure the computer to boot from the CD-ROM drive. For the procedure, refer to the computer manufacturer ’s documentation.

2. Watch closely at the beginning of the boot process. If prompted, press a key to boot from the CD-ROM drive.

3. During the text-mo de phas e of Windows setup, watch the lower portion of the screen. When prompted, press [F2] to display the ASR Recovery menu. Follow the instructions on the screen.

Chapter 4: Windows Disaster Recovery

4. When prompted, insert the ASR disk into the A: drive and press a key to continue. ASR formats the system partition, copies files, and begins the Windows installation.

Note: Due to a Microsoft Windows XP Professional problem, when you are prompted to insert the ASR disk and press a key to continue, you may need to press a key several times before the system recognizes the disk and proceeds with the recovery. This problem does not occur on Windows .NET systems.

5. If you did not select the Pause During Recovery option while creating the ASR disk, a fully automated recovery will be performed; there will be no pause and you will not be prompted to select which save sets to recover.

If you selected the Pause During Recovery option while creating the ASR disk, during the graphical phase of Windows setup, the NetWorker ASR Client dialog box appears. Expand My Computer and mark the save sets you want to recover, then click Continue. For example, mark the following save sets:

C:\ D:\ SYSTEM STATE:\ SYSTEM DB:\ SYSTEM FILES:\

Note: For more information about the Pause During Recovery option, refer to the Legato NetWorker Administrator’s Guide, Microsoft Windows Version.

Task 2: Restore Components that Require Special Handling

Important: Due to limitations in Microsoft ASR functionality, the following system state components can not be correctly restored during ASR recovery:

– COM+ Registration Database – Disk Quota Database – Windows Management Instrumentation Database

If the NetW orker client being recovered uses any of these components, after an ASR recovery you must perform the following procedure. If the NetWorker client you are recovering does not use any of these components, skip this task and proceed to “Task 3: Verify the NetWorker Client Recovery” on page 56.

Repairing a Win do ws NT 4. 0 Oper ating S ystem In stall ation

This section explains how to use NetWorker software to create a Windows NT

4.0 Emergency Repair Disk (ERD), and how to use the ERD to repair a damaged Windows NT 4.0 operating system installation.

To repair a Windows NT 4.0 operating system installation requires:

• Windows NT 4.0 Setup Disks (three disks)

• Windows NT 4.0 installation CD-ROM (same version that was installed prior to the disaster)

• Windows NT 4.0 Service Pack (same level that was installed prior to the disaster)

• One of the following: – A current Windows NT 4.0 ERD for the computer you are recovering – The NetW o rker backup or clone volume that contains the most recen t

REPAIRDISK save set for the computer you are recovering

• The Administrator account password for the computer you are recovering (required only if you are repairing the registry or system state)

Repairing Windows NT 4.0

If you do not have a current ERD, see “Creating an ERD from the REP AIRDISK

Save Set” on page 57.

If you have a current ERD, see “How to Use the ERD to Repair the Windows

NT 4.0 Installation” on page 59.

Creating an ERD from the REPAIRDISK Save Set

If you do not have a current ERD for the computer you are recovering, you can create one using either the NetWorker User program or the <NetWorker_install_path>\bin\recover.exe command.

Because the operating system of the computer you are recovering needs repair , to create an ERD you must use a different NetWorker client computer to perform a directed recovery of the REPAIRDISK save set. Before you begin the dire cted recovery, ensure that:

• The computer you will use to recover the REPAIRDISK save set is a functional NetWorker for Windows client, connected to the NetWorker server you will use for the recovery.

• The Client resource for the computer you are recovering includes in its Remote Access List the NetWorker server you will use for the recovery.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

Repairing Windows NT 4.0

• The NetWorker server you will use for the recovery includes in its

Administrator list the account you will use to recover the REPAIRDISK save set.

For details about meeting these requirements, refer to the Legato NetWorker Administrator’s Guide, Microsoft Windows Version.

How to Use the NetWorker User Program to Create an ERD

To create an ERD using the NetWorker User program:

1. Start the NetWorker User program.

2. Insert a blank, formatted disk in the A: drive.

3. Click the Recover toolbar button.

4. In the Source Client dialog box, select the computer you are recovering and click OK.

5. In the Destination Client dialog box, select the computer you are using to create the ERD and click OK.

6. Mark the REPAIRDISK save set for recovery.

7. From the Options menu, select Recover Options.

8. In the Relocate Recovered Data To dialog box, enter A:\ and click OK.

9. Click the toolbar Start button to begin recovery of the REPAIRDISK save set to the disk in the A: drive.

Important: If the REPAIRDISK save set is larger than 1.44 MB, it will not fit on a disk. This is a known limitation of the Windows NT 4.0 operating system; no workaround is available.

How to Use the NetWorker recover Command to Create an ERD

Important: The NetWorker recover.exe program is located in

<NetWorker_install_path>\bin. There is also a Windows system command named recover.exe, located in %SystemRoot%\System32. To avoid executing the Windows version of recover .exe when attempting to execute the NetWorker command, you should do one of the following:

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

• Change to <NetWorker_install_path>\bin before executing the recover.exe

command.

• At the command prompt, include the full path and filename to <NetWorker_install_path>\bin\recover.exe.

•Ensure that <NetWorker_install_path>\bin occurs before %SystemRoot%\System32 in your PATH environment variable.

To create an ERD using the NetWorker recover command:

1. On the NetWorker server, insert a blank , forma tted disk into the A: drive.

2. Change to the directory that contains the NetWorker binary files. The default location is <NetWorker_install_path>\bin.

3. Recover the REP AIRDISK save set using the recover command as follows:

recover -c failed_hostname recover> cd / recover> add REPAIRDISK recover> relocate a:\ recover> recover

This procedure initiates recovery of the failed computer’s REPAIRDISK save set to the disk in the NetWorker server’s A: drive.

How to Use the ERD to Repair the Windows NT 4.0 Installatio n

To use the ERD to repair the Windows NT 4.0 installation:

1. On the computer you are recovering, insert Windows NT 4.0 Setup Disk 1 into drive A: and reboot the computer.

2. When prompted, insert Windows NT 4.0 Setup Disk 2 into drive A: and press [Enter].

3. When the Setup Welcome screen appears, press [R] to select the Repair option.

4. Select the appropriate emergency repair options, then select Continue and press [Enter].

5. When prompted, insert Windows NT 4.0 Setup Disk 3 into the A: drive and press [Enter].

4. To complete the recovery process:

• For a NetWorker server, see “Recovering a NetWorker Server” on

page 66.

• For a NetW orker client or storage node, see “Recoverin g a NetWorker

Client or Storage Node” on page 82.

Recovering a NetWorker Server

This section explains how to recover a NetWorker server on a Windows .NET or Windows 2000 host computer.

Important: Before you begin a NetWorker server recovery, you should understand the information about SYSTEM save sets in the Legato NetWorker Administrator’s Guide, Microsoft Windows Version.

Note: For Windows .NET systems, use the following procedure only as a last resort for recovering a NetWorker server. Instead, use the ASR recovery method if possible. For more information, see “Performing Windows ASR

Recovery” on page 53.

NetWorker Server Recovery Requirements

To recover a NetWorker server requires:

• The same release and patch level of the NetWorker software that was in use immediately prior to the disaster

• The installation path of the NetWorker software prior to the disaster

• Backup or clone volumes that contain the NetWorker server’s most recent bootstrap, client file indexes, and filesystem data

Note: To avoid delays during a recovery, if you routinely move NetWorker backup media to an offsite location for safekeeping, ensure that all necessary volumes are available. To list the media associated with the files you want to recover, run mminfo -mv from the command prompt. For more information about the mminfo command, refer to the Legato Command Reference Guide.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

How to Recover a Windows 2000 NetWorker Server

To recover a Windows 2000 NetWorker server, perform the following tasks in the order specified:

• “Task 1: Install the NetWorker Server Software” on page 67

• “Task 2: Configure the NetWorker Server” on page 68

• “Task 3: Locate the NetWorker Server Bootstrap Save Set ID” on page 70

• “Task 4: Recover the NetWorker Server Bootstrap” on page 72

• “Task 5: Rename the Resource Configurati on Files” on page 74

• “Task 6: Reset and Inventory the Autochanger” on page 74

• “Task 7: Recover the NetWorker Server’s Client File Indexes” on page 76

• “Task 8: Recover the NetWorker Server Data” on page 78

• “Task 9: Restore the Removable Storage Jukebox Configuration” on page

• “Task 10: Verify the NetWorker Server Recovery” on page 81

Important: When recovering a NetWorker server that was also being used as a Legato License Manager server (not recommended), the lictype.res file of the Legato License Manager is not restored during the NetWorker server recovery. This is because the Legato License Manager files and directories are not considered part of the NetWorker software. After completing the disaster recovery on the NetWorker server, you must explicitly recover the Legato License Manager as a client of the NetWorker server.

Task 1: Install the NetWorker Server Software

Important: If you updated from NetWorker release 6.x and have not yet performed a scheduled backup of the NetWorker server, reinstall NetWorker release 6.x and use it to recover the bootstrap, then update the NetWorker software and proceed with the recovery.

To install the NetWorker server software:

1. Install to it s original path location the release of the NetWorker server software that was in use prior to the disaster. For instructions, refer to the Legato NetWorker Installation Guide, Microsoft Windows Version.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

NetWorker Server Recovery Requirements

During the installation, keep the foll owing points in mind:

• If the NetWorker installation kit is available on a shared drive, you can install it over the network.

• To update the NetWorker software, first recover the server to its state immediately prior to the disaster, then perform the update.

• You do not need to reload the license enablers; they will be restored later in the recovery process.

• Because the NetW orker mmrecov command is case sensitive, the NetWorker installation path must be in the same case as the ori ginal. For example, C:\Program Files\Legato\nsr is not same as C:\Program Files\legato\NSR.

2. Install any NetWorker patches that were in use prior to the disaster.

Task 2: Configure the NetWorker Server

To configure the NetWorker server:

1. In the NetWorker Administrator program, open the NetWorker server’s Client resource and verify that the Aliases attribute (in the Preferences tab) contains the correct information. For example, aliases for a computer named kingdome might be:

kingdome kingdome.seattle.washington.com

2. Create and configure the NetWorker server’s Device resources. Do not mount or relabel any volumes in the devices. For more information, refer to the Legato NetWorker Installation Guide, Microsoft Windows Version.

• If you are using an autochanger with Removable Storage disabled:

a. Start a Windows command prompt and change to the

<NetWorker_install_path>\bin directory.

b. Create and configure the Autochanger resource using the

jbconfig command. Alternatively, you can use the NetWorker Administrator device autodetection feature.

c. Run the nsrjb -vHE command from the command prompt. This

resets the autochanger, ejects backup volumes, reinitializes the element status, and checks each slot for a volume. If the

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

autochanger does not support the -E option (t o reinitia lize the element status), use the sjiielm command to initialize the element status.

d. If you need to determine which volume contains the bootstrap,

inventory the autochanger by running the nsrjb -Iv command from the command prompt. If y ou know the slot number w he re the bootstrap is located, use the nsrjb -Iv -S # command to inventory that particular slot.

e. If the device the NetWorker server is to use is connected to a

remote storage node, the storage node device needs to be configured. For details, refer to the Legato NetWorker Installation Guide, Microsoft Windows Version.

• If you are using an autochanger with Removable Storage enabled: a. On the desktop, right-click My Computer and select Manage.

b. In the left pane of the Computer Management window, expand

Storage\Removable Storage\Physical Locations.

c. Right click the icon for the autochanger and se lect Inventory.

d. Minimize (but don’t close) the Computer Management window.

e. After the Removable Storage inventory is complete, start the

NetWorker Administrator program and select Devices on the Configure tab.

f. In the Devices window, right-click the Devices icon and select

Create.

g. In the Create Devices dial og box, create a stand-alone NetWorker

Device resource for each drive in the autochanger.

h. In the Computer Management window, double-click the icon for

the autochanger (under Storage\Removable Storage\Physical Locations). Icons for the autochanger’s volumes appear in the right pane.

i. Right-click the icon for the volume that contains the bootstrap

and select Mount.

3. In the NetWorker Administrator program, configure the Client resource for the NetWorker server. Set the browse and retention policies to a time value that covers the oldest save sets being using for th e recovery. This allows you to recover all of the NetWorker server’s records with the mmrecov command.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

NetWorker Server Recovery Requirements

Important: If the browse and retention policies are not long enough to cover all of the save sets you use, all of the NetW orker server’s records are recovered, but any records that are older t h an a mo nt h are discarded because t he defaul t browse policy is one month.

4. If the NetWorker server’s client file index has no t been relocated from its original path, or if you are going to recover a relocated client file index from a backup created with NetWorker release 7.x, skip this step and proceed to “Task 3: Locate th e NetWorker Server Bootstrap Save Set ID”

on page 70.

If you are going to recover the client file index from a backup created with a NetWorker release earlier than 7.x, and you moved the NetWorker server’s client file index path to a different location, you must:

a. Edit the Index Path attribute of the NetWorker server’s Client

resource to reflect the correct path.

b. Stop and restart the following NetWorker services:

– NetWorker Backup and Recover Server – NetWorker Remote Exec Service

Task 3: Locate the NetWorker Server Bootstrap Save Set ID

If you already know the save set ID of the NetWorker server’s most recent bootstrap, skip this task and go to “Task 4: Recover th e NetWorker Server

Bootstrap” on page 72.

The bootstrap contains the NetWorker server’s media database and resource configuration files, which are required for a NetWorker server recovery. For more information about the bootstrap, see “Preparing for Disaster” on page 21.

There are two ways to determine the save set ID of the most recent bootstrap:

1. The faster way to determine the bootstrap save set ID is to find it in the <NetWorker_install_path>\logs\savegrp.log file.

By default, the NetWorker server automatically creates a bootstrap save set after each active scheduled backup that includes the server itself as a client. NetWorker software sends a copy of the bootstrap information to the default printer. You can also configure the NetWorker server to e-mail

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

a copy of the bootstrap information after each scheduled b ackup. The NetWorker server also writes the bootstrap information to the end of the savegrp.log file that is written for the backup.

The following excerpt fr om a savegrp.log file shows a bootstrap save set ID of 1467388673 located on volume lacey.001. Also note the file and record numbers; having this information speeds the recovery process.

Jul 19 17:09:14 la cey: * lacey :bootst rap date time level ssid file record volume 07/19/01 05:08:50 PM full 1467388673 5 0 lacey.001

2. If the bootstrap in formation is not available from the sources described

above, you can locate it by using the NetWorker scanner command, as follows, although this can be time-consuming:

a. Insert the backup or clone volumes from the most recent scheduled

backups into the appropriate device. (Do not use the NetWorker software to mount the media; the NetWorker server does not currently have the necessary information to recognize the media.)

b. Start a Windows command prompt and change to the

<NetWorker_install_path>\bin directory.

c. If you are using an autochanger, load the first volume of the

bootstrap save set into the first drive of the autochanger by running:

nsrjb -lnv -S # -f device_name

where:

– # is the slot where the first volume is located – device_name is the pathname for the first drive

You can obtain the device_nam e by running the NetWorker inquire command.

d. To determine the save set ID of the most recent bootstrap use the

following command:

scanner -B device_name

where device_name is the pathname for the drive where the appropriate volume is loca ted (for example, \\.\T ape0)

Note: If you do not locate the save set ID of the bootstrap from the most recent scheduled backup, run the scanner -B command on the volumes from the next most recent scheduled backup to locate the save set ID of the next most recent bootstrap.

Legato NetWorker, Release 7.0 Disaster Recovery Guide

NetWorker Server Recovery Requirements

Task 4: Recover the NetWorker Server Bootstrap

In this task, you will recover the bootstrap save set. Recovering the bootstrap overwrites the media database in the <NetWorker_install_path>\mm directory and recovers the resource configuration files to a temporary directory named <NetWorker_install_path>\res.R.

Note: The mmrecov command is used to recover only the media database and resource configuration files. To recover the client file indexes (including the NetW orker server’s own client file index) use the nsrck command. For details about the mmrecov and nsrck commands, refer to the Legato Command Reference Guide.

To recover the bootstrap save set:

1. Load the backup or clone volumes that contain the most recent bootstrap save set. If you ran the scanner command in the previous task, you have already completed this step; proceed to step 2.

If you did not run the scanner command in the previous task, do the following:

a. Insert into the storage device the backup or clone volumes that

contain the most recent bootstrap save set. (Do not use the NetWorker software to mount the volume; the NetWorker server does not currently have the necessary information to recognize the media.)

b. If you are using an autochanger, run the following command to load

the first volume of the bootstrap save set into the first drive of the autochanger:

nsrjb -lnv -S # -f device_name

where:

– # is the slot where the first volume is located – device_name is the pathname for the first drive

Note: You can obtain the device_name using the inquire command.

2. To r ecover the NetWorker server’s bootstrap, run the following command:

mmrecov

3. If you are using clone volumes and have not loaded all of the necessary volumes, mmrecov prompts you for the original volume. In that case:

a. Enter [Ctrl]+[c] to exit mmrecov.

b. Delete the records of the original volumes by running the following

command:

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

nsrmm -d volume_name

For example, if the NetWorker software requests the original volume mars.1 but that volume is not available, run the following command to delete mars.1 from the media database:

nsrmm -d mars.1

c. Restart the following NetWorker services:

– NetWorker Backup and Recover Server – NetWorker Remote Exec Service

d. Run the mmrecov command to recover the bootstrap.

4. If the server has multiple devices configured and enabled, the following message appears:

What is the name of the devi ce you pl an on usin g [\\.\Tape1]?

If you receive this message, enter the name of the device you are using for the recovery. For example, enter \\.\Tape0

5. When the following message appears, enter the save set ID for the latest bootstrap. If you are recovering the bootstrap from a clone volume, enter the save set ID associated with the clone.

Enter the latest bootstrap save set ID: 20076

6. When the following message appears, enter the file number to begin the recovery (if k nown) or acce pt the defaul t of zero.

Enter starting file number (if known) [0]: 130

7. When the following message appears, enter the first record number to begin the recovery (if known) or accept the default of zero.

Enter starting record number (if known) [0]: 0

8. When the following message appears, ensure that the volume that contains the correct save set is inserted into the correct backup device, then press [Enter]:

Legato NetWorker, Release 7.0 Disaster Recovery Guide

NetWorker Server Recovery Requirements

The NetWorker software scans the volume for the appropriate save set and then begins the recovery. The NetWorker nsrmmdbasm command is used to recover the media database, and the uasm command is used to recover the resource configuration files. You can use the NetWorker Administrator program to monitor the recovery.

Note: The media database might not be on the same volume as the resource configuration files. If this is the case, the recovery pauses and prompts you when additional media is required.

Task 5: Rename the Resource Configuration Files

Because the NetW orker server’s resource configuration files cannot reliably be overwritten while the NetWorker services are running, the mmrecov command recovers the res directory as res.R.

To put the recovered resource configuration files into effect:

1. Stop the following NetWorker services on the NetWorker server:

• NetWorker Backup and Recover Server

• NetWorker Remote Exec Service

2. Copy the contents of the <NetWorker_install_path>\res.R directory to the <NetWorker_install_path>\res directory.

3. Restart the NetWorker services.

Task 7: Recover the NetWorker Server’s Client File Inde xes

After the NetWorker server’s bootstrap save set is recovered, you can recover the client file indexes in any order; it is not necessary to recover the server’s own client file index before recovering the index of any other client.

Important: If the clients have the NetW orker client software installed, you can run manual and s cheduled backu ps as soon as the Ne tW orker se rver bootst rap is recovered. You can also recover complete save sets. You cannot, however, browse a client’s save sets until you recover the client file index.

Legato NetWorker, Release 7.0

Disaster Recovery Guide

Chapter 4: Windows Disaster Recovery

To recover the client file indexes:

1. To recover the client file indexes, run one of the following commands from the NetWorker server:

•For all clients:

nsrck -L7

•For a specific client:

nsrck -L7 client_nam e

2. If you are recovering the client file indexes from a clone volume, you may be prompted to load the original volume. In that case:

a. Enter [Ctrl]+[c] to exit nsrck.

b. Delete the records of the original volumes by running the following

command:

nsrmm -d volume_name

For example, if the NetWorker software requests the original volume mars.1 but that volume is not available, run the following command to delete mars.1 from the media database:

nsrmm -d mars.1

c. Restart the following NetWorker services:

– NetWorker Backup and Recover Server – NetWorker Remote Exec Service

d. Recover the client file indexes by running one of the following

commands from the command prompt:

•For all clients:

Task 8: Recover the NetWorker Server Data

Important: Recovery of volume mount points and their data requires special handling. It cannot be done using save set recovery. If you attempt to recover a mount point and the mounted volume’s data in a single operation, the dat a will be recovered to the root of the host volume and recovery of the mount point will fail. To successfully recover the mounted volume’s data, you must first manually recreate the mount point, using the same path as the original. You can then perform a separate NetWorker file recovery to restore just the mounted volume’s data (without including any of the host volume’s data in the recovery).

For more information about backing up and recovering mount points, refer to the Legato NetWorker Administrator’s Guide, Microsoft Windows Version. For information about creating mount points, refer to the Windows Online Help topics on creating mounted drives and using the Disk Managemen t utility.

Note: This special handling is no t required when perform ing ASR recovery.

To recover the remainder of the NetWorker server data:

1. Log on to Windows with local administrator privileges.

Note: Directed recovery of SYSTEM save sets is not supported. To recover SYSTEM save sets, you must be logged on to the computer being recovered with local administrator privileges.

2. If you are using an autochanger, make sure it has been inventoried. See

“Task 6: Reset and Inventory the Autochanger” on page 74. This ensures

that the NetWorker server can recognize the location of each volume.

3. If you load a clone volume, the NetWorker software uses the clone volume for the remainder of the recovery pr oces s if either o f the f ollowing is true:

• The original volume was not added back into the media database.

• The original volume was added back into the media database, but it

was not placed in an autochanger and inventoried.

However, if the original volume was added back into the media database, placed in an autochanger, and inventoried, the NetWorker software prompts you to mount the original volume.

Prerequisites

Task 1: Install the NetWorker Software

Task 2: Configure NetWorker Device and Client Resource

To install the NetWorker software:

1. Install the same version of NetWorker software into its original locatio n. For installation instr u c t i ons, refer to the Legato NetWorker Installation Guide, NetWare Version.

• If you want to upgrade the NetWorker server, first recover the server

to its original state, and then perform the upgrade.

• You do not need to reload the license enablers if the NetWorker

configuration files still exist. By defa ult, the configuration files are located in the SYS:NSR\RES directory.

2. Install any NetWorker patches that were installed prior to the disaster.

To configure the device and client resource:

1. Configure the Device resource:

Note: If you are recovering data using an autochanger, enter [F4] to verify that the autochanger correctly appears in the Autochanger window.

2. Configure the Client resource associated with the server. Set the browse and retention policies to a decade. The browse policy is one

quarter (four months) by default. This enables you to recover all of the server’s records.

Important: If you do not reset the browse and retention policies, all of the server’s records will be recovered. However, any records that are more than one quarter (four months) old will be discarded, because the browse policy is one quarter by default.

Task 3: Locate the Server’s Bootstrap Save Set ID

This section describes how to locate the save set ID for the NetWorker server’s latest bootstrap. The NetWo rker server’s bootstrap contains the server’s online file index, media index, and resource configuration files.

Use the following steps to locate the save set ID of the most recent bootstrap if you do not have this information:

1. Insert the most recent media or clone volumes used for scheduled backups into the appropriate device.

2. At the NetWare system console, switch to the directory where the NetWorker NLMs are located. By default, these files are located in the SYS:NSR\BIN directory.

3. Use the scanner -B command to locate the most recent bootstrap on the media.

Task 4: Recover the NetWorker Server Bootstrap

This section describes how to recover the NetWorker server’s bootstrap. By default, these files reside in the SYS:NSR and SYS:NSR\RES directories, and can be recovered using the NetWorker Utilities program.

To recover the NetWorker bootstrap:

1. Load and inventory the devices. This e nsures that the NetW o rker softwar e can recognize which slots contain which volumes.

If you load a clone volume into a device, the NetW orker software will use the clone volume for the remainder of the recovery process. You might have to update the volume location to indicate that the original volume is not available.

2. Start the NetWorker Utilities program by entering the following command at the NetWare system console:

load NETUTIL

Important: Disable scheduled backups and do not use th e NetW orker software to perform backups or recoveries while running the NetWorker Utilities program. If backup and recovery processes are enabled, the state of the NetWorker indexes will become confused. From the NetWorker Utilities dialog box, select Recover from a Disaster.

3. Enter the full name of the backu p adm inistrator (for example, “.cn=Admin.O= ‘top level container’”) into the User text box and the appropriate NetWare password into the Password text box and press [Enter].

The Device Selection window appears.

4. From the Device Selection window , select the device you intend to use and press [Enter].

5. Insert the most recent media or clone volumes used for scheduled backups into the appropriate device.

• If you are using a single tape device, manually insert the volume.

• If you are using an autochanger, use the autochanger controls to

manually select the slot containing the most recent backup volume.

To determine the required backup volume, refer to the printed bootstrap records.

6. Press [Enter] when the following message appears.

Put the volume for disaster recovery in device xxxx and press Enter.

7. Press [Enter] to exit the NetWorker Utilities. The server’s processor will halt with multiple ABENDs.

8. Restart the NetWorker software.

9. From the NetWorker Utilities program, select F3>Operation>Recover.

Task 7: Restore NDS Data

7. From the [F2] File menu, select Start Recover, and press [Enter].

8. If you have NDS data to restore, continue with “T as k 7: Resto re NDS Da ta”

on page 100.

If you do not have any NDS data to restore, continue with “Task 8:

Complete the Server Recovery” on page 101.

Before performing an NDS backup or recover, refer to the Novell Application Notes section “Backing Up and Restoring Novell Directory Services in NetWare 4.11,” dated October 1996. This document explains concepts and procedures that you need to understand before working with NDS backups and recovers .

On networks with multiple servers, NDS automatically creates replicas (copies) of the NDS database or portions of it (partitions) and stores them on other servers. This process provides a readily available backup if NDS or a partition is damaged. Do not circumvent this replication process.

Whenever possible, use an active replica to restore what was lost from the NDS tree. If this is not feasible, you must restore from a Storage Management Services (SMS) backup in the following way:

100

1. Restore the NDS information.

2. Restore the filesystem data and trustee rights. NDS backup and restore is based on object names. The objects must exist

in the tree before you can restore the filesystem data and trustee assignments for those objects. NDS should be f unctional (time and partitions synchronizing normally) before you proceed with a restoration.

To restore NDS data to this server using the NetWorker software:

a. From the [F3] Operation menu, select Save Set Recover, and press

[Enter].

b. Select this server’s name as both the source and destination client.

c. Enter the full name of the backup administrator, and the password.

d. Select the {NDS} save set, and press [Enter] to d isplay versions.

e. Select the version with the most recent full backup.

If there are any later save sets with level 1 or incremental backups, recover them from the oldest to the most recent.

The NDS is now restored to the state of the most recent backup.
