NetBackup and Backup Exec OST Guide Introduction I This guide is for ETERNUS CS800 S6 3.2 Software. Symantec OST (Open Storage) allows NetBackup and Backup Exec to seamlessly integrate with an ETERNUS CS800 S6 disk backup system. Once installed and configured, NetBackup or Backup Exec can manage the backups through the ETERNUS CS800 S6 and take advantage of the system s capabilities such as data deduplication and replication. Installing and configuring the ETERNUS CS800 S6 and OST for operation consists of the following major steps. See the following sections for detailed instructions for completing each step: 1. Installing the OST Plug-in 2. Configuring the ETERNUS CS800 S6 3. Configuring Symantec NetBackup (Media Server) 4. Configuring Symantec Backup Exec (Media Server) 5. Initiating an OST Backup 6. Performing OST Optimized Duplication 7. Configuring OST Path to Tape (NetBackup only) 8. Configuring ETERNUS CS800 S6 Accent V CAUTION! You must upgrade to Backup Exec 2010 R3 or later before configuring Backup Exec. R3 is a maintenance release that provides OST fixes that are required by ETERNUS CS800 S6 software version 2.x. Installing the OST Plug-in Before you can configure the ETERNUS CS800 S6 with OST, download the OST Plug-in and install it on a media server. The following versions of Symantec NetBackup are supported: For Replication (Optimized Duplication) - NetBackup 7.1.x or later. U41853-J-Z125-5-76 9

Installing the OST Plug-in NetBackup and Backup Exec OST Guide For OST Path To Tape (Direct To Tape) - NetBackup 7.1.x or later. For OST AIR (Automatic Image Replication) - NetBackup 7.1.x or later For OST Optimized Synthetics - NetBackup 7.1.x or later. The following version of Symantec Backup Exec are supported: Backup Exec 2012 The OST Client Plug-in is provided as follows: On a data medium shipped together with the ETERNUS CS800 S6 system. A README file is included which contains detailed instructions about the installation. At the Fujitsu support pages under: http://support.ts.fujitsu.com/com/support/index.html To download the OST Plug-in from the support pages: 1. On the system remote management console, navigate to the Configuration > OST > OST Client Plug-In page. 2. Click Client Plug-In Download. 3. Select Drivers & Downloads. In the next window fill in the following values in the section Product selection (manually search). 1. Storage 2. ETERNUS CS/CentricStor 3. ETERNUS CS800 <version> You will get a list of supported operating systems. Select the desired one. Under Software you will find the available OST Plug-ins. Make sure to download the correct OST Plug-in for the operating system installed on the NetBackup media server. In the OST Plug-in zip-file you will find a README file, which contains the installation procedure for the OST Plug-in. This procedure is different for each media server operating system platform. Follow the instructions to install the OST Plug-in on the media server. When you are finished, continue to the next section. I When multiple hosts are using a single system, you can distribute the load by dividing the hosts into groups. For more information, see the section Performance Tuning in the README file. I The OST Plug-in for Windows is installed in the NetBackup or Backup Exec installation directory. 10 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Configuring the ETERNUS CS800 S6 I RAWS is an agent used to backup Windows clients (which Backup Exec calls remote agents). In Backup Exec, a remote agent (client) has the ability to perform a client side deduplication which is called Direct Access. This requires the OST plug-in to be installed on the remote agent and the plug-in.dll to exist in the \Backup Exec\RAWS directory. Configuring the ETERNUS CS800 S6 You must configure storage servers and logical storage units on the ETERNUS CS800 S6 remote management console before you configure NetBackup or Backup Exec. See the following sections to configure the ETERNUS CS800 S6 for OST. Configuring the ETERNUS CS800 S6 consists of the following major steps. See the following subsections for detailed instructions for completing each step: Configuring OST Authentication Configuring Storage Servers Configuring Logical Storage Units Target IP Mapping I You can also use the OST Wizard to configure the ETERNUS CS800 S6 for OST. Configuring OST Authentication To authenticate the OST storage servers on a media server, you must create OST user credentials. V If you have upgraded to 2.x Software from a version released prior to 2.0, you must add new OST credentials to the ETERNUS CS800 to continue using OST. Shut down the NetBackup or Backup Exec services. Then perform the procedure below, making sure to use the same username and password that were used to register the existing OST devices. Finally, start the NetBackup or Backup Exec services. To create OST user credentials: 1. Log on to the ETERNUS CS800 S6 remote management console. 2. Navigate to the Configuration > OST > Manage Users page (see Figure 1). U41853-J-Z125-5-76 11

Configuring the ETERNUS CS800 S6 NetBackup and Backup Exec OST Guide Figure 1: Manage Users Page 3. Click Add. 4. Specify the Username and New Password that will be used to authenticate the storage servers on the media server. I For username, alphanumeric characters are allowed, as well as underscores ( _ ) and hyphens ( - ). For password, alphanumeric characters are allowed, as well as the following special: ` ~! @ # $ % ^ & * ( ) - _ = + [ { ] } \ ; : ', <. > /? 5. Click Apply. V In NetBackup or Backup Exec, add credentials for the storage server, making sure to use the same OST username and password you entered on the ETERNUS CS800 S6. For more information, see "Registering the Storage Server with NetBackup and Discovering Logical Storage Units" on page 28 or "Configuring Backup Exec and Logical Storage Units" on page 51). 12 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Configuring the ETERNUS CS800 S6 Configuring Storage Servers To configure storage servers: 1. Log on to the ETERNUS CS800 S6 remote management console. 2. Navigate to the Configuration > OST > Storage Servers page (see Figure 2). Figure 2: Storage Servers Page Use the Storage Server page to perform the following tasks. See the following subsections for detailed instructions for completing each task: "Adding a Storage Server" "Editing a Storage Server" "Deleting a Storage Server" I It is recommended to create a different storage server for each NetBackup or Backup Exec domain (master server plus associated media servers). This segregates data so a NetBackup or Backup Exec administrator cannot accidentally modify or remove backup images belonging to another domain. U41853-J-Z125-5-76 13

Configuring the ETERNUS CS800 S6 NetBackup and Backup Exec OST Guide Adding a Storage Server To add a storage server: I You can create up to 100 storage servers. 1. On the Storage Servers page, click Add. The Add Storage Server page displays (see Figure 3). Figure 3: Add Storage Server Page 14 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Configuring the ETERNUS CS800 S6 2. Under Add Storage Server, enter information about the storage server: Name - Enter the name of the storage server. V CAUTION! Do not use an underscore ( _ ) in the name of the storage server. I Storage server names must be unique and not used again on other ETERNUS CS800 S6 systems. Also, storage server names are case sensitive on all platforms including Windows. Description - (Optional) Enter a brief description of the storage server. Max Connections - Enter the maximum number of connections allowed to the storage server (3 to 65536). The maximum connections indicate the number of NetBackup or Backup Exec jobs that can connect to the storage server. I It is recommended to set this value to 300 so that media servers never run out of storage server connections. Enable Concurrent Optimized Duplication - Select the check box to enable optimized duplication during OST ingest. Concurrent Optimized Duplication is disabled by default. If enabled, as data is written to the storage server, it is simultaneously replicated to the target ETERNUS CS800 S6. When optimized duplication or Automatic Image Replication subsequently occurs, the operation is more efficient because a portion of the required data has already been replicated to the target storage server. I To use Concurrent Optimized Duplication, you must configure the source ETERNUS CS800 S6 and target ETERNUS CS800 S6 for replication (see "Replication Channel for OST (NetBackup Only)" on page 63). I When Concurrent Optimized Duplication is enabled, all data on the storage server is duplicated, not just the specified images. 3. Select the check box for each optimized duplication target you want to duplicate the storage server to. When the storage server is duplicated, its data will be sent to all selected targets. 4. Under Logical Storage Unit, enter information about the LSU to add to the new storage server: Available Capacity - (Recommended for best performance) Select this option to add an LSU that uses the available capacity on the system. You cannot add an available capacity LSU to a storage server that already contains an LSU. Also, if you add an available capacity LSU to a storage server, you cannot add additional LSUs to that same storage server. U41853-J-Z125-5-76 15

Configuring the ETERNUS CS800 S6 NetBackup and Backup Exec OST Guide I After you add an LSU that uses the Available Capacity option, you cannot change the LSU to use the Specific Capacity option. Instead, you must delete the LSU, then add a new LSU and choose the Specific Capacity option (see "Deleting an LSU" on page 23). Specific Capacity - Select this option to specify the physical capacity of the LSU, and then enter the following information. LSU Name - Enter the name of the LSU. Physical Capacity - Enter the physical capacity of the LSU (1 to 1048576 GB). I It is recommended to set LSUs to maximum size (1048576 GB, because spanning them on a backup is not possible). 5. (Optional) In the Description box, enter a brief description of the LSU. 6. (Optional) Select the Enable Automatic Image Replication check box to automatically replicate (duplicate) data on the LSU to a remote LSU on another ETERNUS CS800 S6. Automatic Image Replication (AIR) is disabled by default. If enabled, data on an LSU is automatically replicated to a remote LSU that resides on an ETERNUS CS800 S6 in a different NetBackup domain. The timing of the duplication, as well as the backup images that are duplicated, are determined by the storage lifecycle policies (SLPs) configured in NetBackup. OST AIR requires NetBackup 7.1.x or higher. For more information, see "Setting Up Automatic Image Replication" on page 65. I To use Automatic Image Replication, you must configure the source ETERNUS CS800 S6 and target ETERNUS CS800 S6 for replication (see "Replication Channel for OST (NetBackup Only)" on page 63). I You must configure at least one remote user before you can enable Automatic Image Replication (see "Create a Remote User for OST AIR" on page 67). 7. If Automatic Image Replication is enabled, select the replication target you want to replicate images to. (You can select only a single target.) When images are replicated, data will be sent to the selected target. 8. If Automatic Image Replication is enabled, specify the following information: Remote Storage Server Name - The name of the remote storage server (on the target ETERNUS CS800 S6) to replicate data to. The source ETERNUS CS800 S6 and target ETERNUS CS800 S6 must reside in different NetBackup domains. I To configure the target ETERNUS CS800 S6, see "Replication Channel for OST (NetBackup Only)" on page 63. 16 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Configuring the ETERNUS CS800 S6 Remote LSU Name - The name of the LSU in the remote storage server that will receive the replicated data. Remote User - The OST user credentials to use for authentication on the remote (target) ETERNUS CS800 S6. The selected remote user must match a local user on the Configuration > OST > Manage Users page on the target ETERNUS CS800 S6 (see "Configuring OST Authentication" on page 11). 9. Click Apply. Editing a Storage Server To edit a storage server: 1. On the Storage Servers page, select the storage server and click Edit. 2. Enter information about the storage server: I If you are editing a storage server, the Name option cannot be changed. Description - (Optional) Enter a brief description of the storage server. Max Connections - Enter the maximum number of connections allowed to the storage server (3 to 65536). The maximum connections indicate the number of NetBackup or Backup Exec jobs that can connect to the storage server. The maximum number of connections cannot be changed if the storage server has more than zero currently active connections. The number of active connections is displayed on the OST page (see Figure 2). I It is recommended that this value is set to 300 so that media servers never run out of storage server connections. Enable Concurrent Optimized Duplication - Select the check box to enable optimized duplication during OST ingest. Concurrent Optimized Duplication is disabled by default. If enabled, as data is written to the storage server, it is simultaneously replicated to the target ETERNUS CS800 S6. When optimized duplication or Automatic Image Replication subsequently occurs, the operation is more efficient because a portion of the required data has already been replicated to the target storage server.

Configuring the ETERNUS CS800 S6 NetBackup and Backup Exec OST Guide Target IP Mapping The Target IP Mapping page allows you to associate a data IP address with a replication IP address on a target ETERNUS CS800 S6. This can be necessary if the target ETERNUS CS800 S6 is configured with different network interfaces (and therefore different IP addresses) for data and replication traffic. Generally, OST traffic is routed to the data network segment. However, the OST Automatic Image Replication (AIR) and Concurrent Optimized Duplication features use the replication network segment to transmit data to the target system. (Optimized duplication can optionally use the replication channel.) When a data IP address is mapped to a replication IP address, OST traffic that is sent to one of the IP addresses is routed to the other IP address as necessary. I You must add target IP mapping information if you are performing optimized duplication on a segmented network and replication is not configured between the source ETERNUS CS800 S6 and target ETERNUS CS800 S6. I Fujitsu Technology Solutions does not recommend mapping multiple data IP addresses to a single replication IP address. If you have mapped multiple data IP addresses and the routing is not working, try removing the additional data IP addresses, and map only a single data IP address. To access the Target IP Mapping page, on the OST page, click the Target IP Mapping tab (see Figure 6). 24 U41853-J-Z125-5-76

Configuring Symantec NetBackup (Media Server) See the NetBackup System Administrator s Guide for information about NetBackup installation and basic configuration. Also, see the NetBackup Shared Storage Guide before proceeding further. V CAUTION! You MUST have all NetBackup 7.1.x updates applied (including the Java client and any for OST path-to-tape) before continuing with configuration. To configure Symantec NetBackup for OST, see the following sections: "Registering the Storage Server with NetBackup and Discovering Logical Storage Units" "Configuring Disk Pools and Storage Units in NetBackup" U41853-J-Z125-5-76 27

Configuring Symantec NetBackup (Media Server) NetBackup and Backup Exec OST Guide Registering the Storage Server with NetBackup and Discovering Logical Storage Units After the OST Plug-in is installed and configured on the NetBackup media server, you must register the storage servers with NetBackup by defining them on the media server. You must complete this process on every media server that will access the storage servers on the ETERNUS CS800 S6. You can configure multiple media servers to use the same storage servers as long as the OST Plug-in is installed on each media server. To register a storage server, first define it using the nbdevconfig command, and then provide credentials using the tpconfig command. I You can perform this process using the Storage Server Configuration Wizard instead of the CLI commands (see "Using the Storage Server Configuration Wizard" on page 32). Perform the procedure for the operating system on the media server: "Registering the Storage Server on Windows Platforms" on page 28 "Registering the Storage Server on Unix/Linux Platforms" on page 30 I The storage server argument passed to the nbdevconfig command should be in the form of <name_ip>, where the name is the name of storage server to be registered and IP is the IP address of the ETERNUS CS800 S6. If the ETERNUS CS800 S6 is configured with multiple network interfaces (see the User s Guide for ETERNUS CS800 S6 system) the IP will be the network interface used for data. This is also applicable when registering storage servers on a Windows platform. I If the IP address of the ETERNUS CS800 S6 or media server changes at any time after registering the storage servers (for example, due to switch changes), you must delete the existing storage servers and disk pools on the media server, and then register the storage servers again using the procedures below. You must take these actions on all media servers that access the storage servers. Registering the Storage Server on Windows Platforms I The procedures in this section assume NetBackup is installed in the default location. If you installed Netbackup in a different drive or location, modify the commands with the correct path. I For complete usage information about these commands, refer to NetBackup Commands for Windows. To register the storage server on a Windows NetBackup media server platform, perform the following steps: 28 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Initiating an OST Backup Performing Synthetic Full Backups (NetBackup Only) A synthetic backup is a backup in which content from a series of backups, starting with a full backup and followed by incremental backups, is combined into a new backup-typically a full backup. For a synthetic backup to be successful, all the backups from the series must be intact and internally consistent. Intact means that each backup created still exists and no backup in the series has been expired. Internally consistent means that the individual backup catalogs are all consistent. The catalogs can become inconsistent for a variety of reasons, for example, by running two backups for a client and policy concurrently. (A scenario when this example can occur is if a manual incremental backup is performed while a scheduled incremental backup job is in progress.) During a synthetic backup, the backup application first queries and analyzes the backups for the given policy and client and then attempts to use their catalog data to combine the content into a new logical backup. If a backup is missing, or if file metadata is inconsistent, the synthetic backup will fail with an error 671. Inconsistent incremental metadata due to, prior to NetBackup 7.1, use of dynamic selections and multistreaming. Primary causes of error 671 include the following: Expiration of a backup in the full/incremental series. Inconsistent incremental metadata due to concurrent backups in the series. Inconsistent incremental metadata due to utilization of Windows Archive Bit and cumulative incremental backups. To configure NetBackup to store optimized synthetic full backups verify the OptimizedImage flag is set for the storage server and the disk pool. To confirm the OptimizedImage flag is set use /usr/openv/netbackup/bin/admincmd/nbdevquery -liststs -U for the storage server and /usr/openv/netbackup/bin/admincmd/nbdevquery -listdp -U for the disk pool. To add the OptimizedImage flag to a existing server use /usr/openv/netbackup/bin/admincmd/nbdevconfig -changests -stype FTS -storage_server <storage-server-name> -setattribute OptimizedImage and to the disk pool use /usr/openv/netbackup/bin/admincmd/nbdevconfig -changedp -stype FTS -dp <disk-poolname> -setattribute OptimizedImage. To configure NetBackup optimized synthetic full backups also see Symantec Technical Solution note TECH77767. U41853-J-Z125-5-76 59

Performing OST Optimized Duplication NetBackup and Backup Exec OST Guide Performing OST Optimized Duplication The ETERNUS CS800 S6 has the capability to copy data on one system to another system (that is, the capability to perform replication). NetBackup or Backup Exec uses this capability to initiate an optimized duplication of backup images between these appliances. The duplication operation of NetBackup or Backup Exec triggers the duplication function in the OST disk appliance if both the source and destination volumes for the copy are OST LSUs. OST optimized duplication reduces the workload on the NetBackup or Backup Exec media server because the replication is performed by the ETERNUS CS800 S6. Duplication is done in the background, and it is faster because it uses data deduplication capabilities to reduce the copy bandwidth. Duplication is still initiated, managed, and controlled by the NetBackup or Backup Exec media server while the actual data movement process is offloaded to gain the maximum benefits from the Fujitsu appliance s replication capabilities. The ETERNUS CS800 S6 can replicate (duplicate) OST data to another ETERNUS CS800 S6 using the following methods: Optimized Duplication - With optimized duplication, backup images on a storage server can be replicated to another storage server on an ETERNUS CS800 S6 that resides in the same NetBackup or Backup Exec domain. The duplication occurs when it is initiated in NetBackup (see "Initiating an OST Optimized Duplication" on page 61). Automatic Image Replication (AIR) - If you are using Symantec NetBackup 7.1 or higher, you can configure an LSU for Automatic Image Replication (see "Setting Up Automatic Image Replication" on page 65). If enabled, data on an LSU is automatically replicated to a remote LSU that resides on an ETERNUS CS800 S6 in a different NetBackup domain. The timing of the duplication, as well as the backup images that are duplicated, are determined by the storage lifecycle policies (SLPs) configured in NetBackup. Concurrent Optimized Duplication - For both optimized duplication and Automatic Image Replication, you can optionally enable Concurrent Optimized Duplication (see "Configuring Storage Servers" on page 13). If enabled, as data is written to the storage server, it is simultaneously replicated to the target ETERNUS CS800 S6. When optimized duplication or Automatic Image Replication subsequently occurs, the operation is more efficient because a portion of the required data has already been replicated to the target storage server. It is important to remember that, with Automatic Image Replication, the local and remote LSUs reside in different NetBackup domains. This differs from optimized duplication, which occurs between two LSUs residing within the same NetBackup domain. I For information about configuring NetBackup for optimized duplication or Automatic Image Replication (also referred to as duplicating images to a remote master server domain), see the Symantec NetBackup Administrator's Guide. 60 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Performing OST Optimized Duplication Initiating an OST Optimized Duplication I To increase the performance, Fujitsu Technology Solutions recommends configuring the ETERNUS CS800 S6 to use the replication channel when performing optimized duplication (NetBackup only) (see "Replication Channel for OST (NetBackup Only)" on page 63). I For Backup Exec, no more than two concurrent optimized duplication streams per source ETERNUS CS800 S6 to a target ETERNUS CS800 S6 are supported. Additional concurrent streams are not optimized. To initiate an optimized duplication, refer to the following sections: "Initiating Optimized Duplication in NetBackup" "Initiating Optimized Duplication in Backup Exec" Initiating Optimized Duplication in NetBackup To initiate an optimized duplication with the Administration Console: In the NetBackup Administration Console, expand the NetBackup Management Catalog.

For more information, see Duplicating Backup Images in the Backup Exec Administrator's Guide. Replication Channel for OST (NetBackup Only) Replication Channel for OST leverages the replication capabilities of the ETERNUS CS800 S6 (normally used to replicate NAS shares and VTL partitions) to perform optimized duplication using NetBackup. This significantly increase optimized duplication performance. In addition, more than two optimized duplication streams per source ETERNUS CS800 S6 are supported. Replication Channel for OST is automatically used when the IP address of the target NetBackup storage server matches the IP address of the configured target ETERNUS CS800 S6. You can configure up to two replication targets. In segmented network configurations, when Replication Channel for OST is enabled, optimized duplication uses the replication interface instead of the data interface. Also, the IP address of the target NetBackup storage server (which acts as a data channel IP of the target) can be mapped to the replication IP (see "Target IP Mapping" on page 24). I Replication Channel for OST is compatible with NetBackup only. Using the replication channel to perform optimized duplication with Backup Exec is not supported. To use Replication Channel for OST when performing optimized duplication: 1. Log on to the ETERNUS CS800 S6 remote management console. 2. On the target ETERNUS CS800 S6, perform the following steps: a) Navigate to the Configuration > Replication page (see Figure 32). U41853-J-Z125-5-76 63

Performing OST Optimized Duplication NetBackup and Backup Exec OST Guide Figure 32: Replication Receive Page b) Under Source systems, click Add. c) In the Source Hostname or IP box, enter the host name or IP address of the system that will send the replicated data. d) Click Apply. 3. On the source ETERNUS CS800 S6, perform the following steps: a) Navigate to the Configuration > Replication page (see Figure 32). b) Under Target systems, click Add. c) In the Target Hostname or IP box, enter the hostname or IP address of the system that will receive the replicated data. d) In the Encryption drop-down box, select the type of encryption to use when sending replication data to the target system (None, 128-bit, or 256-bit). Using 256-bit encryption (default) provides a stronger level of security but may have an impact on system performance in some situations. For best performance, if your data network is already secured, you should select None for encryption. V CAUTION! For encryption, select None or 128-bit if you are sending data to a ETERNUS CS800 S6 running a system software version prior to ETERNUS CS800 S6 2.1 Software. e) In the Source IP box, enter the IP address that is used to uniquely identify the source ETERNUS CS800 S6 to the target. This may be different than the actual network IP address of the source ETERNUS CS800 S6. If the target system is at ETERNUS CS800 S6 2.1 Software or higher, the Source IP field is not required. If the target system is at ETERNUS CS800 S6 2.0.1.x Software or below, then you must enter the IP address by which the target system recognizes the source system. The default value is 0.0.0.0. 64 U41853-J-Z125-5-76

NetBackup and Backup Exec OST Guide Setting Up Automatic Image Replication I The Source IP field does not accept fully qualified domain names. You must enter a valid IP address. Make sure this IP address is configured in the allowable sources list on the target ETERNUS CS800. f) Click Apply. 4. Perform optimized duplication as normal. Setting Up Automatic Image Replication OST AIR requires NetBackup 7.1.x or higher. Setting up Automatic Image Replication (AIR) requires that you first configure the target (remote) ETERNUS CS800 S6 and then the source ETERNUS CS800 S6 (see Figure 33). In addition, you must create storage lifecycle policies (SLPs) in NetBackup that define when the automatic replication occurs and which backup images are duplicated. To automatically replicate (duplicate) all data on an LSU to a remote LSU that resides on an ETERNUS CS800 S6 in a different NetBackup domain: 1. On the target system, add the source system to the list of allowed replication sources (see "Replication Channel for OST (NetBackup Only)" on page 63). 2. On the target system, create a local OST user (see "Configuring OST Authentication" on page 11). V CAUTION! On the target system, make sure to create a local user on the Configuration > OST > Manage Users page. 3. On the target system, create a storage server and LSU to receive the replicated OST data (see "Configuring Storage Servers" on page 13). I Fujitsu Technology Solutions recommends selecting the Available Capacity option when creating an LSU for use with Automatic Image Replication. 4. On the source system, configure replication to the target system (see "Replication Channel for OST (NetBackup Only)" on page 63). 5. On the source system, create a remote OST user with the same user name and password that you used in step 2 above (see "Create a Remote User for OST AIR" on page 67). V CAUTION! On the source system, make sure to create a remote user on the Configuration > OST > Manage Users page. U41853-J-Z125-5-76 65

Setting Up Automatic Image Replication NetBackup and Backup Exec OST Guide 6. On the source system, create a storage server and LSU, and enable the LSU for Automatic Image Replication (see "Configuring Storage Servers" on page 13). For Remote Storage Server and Remote LSU, make sure to specify the storage server and LSU created in step 3 above. Also, for Remote User, make sure to select the remote user created in step 5 above. 7. Register and configure the storage servers in NetBackup (see "Registering the Storage Server with NetBackup and Discovering Logical Storage Units" on page 28). Also, create disk pools in NetBackup and make sure the Replication property on the disk pool is updated (see "Configuring Disk Pools and Storage Units in NetBackup" on page 38). If the disk pool is the source, the Replication property of the disk pool should be source. If the disk pool is the target on the remote NetBackup media server, then the Replication property should be target. I A disk pool can be a target and also a source to another remote NetBackup media server. Make sure that the Replication property on the disk pool is updated before creating the storage lifecyle policies (SLPs). 8. Configure storage lifecycle policies in NetBackup to control when automatic replication of the LSU occurs (see the Symantec NetBackup Administrator's Guide).

NetBackup and Backup Exec OST Guide Configuring OST Path to Tape (NetBackup only) Configuring OST Path to Tape (NetBackup only) The OST path to tape (Direct to Tape) option allows you to copy OST LSUs to a physical tape library. I This procedure assumes that you have physically connected the ETERNUS CS800 S6 and the target library using Fibre Channel either directly or through a Fibre Channel SAN. If you are connecting the devices using a SAN, you must perform the appropriate Fibre Channel switch zoning. You must also appropriately map the library device LUNs on the library side to correctly present them to the ETERNUS CS800 S6. Configuring OST path to tape consists of the following major steps. See the following subsections for detailed instructions for completing each step: Verifying Prerequisites Configuring Physical Tape Libraries Configuring NetBackup OST for Path to Tape Verifying Prerequisites The following steps must be completed before setting up NetBackup OST path to tape: The NetBackup version running on the media server must be 7.1.x, with all updates applied. The ETERNUS CS800 S6 must be installed and configured. Fibre Channel connectivity must be configured. Aliases for the NDMP host (the ETERNUS CS800 S6) must be created on the EMM server (see "Creating Aliases for the NDMP Host"). Creating Aliases for the NDMP Host For optimal path to tape (direct copy) performance, you should create aliases for the NDMP host (the ETERNUS CS800 S6) on the Enterprise Media Manager (EMM) server. If you create aliases for the ETERNUS CS800 S6, then data is sent directly from the ETERNUS CS800 S6 to tape during path to tape (direct copy) operations. If you do not create these aliases, data will be sent from the ETERNUS CS800 S6 to the media server, then back to the ETERNUS CS800 S6 before it is written to tape, which can cause slower performance. U41853-J-Z125-5-76 69

Configuring OST Path to Tape (NetBackup only) NetBackup and Backup Exec OST Guide To create aliases for the NDMP host: 1. On the EMM server, retrieve a list of all NDMP hosts (ETERNUS CS800 S6 systems). For Windows, run the following command: C:\Program Files\Veritas\NetBackup\bin\admincmd\nbemmcmd -listhosts -machinetype ndmp For Linux or Solaris, run the following command as root: /usr/openv/netbackup/bin/admincmd/nbemmcmd -listhosts -machinetype ndmp 2. For each host (ETERNUS CS800 S6) returned in Step 1 that will be performing direct copy to tape, retrieve a list of aliases For Windows, run the following command: C:\Program Files\Veritas\NetBackup\bin\admincmd\nbemmcmd -machinealias -getaliases -machinename <ndmphost> -machinetype ndmp For Linux or Solaris, run the following command as root: /usr/openv/netbackup/bin/admincmd/nbemmcmd -machinealias -getaliases -machinename <ndmphost> -machinetype ndmp 3. A host (ETERNUS CS800 S6) should have all available aliases: NetBIOS hostname, DNS hostname, and FQDN (fully qualified domain name). If the host (ETERNUS CS800 S6) does not have one or more of these aliases, you should create them. To create an alias for a host (ETERNUS CS800 S6), use the following commands. For Windows, run the following command: C:\Program Files\Veritas\NetBackup\bin\nbemmcmd.exe -machinealias -machinename <ndmphost> -addalias -alias hostname.domain.gov -machinetype ndmp For Linux or Solaris, run the following command as root: /usr/openv/netbackup/bin/admincmd/nbemmcmd -machinealias -machinename <ndmphost> -addalias -alias hostname.domain.gov -machinetype ndmp I To correct any DNS issues (or simply to be proactive), you can add the entries to the hosts file. 70 U41853-J-Z125-5-76

Configuring OST Path to Tape (NetBackup only) NetBackup and Backup Exec OST Guide Running a Duplication to Tape NetBackup uses NDMP direct copy when you duplicate a backup image. Certain conditions apply to the duplication, explained in this section. To run a duplication, you can use any of the following methods: The Duplicate option in the Catalog node of the NetBackup Administration Console. NetBackup (see the NetBackup Administrator s Guide). The bpduplicate command (see the NetBackup Commands Guide). A NetBackup Storage Life-cycle Policy. Requirements For NetBackup to use NDMP direct copy when you duplicate an image: As the destination for the duplication, you must designate an NDMP storage unit in an ETERNUS CS800 S6. An NDMP tape drive must be available to mount the target image. The NDMP tape drive must be a physical tape drive in a tape library. If these two requirements are met, NDMP direct copy is enabled. NetBackup copies the image directly to the designated storage unit without using media server I/O or network bandwidth. Initiate NDMP Direct to Tape with the Administration Console To initiate an NDMP Direct to Tape with the Administration Console: 1. In the NetBackup Administration Console, expand NetBackup Management > Catalog. 2. Set up the search criteria for the image you want to duplicate. Click Search Now. 3.
