The IBM Storwize V7000 Unified system includes the IBM Storwize V7000 file module and the Storwize V7000 storage system. The IBM Storwize V7000 Unified system supports both block protocols and file protocols. NDMP is an open protocol for managing data stored on networked file servers. The NDMP future development is under the direction of the Storage Networking Industry Association (SNIA), which has a work group for NDMP.Executive summaryThis technical report provides details on configuring and enabling the NDMP with IBM®Storwize® V7000 Unified system and enabling CommVault Simpana NDMP-specific settings andfunctionality.CommVault Simpana backup and recovery software for NDMP systems provides easy-to-usedata and storage management capabilities that protect data residing on IBM Storwize V7000Unified system. CommVault Simpana software leverages NDMP to deliver a proven dataprotection solution with efficient backup and reliable restore.The IBM Storwize V7000 Unified system supports NDMP version 4. The NDMP function isconfigured and managed on the Storwize V7000 Unified system using the Storwize V7000Unified command-line interface (CLI) from the active management node.

  5. 5. • Basic knowledge of IBM Storwize Unified system • Basic knowledge CommVault Simpana 9.0 • The IBM Storwize Unified appliance must have Storwize V7000 file module software version 1.3 GA or higher.IBM Storwize V7000 Unified systemThe IBM Storwize V7000 Unified system offers simple, unified storage architecture. In an IBMStorwize V7000 Unified system the file module is a clustered system comprised of two units thatprovide file systems for use by network-attached storage. The file module uses the StorwizeV7000 storage system to provide the file module with volumes. Volumes are also provided on thestorage area network (SAN).Figure 1: IBM Storwize V7000 Unified System Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 2
  6. 6. Figure 2: IBM Storwize V7000 Unified architectureThe IBM Storwize V7000 Unified file module software contains both interface-node andmanagement node functions. A management node is used for configuring, administering, andmonitoring a system. An interface node connects a system to an Internet Protocol (IP) network.The Storwize V7000 Unified software performs the following functions for the host systems thatare attached to the Storwize V7000 Unified system: • Creates a single pool of storage • Provides logical unit virtualization • Manages logical volumes • Mirrors logical volumes Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 3
  7. 7. The Storwize V7000 Unified system also provides the following functions: • Large scalable cache • Copy services − IBM Tivoli® Storage FlashCopy® Manager (point-in-time copy) function, including thin-provisioned FlashCopy to make multiple targets affordable − Metro Mirror (synchronous copy) − Global Mirror (asynchronous copy) − Data migration • Space management − IBM System Storage® Easy Tier™ to migrate the most frequently used data to higher performing storage − Metering of service quality when combined with IBM Tivoli® Storage Productivity Center − Thin-provisioned logical volumesThis offers great flexibility to customers in meeting their storage needs that can either be file-based or block-based.Storwize V7000 Unified system NDMP overviewIBM Storwize V7000 Unified system supports NDMP version 4. NDMP is a network-basedprotocol used by data management applications primarily for backing up and restoring the filescontained within a network-attached storage (NAS) system, such as IBM Storwize V7000 Unifiedsystem.The Storwize V7000 Unified system NDMP feature provides the capability to backup and restorethe files and directories within file systems of Storwize V7000 Unified system. The granularity ofbackup is at the directory level. NDMP supports the concept of a full backup and an incrementalbackup. A full backup backs up all files and directories specified by Storwize V7000 UnifiedNDMP feature. An incremental backup backs up those files and directories that have changedsince the last full backup. Incremental backups are cumulative.A cumulative incremental backup backs up the files that are specified in the backup selections listthat have changed since the last full backup. All files are backed up, in the event no previousbackup has been finished. Cumulative incremental backups occur automatically according to thescheduled criteria. A complete restore requires the last full backup and the last cumulativeincremental backup.A differential incremental backup backs up the files that have changed since the last successfulincremental (differential or cumulative) or full backup. All files are backed up if no previousbackup has been done. Differential incremental backups occur automatically according to thescheduled criteria. A complete restore requires the last full backup, the last cumulativeincremental backup, and all differential incremental backups that have occurred since the last fullbackup.

  8. 8. Storwize V7000 Unified supported NDMP physical configurationThere are two primary NDMP configurations that can be used with the Storwize V7000 Unifiedsystem. • Two-way (or remote) NDMP • Three-way NDMPThe following sections describe the two-way (or remote) and three-way NDMP configurations indetail. Two-way (or remote) Storwize V7000 Unified NDMP configuration The two-way NDMP consists of an external data management application, such as CommVault Simpana, running on a server external to the Storwize V7000 Unified system. The data management application system has some form of storage hierarchy, such as a tape library or tier 2 disk storage that it manages for the storage of backup data. In addition to the external data management application (CommVault Simpana) system, an Ethernet network exists that connects the data management application system to the Storwize V7000 file modules on which the NDMP server is running. NDMP control and data traffic flow across this network, between the external data management application system and the Storwize V7000 Unified file modules, on which the NDMP server is running. Recommendation: The recommendation is that this network be a high speed 10 Gb Ethernet network to handle the volume of data being backed up or restored. However, nothing prevents this network from being a 1 Gb Ethernet network. Figure 3 shows an example of a two-way Storwize V7000 Unified NDMP configuration. It includes an external data management application (CommVault Simpana) running on a server external to the Storwize V7000 Unified system. The data management application server has an IBM System Storage TS7650G ProtecTIER® Deduplication Gateway attached to it through an 8 Gbps Fibre Channel (FC) SAN. The System Storage TS7650G ProtecTIER Deduplication Gateway has an IBM System Storage DS5000 storage controller attached to it through 8 Gbps FC links, which in turn has some number of IBM System Storage DS5000 disk storage expansion units attached to it through 8 Gbps FC links. The data management application is connected to a 10 Gbps Ethernet network to which the Storwize V7000 Unified file modules are attached. In Figure 3, the lines are intended to show the type and speed of the connections between the various physical components and do not necessarily represent the actual number of physical links.

  9. 9. Figure 3: Two-way (remote) Storwize V7000 NDMP configuration Three-way Storwize V7000 Unified NDMP configuration In a three-way Storwize V7000 Unified NDMP configuration, an NDMP tape server is installed on a server external to the Storwize V7000 Unified system and separate from the server on which the CommVault Simpana data management application is running. Some form of storage devices, such as a virtual tape library or real tape library and tape drives are attached to the server running the NDMP tape server. The NDMP controls the traffic flow between the CommVault Simpana data management application system and the Storwize V7000 Unified file modules. NDMP data traffic flows between the Storwize V7000 Unified file modules and the NDMP tape server. In this scenario, only NDMP control traffic is flowing between the CommVault Simpana data management application system and the Storwize V7000 Unified file modules. Therefore, the CommVault Simpana data management application system does not need to be on a high- speed network. The CommVault Simpana (data management application) system can use a lower speed, 1 Gbps Ethernet, network to connect the Storwize V7000 Unified file modules and the external server on which the NDMP tape server is running. However, NDMP data traffic (the actual data being backed up or restored) is flowing between the Storwize V7000 Unified file modules and the external server on which the NDMP tape server is running. Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 6
  10. 10. Recommendation: It is recommended that the Ethernet network between the NDMP tape server and the Storwize V7000 Unified file modules running the NDMP server be a high- speed 10 Gbps Ethernet network. Figure 4 shows an example of an NDMP three-way configuration. In this example, the Storwize V7000 Unified file modules (used for file serving) and the data management applications are connected on a 1 Gbps Ethernet network. Storwize V7000 Unified file modules used for NDMP backup and restore, are also connected to a 10 Gbps Ethernet network along with the NDMP tape server. The server on which the NDMP tape server is running is connected to an 8 Gbps FC SAN along with an IBM System Storage TS3500 tape library with some FC-attached tape drives, such as IBM Linear Tape-Open data cartridges, Generation 3, Generation 4, or Generation 5 tape drives. Figure 4: Three-way Storwize V7000 NDMP configuration Fundamentals of Storwize V7000 Unified NDMP feature The following points explain the fundamentals of Storwize V7000 Unified NDMP features: An NDMP version 4 compliant data server is available on file modules of the Storwize Unified storage system. There is a provision to create both the file modules that will be part of the ndmp node group configuration. Both file modules are paired with the network group IP addresses that can be assigned to a specific network port. This network port is associated with the NDMP service.Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 7
  11. 11. The NDMP server running on a file module provides for both data and control connections to servers external to the Storwize V7000 Unified storage system on which a data management application (CommVault Simpana) is running. The ability to configure the NDMP parameters for file modules (the NDMP_NODE_GROUP) is provided through Storwize V7000 Unified CLI commands that are run from the file module, which stores the NDMP configuration parameters in the Samba Registry. In addition to the Storwize V7000 Unified CLI commands available to store and retrieve NDMP configuration parameters, a set of CLI commands are provided to view NDMP session information and NDMP log information, and to stop currently running NDMP sessions. An NDMP backup session provides a backup of a specific directory in an IBM General Parallel File system (IBM GPFS™) and all files and subdirectories contained within it. Besides the basic data of the files and directories, all extended GPFS attributes are saved for every file and directory. In order to provide the provision to back up a directory structure at a given point in time, a snapshot is used and it is actually the snapshot of the directory structure that is backed up. This snapshot also accounts for files that might be open or in use during the backup as a point-in-time representation of the file that is backed up by NDMP. An NDMP restore session restores all the files and directories in the proper structure of subdirectories, and so on. In addition to the actual file contents, the GPFS extended attributes are also restored. Storwize V7000 Unified NDMP command-line configuration The following Storwize V7000 Unified CLI commands (shown in Table 1) are available for configuring, monitoring, and managing the NDMP configuration parameters and NDMP sessions.# Storwize V7000 Unified CLI command Usage description1 cfgndmp Configure NDMP2 cfgndmpprefetch Configuring NDMP backup prefetch3 lsndmp List NDMP configuration List the actual contents of the NDMP log on the4 lsndmplog given file module5 lsndmpsession List NDMP session information Remove NDMP configuration information for a specified NDMP node group6 rmndmpcfg7 stopndmpsession Stop NDMP session8 lsndmpprefetch List NDMP prefetch configurationTable 1: Storwize V7000 Unified CLI command description Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 8
  12. 12. LAB Storwize V7000 Unified system configuration In the lab: The Storwize V7000 Unified system has one enclosure for block access functionality. The Storwize V7000 Unified system has two file modules that act as management nodes, interface nodes, and storage nodes for file-level access: mgmt001st001, mgmt002st001 The Storwize V7000 Unified system file cluster is defined as: ifs1isv.storage.tucson.ibm.com There are 10 Gb Ethernet cards on each file modules and configured ethX1 to access the bonded ports.

  18. 18. Figure 13: NDMP node group activation summary Storwize V7000 Unified NDMP node group configuration using CLI This section provides the appropriate guidelines to create and configure the Storwize V7000 Unified NDMP node group. • A Storwize V7000 Unified NDMP configuration can be defined only for an NDMP node group. • A Storwize V7000 Unified NDMP node group must be created before any other specific Storwize V7000 Unified NDMP node group configuration parameters can be set. • A Storwize V7000 Unified NDMP node group is created, configured, and activated appropriately, before an NDMP backup or restore can be configured on the CommVault Simpana Data Management Application (DMA) server. To configure the Storwize V7000 Unified NDMP node group: 1. Create an NDMP node group using the --create option of the cfgndmp command on the Storwize V7000 Unified file module. cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --create 2. Attach the newly configured network group, ndmp_nw_group, (refer to the “Storwize V7000 Unified NDMP network group configuration” section) to the newly created Storwize V7000 Unified NDMP node group using the cfgndmp Storwize V7000 Unified CLI command with the --networkGroup option on the file module. cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --networkGroup ndmp_nw_groupImplementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 15
  19. 19. 3. Set the data port range of the NDMP node group using the --dataTransferPortRange option of the cfgndmp command on file module. cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 -- dataTransferPortRange 2048-2098 4. Add the file system mount point paths to the NDMP node group configuration using the -addPaths option of the cfgndmp command on the Storwize V7000 Unified file module. cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --addPaths /ibm/gpfs0,/ibm/gpfs1 5. A default NDMP backup prefetch configuration is assigned to a newly created NDMP node group, with the function deactivated. Optionally, use the cfgndmpprefetch CLI command to change the NDMP backup prefetch configuration and activate the function for improved NDMP backup performance. Refer to the “Configuring Storwize V7000 Unified NDMP backup prefetch” section for more information. 6. Activate the NDMP node group with the –-activate option of the cfgndmp CLI command. cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --activate Note: You can use the lsndmp CLI command with the -ndmpServiceStatus option to verify that NDMP has started on all the nodes in the NDMP node group, on the Storwize V7000 Unified file module. lsndmp -c ifs1isv.storage.tucson.ibm.com [-s] [--ndmpServiceSatus]Figure 14: lsndmp CLI usage Configuring Storwize V7000 Unified NDMP backup prefetch The NDMP backup prefetch function reiterate the directory that is being backed up, reading files in advance to the files actually coming due to be backed up. The prefetch function opens files in the read-only mode and places the files in the file module’s cache for improved backup performance. NDMP backup prefetch is designed to work on files that are less than or equal to 1 MB in size. Restriction: Storwize V7000 Unified NDMP backup prefetch will not work for a file system that has a block size that is greater than 1 MB. To activate the NDMP backup prefetch feature, use the cfgndmpprefetch CLI command with the --activate option. Specify the NDMP node group to enable NDMP prefetch feature with Storwize V7000 Unified NDMP node group, as in the following example on the Storwize V7000 Unified file module.

  20. 20. cfgndmpprefetch -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --activate Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that prefetch for NDMP will be activated when NDMP is activated. To set a limit for the number of applications that can simultaneously use the Storwize V7000 Unified NDMP backup prefetch for a node, (including multiple instances of the same program such as multiple Storwize V7000 Unified NDMP sessions) use the cfgndmpprefetch CLI command with the --appLimit option, as in the following example on the Storwize V7000 Unified file module. cfgndmpprefetch –c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --appLimit 4 Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that the configuration for prefetch for NDMP has been updated. To set a limit for the number of prefetching threads on file module, use the cfgndmpprefetch CLI command with the -numThreads option, as in the following example on the Storwize V7000 Unified file module. cfgndmpprefetch –c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --numThreads 100 Note: The value for the --numThreads option must be a positive integer, greater than 50 and less than or equal to 180. The default value is 100. To display NDMP backup prefetch status information, use the lsndmpprefetch CLI command using the -s or --status option, and optionally adding the -g option to limit display to the specified NDMP node group, as in the following example on the Storwize V7000 Unified file module. lsndmpprefetch –c ifs1isv.storage.tucson.ibm.com –g ndmp_node_grp1 -sImplementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 17

  22. 22. Notes: • IBM Tivoli Storage Manager backup / restore and NDMP backup / restore provide the same basic functionality of backing up or restoring file systems and the directories and files within the file systems. It is not recommended and not supported to have both Tivoli Storage Manager backup restore processing and NDMP backup restore processing being used on the same Storwize V7000 Unified system. • NDMP backups are normally scheduled operations, which can be scheduled at a time when other activity, such as general purpose file serving, is low. If possible, it is recommended to perform NDMP backups during periods when other file serving activity is generally lower, perhaps late in the evening or early in the mornings. • In case the NDMP backup or restore processing significantly interferes with other Storwize V7000 Unified functions, such as network file serving (CIFS, NFS, FTP, HTTP), then consider increasing the processing power and memory configuration of the Storwize V7000 file modules. Many Storwize V7000 Unified functions invoke the GPFS policy engine to evaluate a GPFS policy to determine the list of files to operate on. These include: − Tivoli Storage Manager backup processing − Tivoli Storage Manager HSM processing − NDMP incremental backup processing − Asynchronous replication processing − The runpolicy CLI command and others The GPFS policy engine scans the file system metadata to determine the files that match the criteria specified in the policy. This scan of the file system metadata can generate a significant amount of I/O to the storage systems to read all the file system metadata, especially for file systems containing very large number of files, such as 10s or 100s of millions of files. Therefore, it is recommended not to start all the Storwize V7000 Unified functions at exactly the same time, but instead stagger them over time. Considerations for CommVault Simpana data management application for Storwize V7000 Unified system NDMP backup • Obtain either the IP address or host name for the file module to be used for a given NDMP session. − Host name: Configure a DNS server with a common host name mapped to all of the IP addresses that are associated with the network group that is associated with the NDMP node group. If this hostname is used, any of the file modules that are associated with the NDMP node group can be assigned based on a round robin IP address assignment from the DNS server. − IP address: Submit the lsnwinterface CLI command using the -x option on the file module of the Storwize V7000 Unified system and choose an appropriate IP address or multiple IP addresses if multiple backup policies are to be run simultaneously. This method is useful if multiple NDMP backup policies are used Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 19
  23. 23. and you want to distribute the NDMP workload across file modules and ensure that the same file module will not be used for all of the backup policies that will be run from the DMA server. • Configure the CommVault Simpana 9.0 DMA server with the configuration parameters of the NDMP server for the file module that are available to perform NDMP services, including the username and password associated with the NDMP node group. If a port other than 10000 was selected for the NDMP control port, then that control ports information needs to be configured on the DMA server. Monitoring NDMP session on Storwize V7000 Unified system Note: Read this information after configuring CommVault Simpana NDMP configuration and staging appropriate Storwize V7000 Unified NDMP backup or restore. Refer to the “CommVault Simpana NDMP configuration” section for more information. • The lsndmpsession CLI command enables to monitor the NDMP session on the Storwize V7000 Unified system. Use the -n or -nodes option to view NDMP sessions running on specified file module or with the -g or --nodeGroupName option to view NDMP sessions running on specified NDMP node groups. Only file modules can be specified when using the -n or --nodes option. Multiple file modules and multiple node groups in a list must be separated with commas. If no file modules or node groups are specified, the output displays the information for all the file modules in the cluster. To determine the file modules that are running the NDMP sessions for an NDMP node group, submit the following command that shows the file module that has NDMP sessions running and the sessions that are running on the nodes: lsndmpsession –c ifs1isv.storage.tucson.ibm.com -n mgmt001st001 Or lsndmpsession –c ifs1isv.storage.tucson.ibm.com –g ndmp_node_grp1 • Use the Storwize V7000 Unified CLI lsndmpsession command with the -i or --sessionID option to view the verbose information of the NDMP session identified by the specified session ID (sid) running on the specified file module. In the following example, the sid 1284990 is specified. Use the Storwize V7000 CLI lsndmpsession command with the -i or --sessionID option to view the verbose information of the NDMP session identified by the specified session ID (sid) running on the specified file module. lsndmpsession –c ifs1isv.storage.tucson.ibm.com -n mgmt001st001 -i 1284990Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 20
  24. 24. Monitoring NDMP log information on Storwize V7000 Unified system You can view Storwize V7000 Unified NDMP log using the lsndmplog CLI command. • Use the Storwize V7000 Unified CLI lsndmplog command with the -n or --nodes option to view all the NDMP log information related to the specified file module. In the following example, the file module mgmt001st001 is specified: lsndmplog -c st001.vsofs1.com -n mgmt001st001 • Use the Storwize V7000 Unified CLI lsndmplog command with the -l or --lines option to view the most recent lines of the NDMP log information related to the specified interface node. In the following example, the node int005st001 and 25 lines are specified: lsndmplog -c st001.vsofs1.com -n mgmt001st001 -l 25 • Use the Storwize V7000 Unified CLI lsndmplog command with the -o or --outputLogFilePath option to save the log file as a temporary file, as in the following example: lsndmplog -c st001.vsofs1.com -n mgmt001st001 -o /ibm/gpfs0/ndmplog.outImplementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 21

Types of CommVault Simpana 9.0 backup The different types of CommVault Simpana 9.0 backup are: • Full backup: A full backup contains all the data that comprises a subclients contents. You can also perform a backup at the backup-set or instance-level, and apply to all of the subclients within the selected backup set or instance. • Incremental backup: An incremental backup contains only data that is new or has changed since the last backup, regardless of the type. On an average, incremental backup consume far less storage space and less burden on resources, than full backup. Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 53
  57. 57. • Differential backup: A differential backup contains only the data that is new or has changed since the last full backup. Similar to incremental backup, differential backups, on an average, consume less storage space and less burden on resources, than full backup. Initiating CommVault Simpana 9.0 full Storwize V7000 NDMP backup To initiate CommVault Simpana 9.0 full Storwize V7000 Unified NDMP backup: 1. In the CommCell browser, right-click the newly-created subclient and click Backup, as show in the Figure 64.Figure 64: Creating a full Storwize V7000 Unified NDMP backup Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 54

  59. 59. 3. On the Data Path tab select the correct media agent, library, drive pool, and drive and then click OK, as shown in Figure 66.Figure 66: Specifying advanced backup options 4. Track the progress of the backup job from the Job Controller window. For the stand-alone drive, you are prompted to load a specific cartridge into the drive. If you are using a library, you will not receive this prompt. The system loads the tapes automatically and therefore the cartridges need to be labeled appropriately. This enables to locate the correct cartridge for a restore job, if necessary. 5. When the backup is complete, the Job Controller displays the text Completed. After running a backup, view the backup history to verify the backup data.

  60. 60. The CommVault Simpana 9.0 incremental / differential Storwize V7000 Unified NDMP backup considerations There are specific Storwize V7000 Unified NDMP environment variables, which are treated as parameters and can be passed to the NDMP server from data management applications performing NDMP backups. The following two parameters can be configured through data management applications. • BACKUP_GROUP_NAME: This is the name of a backup group where all the backup directories within the backup group share the same Storwize V7000 Unified snapshot. − Note 1: The way to set this environment variable is to have a line similar to the following line in the backup policy: SET BACKUP_GROUP_NAME=NDMP_EXISTING_snap1 − Note 2: If the BACKUP_GROUP_NAME begins with NDMP_EXISTING, then it is assumed that the Storwize V7000 Unified system is configured to use a snapshot, which has a name corresponding to this environment variable value. In this special case, it is also assumed that the user will delete the corresponding snapshot manually. − Note 3: The maximum length of the backup group name is 32 characters (inclusive of a possible NDMP_EXISTING). • BACKUP_GROUP_EXPIRATION: This parameter helps to configure the amount of valid time that the snapshot is associated with BACKUP_GROUP_NAME. After the age of the snapshot has surpassed the expiration value, a new snapshot will be taken and all new NDMP backup sessions associated with BACKUP_GROUP_NAME will use the new snapshot. This Storwize V7000 Unified NDMP parameter is very important to effectively schedule incremental or differential backup which has less than 1 hour incremental and differential backup expiration schedule time. − Note 1: The way to set this environment variables is to have a line similar to the following line in the backup policy: SET BACKUP_GROUP_EXPIRATION = 1_DAY − Note 2: The following values are acceptable for this environment variable: • 0_SEC … 60_SEC • 0_MIN … 60_MIN • 0_HOUR … 168_HOUR • 0_ DAY … 31_DAY • 0_MONTH … 12_MONTH − Note 3: If no value is given for the expiration, the default will be 1 hour. − Note 4: If the user wants to ensure that a separate snapshot is taken for every directory, then an expiration value of 0_SEC should be specified.Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 57

  68. 68. 3. View the backup job history information that is displayed in CommVault Simpana 9.0Figure 74: Backup job history informationStorwize V7000 Unified NDMP restore using CommVault Simpana 9.0Using CommVault Simpana 9.0, you can restore NDMP backup data to Storwize V7000 Unifiedsystem, on both two-way Storwize V7000 Unified NDMP and three-way Storwize V7000 UnifiedNDMP configurations. Direct Access Restore Direct Access Restore optimizes the restore operation by allowing the NDMP client to directly access backed up data, anywhere in a tape set, without having to traverse the tape set sequentially. In a normal restore operation, a large portion of the data from the backup that included the file must be read. In a Direct Access Restore, only the portion of the tape which contains the data to be restored is read. This option is available for each of the Storwize V7000 NDMP restore types and can save significant time in the restore operation. When to use Direct Access Restore While each environment is different, with many variables that can affect restore efficiency (making it impossible to define when a Direct Access Restore can yield best performance), the following guidelines might be of assistance until you can evaluate the speed appropriately in a specific environment: • Generally, the smaller the percentage of a given backup that are restoring, the greater will be the performance value of using Direct Access Restore. As the percentage rises above 30% to 40%, a non-Direct Access Restore becomes the preferred choice. • A three-way restore involves more communication overhead between the library and the Storwize V7000 Unified system being restored, and thus sequentially reading the tape becomes the more-efficient choice sooner. Because of this, you might find that a non-Direct Access Restore is the preferred choice even when the percentage of a given backup being restored is under 30%. Efficient non-Direct Access Restore Even if you are not using direct access restores, it is still possible to optimize restore performance. For instance, if the most-recent copy of the data that you want to restore was backed up by an incremental or differential backup, the restore only reads the archive file Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using CommVault Simpana © Copyright IBM Corporation, 2011. 65
  69. 69. from that differential or incremental backup, instead of reading the archive files back to the last full backup.

  73. 73. Appendix A: Glossary • IBM Storwize V7000 Unified system – Built on IBM high-performance computing experience, and designed to support both block and file storage protocols, Storwize V7000 Unified system provides the performance, high availability, single management interface, and functionality that are essential to address strategic storage requirements. • Network Data Management Protocol (NDMP) – An industry standard protocol created to ease the process of integrating backup and restore for NAS with data protection software such as NetBackup. The NDMP is the data transfer protocol and one piece of the overall data protection solution. For more information about the NDMP protocol and the NDMP standards group, visit http://www.ndmp.org/info/faq.shtml. • Two-way (or remote) Storwize V7000 Unified NDMP – NDMP configuration supported by Storwize V7000 Unified storage system. The two-way NDMP consists of an external data management application, such as CommVault Simpana, running on a server external to the Storwize V7000 Unified storage system. The data management application has some form of storage hierarchy such as a tape library or Tier 2 storage that it manages for storing of backuped data. • Three-way Storwize V7000 Unified NDMP – NDMP configuration supported by Storwize V7000 Unified storage system. In a three-way Storwize V7000 Unified NDMP configuration, an NDMP tape server is installed on a server external to the Storwize V7000 Unified storage system and separate from the system where CommVault Simpana data management application is running. • CommVault Simpana – NDMP Data Management Application used to backup Storwize V7000 Unified data, using Storwize V7000 Unified NDMP technology. • Direct access recovery (DAR) – CommVault Simpana uses DAR to restore a directory or individual files from a backup image. DAR can greatly reduce the time it takes to restore files and directories. DAR is enabled by default (no configuration is required).
