  3. 3. Abstract This technical paper provides the best practices guide for implementing IBM Storwize V7000 Unified Network Data Management Protocol (NDMP) backup solution using the Symantec NetBackup software. 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 summaryAs an established market leader in data protection, Symantec NetBackup can provide unparalleled next-generation data protection by minimizing cost and complexity and ensuring greater business continuitywith a solution that unifies desktop, remote office, and data center protection across the entire enterprise.Symantec also supports a wide range of data protection options including NDMP support.The IBM® Storwize® V7000 Unified system supports NDMP version 4. The NDMP function is configuredand managed on the Storwize V7000 Unified system using the Storwize V7000 Unified command-lineinterface (CLI) from the active management node. NDMP alerts are written to the alert log on the StorwizeV7000 Unified active management node.This technical report provides details on configuring NDMP feature of IBM Storwize V7000 Unified systemand enabling Symantec NetBackup NDMP-specific settings and functionality.Intended audienceThis technical report is intended for: • Customers and prospects looking to implement effective NDMP backup solution on IBM Storwize V7000 Unified system using the Symantec NetBackup software • Users and management seeking detailed information to implement NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup softwareScopeThis technical report provides: • Detailed NDMP backup solution implementation on IBM Storwize V7000 Unified system with Symantec NetBackup 7.0.1 • Detailed NDMP backup implementation guide; configuration best practicesThis technical report does not: • Discuss any performance impact and analysis from a user perspective • Replace any official manuals and documents from IBM and Symantec on the products used in the NDMP backup solution Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 3
  4. 4. PrerequisitesThis technical paper assumes familiarity with the following prerequisites: • Basic knowledge of IBM Storwize V7000 Unified system • Basic knowledge Symantec NetBackup 7.0.1 or higher • The IBM Storwize V7000 Unified system 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 IBM StorwizeV7000 Unified system, the file module is a clustered system comprised of two units that provide filesystems for use by network-attached storage (NAS). The file module uses the Storwize V7000 storagesystem to provide the file module with volumes. Volumes are also provided on the storage area network(SAN).Figure 1: IBM Storwize V7000 Unified system Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 4
  5. 5. Figure 2: IBM Storwize V7000 Unified ArchitectureThe IBM Storwize V7000 File Module Software within the Storwize V7000 Unified system contains theinterface-node and management node functions. A management node is used for configuring,administering, and monitoring 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 that attach toStorwize V7000 Unified: • Creates a single pool of storage • Provides logical unit virtualization • Manages logical volumes • Mirrors logical volumesThe 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 Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 5
  6. 6. • 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 customers great flexibility in meeting their storage needs, irrespective of whether file-based orblock-based.Storwize V7000 Unified system NDMP overviewIBM Storwize V7000 Unified system supports the NDMP version 4. NDMP is a network-based protocolused by data management applications primarily for backing up and restoring the files contained within aNAS system, such as IBM Storwize V7000 Unified system.The Storwize V7000 Unified system NDMP feature provides the capability to backup and restore the filesand directories within file systems of the Storwize V7000 Unified system. The granularity of backup is atthe directory level. NDMP supports the concept of a full backup and an incremental backup. A full backupbacks up all files and directories specified by Storwize V7000 Unified NDMP feature. An incrementalbackup backs up those files and directories that have changed since the last full backup. Incrementalbackups are cumulative.A cumulative incremental backup backs up the files that are specified in the backup selections list thathave changed since the last full backup. In the event no previous backup has been finished, all the filesare backed up. Cumulative incremental backups occur automatically according to the scheduled criteria.A complete restore requires the last full backup and the last cumulative incremental backup.A differential incremental backup backs up the files that have changed since the last successfulincremental (differential or cumulative) or full backup. If no previous backup has been done, all files arebacked up. Differential incremental backups occur automatically according to scheduled criteria. Acomplete restore requires the last full backup, the last cumulative incremental backup, and all differentialincremental backups that have occurred since the last full backup.Storwize V7000 Unified supported NDMP physical configurationThere are two primary NDMP configurations that can be used with the Storwize V7000 Unified system. • Two-way (or remote) NDMP • Three-way NDMPThe following sections describe the two-way (or remote) and three-way NDMP configurations in detail. Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 6
  7. 7. Two-way (or remote) Storwize V7000 Unified NDMP configurationThe two-way NDMP consists of an external data management application, such as SymantecNetBackup, running on a server external to the Storwize V7000 Unified system. The datamanagement application system has some form of storage hierarchy, such as a tape library, that itmanages for the storage of backup data.In addition to the external data management application (Symantec NetBackup) system, an Ethernetnetwork exists that connects the data management application system to the Storwize V7000 filemodules on which the NDMP server is running. NDMP control and data traffic flow across thisnetwork, between the external data management application system and the Storwize V7000 Unifiedfile modules on which the NDMP server is running.Recommendation: The recommendation is that this network be a high speed 10 Gb Ethernetnetwork to handle the volume of data being backed up or restored. However, nothing prevents thisnetwork from being a 1 Gb Ethernet network.Figure 3 shows an example of a two-way Storwize V7000 Unified NDMP configuration. It includes anexternal data management application (Symantec NetBackup) running on a server external to theStorwize V7000 Unified system. The data management application server has an IBM SystemStorage® TS7650G ProtecTIER® Deduplication Gateway attached to it through an 8 Gbps FibreChannel (FC) SAN. The System Storage TS7650G ProtecTIER Deduplication Gateway has an IBMSystem Storage DS5000 storage controller attached to it through 8 Gbps FC links, which in turn hassome number of DS5000 disk storage expansion units attached to it through 8 Gbps FC links. Thedata management application is connected to a 10 Gbps Ethernet network to which the StorwizeV7000 Unified file modules are attached. In Figure 3, the lines are intended to show the type andspeed on the connections between the various physical components and do not necessarilyrepresent the actual number of physical links.

  8. 8. 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 Symantec NetBackup data management application is running. Some forms 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 Symantec NetBackup 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 Symantec NetBackup data management application system and the Storwize V7000 file modules. Therefore, the Symantec NetBackup data management application system does not need to be on a high-speed network. The Symantec NetBackup (data management application) system can use a lower speed 1 Gbps Ethernet network to connect the Storwize V7000 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.

  9. 9. Recommendation: It is recommended that the Ethernet network between the NDMP tape server andthe Storwize V7000 unified file modules running the NDMP server be a high-speed 10 Gbps Ethernetnetwork.Figure 4 shows an example of an NDMP three-way configuration. In this example, the StorwizeV7000 Unified file modules (used for file serving) and the data management applications areconnected on a 1 Gbps Ethernet network. Storwize V7000 Unified file modules used for NDMPbackup and restore, are also connected to a 10 Gbps Ethernet network along with the NDMP tapeserver. The server on which the NDMP tape server is running is connected to an 8 Gbps FC SANalong with an IBM System Storage TS3500 tape library with some FC-attached tape drives, such asIBM Linear Tape-Open data cartridges, Generation 3, Generation 4, or Generation 5 tape drives.Figure 4: Three-way Storwize V7000 NDMP configurationFundamentals of Storwize V7000 Unified NDMP featureThe 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 an NDMP_NODE_GROUP. Both the file modules are paired with network group IP addresses that can be assigned to a specific network port. This network port is associated with the NDMP service.

  10. 10. • 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 (Symantec NetBackup) 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 allowing to view NDMP session information and NDMP log information, and stop currently running NDMP sessions.• An NDMP backup session provides 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 is backed up by NDMP.• An NDMP restore session will restore all of the files and directories in the proper structure of subdirectories, and so on.

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 navigates 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 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. cfgndmpprefetch -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --activate Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 18
  19. 19. 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 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 Symantec NetBackup © Copyright IBM Corporation, 2011. 19

  21. 21. 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 backup 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 energy 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 be staggered over time. Considerations for Symantec NetBackup DMA for Storwize V7000 Unified system NDMP backup Obtain either the IP address or host name for the file module to be used for this 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 host name 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 when multiple NDMP backup policies are used 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.

  22. 22. Configure the Symantec NetBackup DMA server with the configuration parameters of the NDMP server for the file module that are available to perform NDMP services, including the user name 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 systemNote: Read this information after configuring Symantec NetBackup NDMP configuration and stagingappropriate Storwize V7000 Unified NDMP backup or restore. Refer to the “Symantec NetBackupNDMP Configuration” section for more information• The lsndmpsession CLI command enables to monitor the NDMP session on Storwize V7000 Unified system. Use -n or -nodes option to view the NDMP sessions running on a specified file module or with the -g or --nodeGroupName option to view the 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 information for all of the file modules in the cluster. To determine the file modules that are running NDMP sessions for an NDMP node group, submit the following command that shows the file modules that have 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 running on the specified file module. lsndmpsession –c ifs1isv.storage.tucson.ibm.com -n mgmt001st001 -i 1284990 Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 22
  23. 23. Monitoring NDMP log information on Storwize V7000 Unified systemYou 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 of the NDMP log information related to the specified file module. In the following example, the file module mgmt001st001 is specified: lsndmplog -c ifs1isv.storage.tucson.ibm.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 ifs1isv.storage.tucson.ibm.com -n mgmt001st001 -l 25• Use the Storwize V7000 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 ifs1isv.storage.tucson.ibm.com -n mgmt001st001 -o /ibm/gpfs0/ndmplog.out Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 23

  64. 64. 12. Click Finish to complete the Storwize V7000 Unified NDMP policy creation.Figure 65: Finalize the Storwize V7000 Unified NDMP backup policy 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 in the backup policy: SET BACKUP_GROUP_NAME=NDMP_EXISTING_snap1 − Note 2: If the BACKUP_GROUP_NAME parameter 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). Implementing an effective NDMP backup solution on IBM Storwize V7000 Unified system using Symantec NetBackup © Copyright IBM Corporation, 2011. 64
  65. 65. • 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 the 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 that 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.

  71. 71. Symantec NetBackup NDMP restoreThis section describes Symantec NetBackup NDMP restore feature. Using Symantec NetBackup Direct Access Recovery (DAR) for NDMP restores By default, Symantec NetBackup for NDMP is configured to use DAR when restoring files or directories. DAR is used differently for file restore when compared to directory restore, as follows: • For each restore of files (not of directories), Symantec NetBackup automatically determines whether the use of DAR speeds up the restore. Symantec NetBackup uses DAR only when it results in a faster restore. • For restore of directories, by default DAR is always used when restoring a subdirectory but never used when restoring the directory containing an entire image. For example, if /vol/vol0 contains the entire image, and /vol/vol0/dir1 is a subdirectory, DAR is used by default when restoring /vol/vol0/dir1. But it is not used when restoring /vol/vol0. For restore of subdirectories, Symantec NetBackup does not attempt to gauge the effectiveness of using DAR. Unless DAR is manually disabled, Symantec NetBackup always uses DAR when restoring subdirectories.

  85. 85. Appendix A: Glossary • IBM Storwize V7000 Unified system – Build 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 – An NDMP configuration supported by Storwize V7000 Unified storage system. The two-way NDMP consists of an external data management application, such as Symantec NetBackup, 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 that it manages for the storage of backup data. • Three-way Storwize V7000 Unified NDMP – An 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 Symantec NetBackup data management application is running. • Symantec NetBackup – NDMP Data Management Application (DMA) used to backup Storwize V7000 Unified data, using Storwize V7000 Unified NDMP technology. • Direct access recovery (DAR) – Symantec NetBackup 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).
