Abstract Network Data Management Protocol (NDMP) is an open protocol for managing data stored on networked servers. This document provides the best practices guide for implementing IBM SONAS NDMP backup solution using CommVault Simpana. The NDMP future development is under the direction of the Storage Networking Industry Association (SNIA), which has a work group for NDMP.

SONAS NDMP

IBM® Scale Out Network Attached Storage (SONAS) is designed to address the new storage challenges posed by the continuing explosion of data. Leveraging mature technology from IBM’s high-performance computing experience, and based upon IBM General Parallel File System (IBM GPFS™), SONAS is an easy-to-install, turnkey, modular, scale out network-attached storage (NAS) solution that provides the performance, clustered scalability, high availability, and functionality that are essential to meet strategic Petabyte Age and cloud-storage requirements.

The high-density, high-performance SONAS can help organizations consolidate and manage data affordably, reduce crowded floor space, and reduce management expense associated with administering an excessive number of disparate storage systems. With its advanced architecture, SONAS virtualizes and consolidates multiple filers into a single, enterprise-wide file system, which can translate into reduced total cost of ownership (TCO), reduced capital expenditure, and enhanced operational efficiency.

This paper is part of the SONAS Network Data Management Protocol (NDMP) information set and is intended for the System Administrator implementing a backup strategy with CommVault Simpana 9.0. The System Administrator should be familiar with backup and restore operations and with the basic administration of CommVault Simpana 9.0.

Overview of SONAS NDMP NDMP is a network-based protocol used by data management applications primarily for backing up and restoring the files contained within a NAS system such as SONAS. The SONAS support the Network Data Management Protocol (NDMP) version 4.

The SONAS NDMP implementation provides the capability to back up and restores the file systems with the SONAS system using NDMP. The granularity of backup is at the directory level. NDMP supports the concept of a full backup and an incremental backup. A full backup backs up all files and directories specified to be backed by SONAS NDMP. An incremental backup backs up those files and directories that have changed since the last full backup. Incremental backups are cumulative.

A cumulative incremental backup backs up the files that are specified in the backup selections list that have changed since the last full backup. All files are backed up if no previous backup has been done. Cumulative incremental backups occur automatically according to schedule criteria. A complete restore requires the last full backup and the last cumulative incremental backup.


2

A differential incremental backup backs up the files that have changed since the last successful incremental (differential or cumulative) or full backup. All files are backed up if no previous backup has been done. Differential incremental backups occur automatically according to schedule criteria. A complete restore requires the last full backup, the last cumulative incremental backup, and all differential incremental backups that have occurred since the last full backup.

SONAS NDMP supported physical configuration There are two primary methods in which NDMP can be used as an interface with SONAS.

1. Two-way (or remote) NDMP

2. Three-way NDMP

The following sections describe the two-way (or remote) and three-way NDMP configurations in depth.

Two-way (or remote) SONAS NDMP configuration

The two-way NDMP consists of an external data management application, such as CommVault Simpana, running on a server external to the SONAS 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.

In addition to the external data management application (CommVault Simpana), an Ethernet network exists that connects the data management application to the SONAS interface nodes on which the NDMP server is running. NDMP control and data traffic flow across this network between the external data management application and the SONAS interface nodes on which the NDMP server is running.

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.

The Figure 1 shows an example of a two-way SONAS NDMP configuration. It includes an external data management application (CommVault Simpana) running on a server external to the SONAS system. The data management application has an IBM System Storage® TS7650G ProtecTIER® Deduplication Gateway attached to it through an 8 Gbps Fibre Channel (FC) storage area network (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® DS5020 disk storage expansion units attached to it through 8 Gbps FC links. The data management application connected to a 10 Gbps Ethernet network, to which the SONAS interface nodes are attached. In Figure 1, the lines are intended to show the type and speed on the connections between the various physical components and do not necessarily represent the actual number of physical links.

Figure 1: An example of a two-way SONAS NDMP configuration

Three-way SONAS NDMP configuration

In three-way SONAS NDMP implementation, an NDMP tape server is installed on a server external to the SONAS 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 control traffic flows between the CommVault Simpana data management application and the SONAS interface nodes and NDMP data traffic flows between the SONAS interface nodes and the NDMP tape server. In this scenario, as only NDMP control traffic is flowing between the CommVault Simpana data management application and the SONAS interface nodes, the CommVault Simpana data management application does not need to be on a high-speed network. The CommVault Simpana (data management application) can use a lower speed 1 Gbps Ethernet network to connect the SONAS interface nodes 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 SONAS interface nodes and the external server on which the NDMP tape server is running. Therefore, it is recommended that the Ethernet network between the NDMP tape server and the SONAS interface nodes running the NDMP server be a high-speed 10 Gbps Ethernet network.

The Figure 2 shows an example of an NDMP three-way configuration. In this example, the SONAS interface nodes (used for file serving) and the data management applications are on a 1 Gbps


4

Ethernet network. Other SONAS interface nodes, used for NDMP backup and restore, are on 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 2: An example of NDMP three-way configuration

Fundamentals of SONAS NDMP feature The following points explain the fundamentals of SONAS NDMP features:

• An NDMP version 4 compliant data server is available on every interface node of the SONAS system. There is a provision to create a set of interface nodes that will be part of an NDMP_NODE_GROUP. These set of interface nodes is paired with network group IP addresses that can be assigned to a specific network port. This network port is associated with the NDMP service.

• The NDMP server running on an interface node provides for both data and control

connections to servers external to the SONAS system on which a data management appliance is running.


5

• The ability to configure the NDMP parameters for this set of interface nodes (the

NDMP_NODE_GROUP) is provided through SONAS command-line interface (CLI) commands that are run from the management node, which stores the NDMP configuration parameters in the Samba Registry.

• In addition to the SONAS CLI commands available to store and retrieve NDMP configuration parameters, a set of CLI commands are provided that allow to view NDMP session information and NDMP log information, and to stop currently running NDMP sessions.

• An NDMP backup session will provide backup of a specific directory in a GPFS file system

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 may 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. In addition to the actual file contents, the GPFS extended attributes are also restored.

SONAS NDMP command-line configuration

The following SONAS CLI commands (shown in Table 1) are available for configuring, monitoring, and managing the NDMP configuration parameters and NDMP sessions:

Table 1: SONAS CLI command description

ISV LAB SONAS system configuration In the ISV lab:

• The SONAS appliance has one management node: mgmt001st001 • The SONAS appliance has five interface nodes: int001st001, int002st001,

int003st001,int004st001,int005st001 • The SONAS cluster is defined as: st001.vsofs1.com • There is a 10 Gb Ethernet card on each interface node and configured ethX0 to access

the bonded ports

(Refer to “Appendix B: Materials used in the lab setup” for more information)

# SONAS CLI command Is used to

1 cfgndmp Configure NDMP

2 cfgndmpprefetch Configuring NDMP backup prefetch

3 lsndmp List NDMP configuration

4 lsndmplog List the actual contents of the NDMP log on the given interface node

5 lsndmpsession List NDMP session information

6 rmndmpcfg Remove NDMP configuration information for a specified NDMP node group

7 stopndmpsession Stop NDMP session

8 lsndmpprefetch List NDMP prefetch configuration


7

SONAS NDMP network group configuration This section provides the guidelines to create and configure network group that includes all of the interface nodes that will service NDMP requests for the NDMP node group.

• Create a network group comprising three interface nodes using mknwgroup SONAS CLI command on SONAS management node.

mknwgroup ndmp_nw_group int001st001,int002st001,int003st001

Validate the network group using the lsnwgroup SONAS CLI command on SONAS management node.

Note: If you want to add an interface node to an existing network group, use the chnwgroup command. For example, you could add an interface node named int005st001 to the network group ndmp_group as follows:

chnwgroup ndmp_nw_group --add int005st001

• Create a network with configurable IP addresses using the mknw SONAS CLI command on SONAS management node.

mknw 17.0.0.0/24 0.0.0.0/0:17.0.0.1 --add 17.0.0.100,17.0.0.101, 17.0.0.102, 17.0.0.103

Note: Visit the URL: http://oav.net/mirrors/cidr.html to figure out the Classless Inter-Domain Routing (CIDR). In this case, the team used 23. mknw 17.0.0.0/24…

Validate the newly created network using the lsnw SONAS CLI command on SONAS management node.

• Attach the newly created network group, ndmp_nw_group, to the newly created network using the attachnw SONAS CLI command on SONAS management node.

attachnw 17.0.0.0/24 ethX0 -g ndmp_nw_group


8

SONAS NDMP node group configuration This section provides appropriate guidelines to create and configure the SONAS NDMP node group.

• A SONAS NDMP configuration can be defined only for an NDMP node group. • A SONAS NDMP node group must be created before any other specific SONAS NDMP node

group configuration parameters can be set. • A SONAS NDMP node group is created, configured, and activated appropriately, before an NDMP

backup or restore can be configured on the CommVault Simpana DMA (Data Management Application) server.

Note: The SONAS NDMP configuration parameters of a single interface node cannot be changed individually.

• Create an NDMP node group using the “--create” option of the “cfgndmp” command on SONAS management node.

cfgndmp -c st001.vsofs1.com ndmp_node_grp1 --create

• Attach the newly configured network group, ndmp_nw_group, refer to “SONAS NDMP network group configuration”, to the newly created SONAS NDMP node group using the cfgndmp SONAS CLI command with the --networkGroup option on the SONAS management node.

cfgndmp -c st001.vsofs1.com ndmp_node_grp1 --networkGroup ndmp_nw_group

• Set the data port range of the NDMP node group using the --dataTransferPortRange option of the cfgndmp command on SONAS management node.

cfgndmp -c st001.vsofs1.com ndmp_node_grp1 --dataTransferPortRange 2048-2098

• Add file system mount point paths to the NDMP node group configuration using the -addPaths option of the cfgndmp command on the SONAS management node.

cfgndmp -c st001.vsofs1.com ndmp_node_grp1 --addPaths /ibm/isvtsm,/ibm/isvvm,/ibm/isvora,/ibm/isv64

• 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 SONAS NDMP backup prefetch” section for more information.

• Activate the NDMP node group with the –-activate option of the cfgndmp CLI command.

cfgndmp -c st001.vsofs1.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 of the nodes in the NDMP node group, on the SONAS management node.

lsndmp -c st001.vsofs1.com [-s] [--ndmpServiceSatus]

Figure 3: An example of lsndmp -s option result

Configuring SONAS 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 interface node'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: SONAS NDMP backup prefetch will not work for a file system that has 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 NDMO prefetch feature with SONAS NDMP node group, as in the following example on the SONAS management node.

cfgndmpprefetch -c st001.vsofs1.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 SONAS NDMP

backup prefetch for a node, (including multiple instances of the same program such as multiple SONAS NDMP sessions) use the cfgndmpprefetch CLI command with the -applimit option, as in the following example on the SONAS management node.

cfgndmpprefetch –c st001.vsofs1.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 per interface node, use the

cfgndmpprefetch CLI command with the -numThreads option, as in the following example on the SONAS management node.

cfgndmpprefetch –c st001.vsofs1.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


10

display to the specified NDMP node group, as in the following example on the SONAS management node

lsndmpprefetch –c st001.vsofs1.com –g ndmp_node_grp1 -s

Table 2: Concurrent SONAS NDMP backup and restore usage with other SONAS functions

Notes:

1. 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 SONAS system.

2. 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 recommend performing


12

NDMP backup during periods when other file serving activity is generally lower, perhaps late in the evening or early in the mornings.

3. In case, the NDMP backup or restore processing significantly interferes with other SONAS functions, such as network file serving (CIFS, NFS, FTP, HTTP) then please consider increasing the processing power and memory configuration of the SONAS interface nodes or should consider isolating NDMP processing to dedicated SONAS interface nodes. Many SONAS 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 hierarchical storage management (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 which files 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 that all of these functions not be started at exactly the same time, but instead these SONAS functions be staggered over time.

You need to take care of the following considerations for CommVault Simpana 9.0 DMA SONAS NDMP backup • Obtain either the IP address or host name for the interface node to be used for this NDMP

session. − Host Name: Configure a DNS server with a common hostname 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 interface nodes 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 management node of the SONAS system and choose an 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 and you want to distribute the NDMP workload across multiple interface nodes and ensure that the same interface node 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 interface nodes 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 port's information needs to be configured on the DMA server.

Monitoring NDMP session on SONAS system

Note: Read this information after configuring CommVault Simpana NDMP configuration and staging appropriate SONAS NDMP backup or restore. Refer to the “CommVault Simpana NDMP configuration” section for more information

• The lsndmpsession CLI command enables to monitor NDMP session on SONAS system. Use -n or -nodes option to view NDMP sessions running on specified interface nodes or with the -g or --nodeGroupName option to view NDMP sessions running on specified NDMP node groups.

Only interface nodes can be specified when using the -n or --nodes option. Multiple nodes and multiple node groups in a list must be separated with commas. If no nodes or node groups are specified, the output displays information for all of the interface nodes in the cluster. To determine which interface nodes are running NDMP sessions for an NDMP node group, submit the following command that shows which interface nodes have NDMP sessions running and which sessions are running on the nodes:

lsndmpsession –c st001.vsofs1.com -n int005st001

Or

lsndmpsession –c st001.vsofs1.com –g ndmp_node_grp1

Figure 4: An example of lsndmpsession CLI command usage

• Use the SONAS 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 interface node. In the following example, the sid 1284990 is specified. Use the SONAS 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 interface node.

lsndmpsession –c st001.vsofs1.com -n int005st001 -i 1284990

Figure 5: An example of lsndmpsession CLI command usage with -i option


14

Monitoring NDMP log information on SONAS system

You can view SONAS NDMP log using the lsndmplog CLI command.

• Use the SONAS CLI lsndmplog command with the -n or --nodes option to view all of the NDMP log information related to the specified interface node. In the following example, the node int005st001 is specified:

lsndmplog -c st001.vsofs1.com -n int005st001

• Use the SONAS 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 int005st001 -l 25

• Use the SONAS 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 int001st001 -o /ibm/gpfs0/ndmplog.out

SONAS NDMP backup using CommVault Simpana 9.0 NDMP essentials This section illustrates SONAS NDMP essential backup details and how to configure the SONAS NDMP differential and incremental backup with CommVault Simpana 9.0

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 subclient's 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 media and place, less of a burden on resources, than full backup.

• 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 media and place, less of a burden on resources, than full backup.


48

Initiating CommVault Simpana 9.0 full SONAS NDMP backup

To initiate CommVault Simpana 9.0 full SONAS NDMP backup:

1. In the CommCell browser, right-click the newly-created subclient and select Backup to continue.

50

3. On the Data Path tab select the correct MediaAgent, library, drive pool, and drive and click OK to

continue as shown in Figure 62

Figure 61: 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 appropriately labeled. 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.


51

The CommVault Simpana 9.0 incremental / differential SONAS NDMP backup considerations

There are specific SONAS 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 SONAS 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 begins with NDMP_EXISTING then it is

assumed that the SONAS system 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 SONAS 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.

SONAS NDMP restore using CommVault Simpana 9.0

Using CommVault Simpana 9.0, you can restore NDMP backup data to SONAS system, on both two-way SONAS NDMP and three-way SONAS NDMP 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 SONAS 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 percent, a non-Direct Access Restore becomes the preferred choice.

• A three-way restore involves more communication overhead between the library and the SONAS system being restored, and thus sequentially reading the tape becomes the more efficient choice sooner. Because of this, you may find that a non-Direct Access Restore is the preferred choice even when the percentage of a given backup being restored is under 30 percent.

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 from that differential or incremental backup, instead of reading the archive files back to the last full backup.

Appendix A: Glossary

• IBM Scale Out Network Attached Storage (SONAS) - Build on IBM’s high-performance computing experience, and based upon IBM General Parallel File System (GPFS), scale out network-attached storage (NAS) solution that provides the performance, clustered scalability, high availability, and functionality that are essential to meet strategic Petabyte Age and cloud-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) SONAS NDMP - NDMP configuration supported by SONAS. The

two-way NDMP consists of an external data management application, such as CommVault Simpana, running on a server external to the SONAS 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 SONAS NDMP - NDMP configuration supported by SONAS. NDMP

configuration supported by SONAS. In a three-way SONAS NDMP configuration, an NDMP tape server is installed on a server external to the SONAS system and separate from the system where CommVault Simpana data management application is running.

• CommVault Simpana - NDMP Data Management Application used to backup SONAS

data, using SONAS 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).
