Understanding the CommCell Console

NAS iDataAgent uses the following main components to perform backup and restore operations from the CommCell Console.

Backup Set - collective information of all the data that needs to be backed up for the client.

Subclient - defines the data to be backed up.

Configuring User Defined Backup Sets

A default backup set is created as soon as the NAS client is added. The default backup set includes a default subclient which will backup all the data in the file server.

You can create user defined backup sets to group a set of selected data. A user defined backup set will contain its own default subclient.

Creating a User Defined Backup Set

  1. From the CommCell Browser, navigate to Client Computers | <Client>.
  2. Right-click the <File Server> NAS NDMP and select All Tasks | Create New Backup Set.
      If you create a user defined backup set, you cannot perform incremental or differential backups for any backup set. However, for NetApp NAS NDMP clients, there are no limitations on the type of backups that can be performed for the default backup set.
  3. In the New Backup Set Name box, type a name.
  4. Click OK.

Creating An On Demand Backup Set

On Demand backups allow content to be specified as an external input at the time of initiating a backup. Whereas traditional backups are performed using subclients, which contain fixed content configured prior to performing the operation, On Demand backups allow you to specify content each time you perform a backup.

Creating a Content File

Content for On Demand backups is defined through a Content File, which is a text file that defines the location of the data that you want to protect. The Content File contains the fully qualified paths from the root directory to the directories and devices which you want to back up. The Content File must be placed on the CommServe or the MediaAgent.

The following examples demonstrate the specific format for entries in the Content File for NetApp File Server:

/vol/vol0/Dir1

/vol/vol0/Dir2

The following examples demonstrate the specific format for entries in the Content File for Celerra File Server

/fs1/Dir1

/fs1/Dir2

Do not use filters, wildcards, or regular expressions in the Content File.

Using the Content File Stored on a MediaAgent

If you want to use the content file stored on a MediaAgent, create the following registry key on the MediaAgent:

  1. From the CommCell Browser, navigate to Storage Resources | MediaAgents.
  2. Right-click the <MediaAgent> in which you want to add the registry key, and then click Properties.
  3. Click the Registry Key Settings tab.
  4. Click Add.
  1. In the Name box, type OnDemandLocalFilePath.
  2. In the Location list, type HKEY_LOCAL_MACHINE\SOFTWARE\CommVault Systems\Galaxy\Instance<xxx>\

    If you are creating this registry key on a Unix client, in the Location list, type /etc/CommVaultRegistry/Galaxy/Instance<xxx>/NAS/.properties

  1. In the Type list, select REG_DWORD.
  2. In the Value field, type the full path of the content file.
  3. Click OK.

Creating On Demand Backup Set

After creating the Content File defining the content to be backed up, create an On Demand Backup Set.

  1. From the CommCell Browser, navigate to Client Computers | <Client>.
  2. Right-click the <File Server> NAS NDMP and select All Tasks | New On Demand Backup Set.
  3. In the New Backup Set Name box, type a name (up to 32 characters).
  4. Click OK.
  Once an On Demand Backup Set has been created, it cannot be changed into a traditional backup set.

Creating User Defined Subclients

As file servers may contain large amounts of data, you can create user defined subclients to manage your backups, such as the following:

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP | Backup Set.
  2. Right-click the Backup Set and select All Tasks | New Subclient.
  3. In the Subclient Name box, type a name.
  4. Click the Storage Device tab.
  5. In the Storage Policy list, select a storage policy name.
  6. Click the Content tab.
  7. Select a root volume or file system from the Backup Content Path list and enter the path of the directory.
  8. Click Add.

    If the selected data is already included in any other subclient in the same backup set, it will be excluded automatically from that subclient. However, if it is included in any other backup set, it will not be excluded and will get backed up twice.

  9. Repeat steps 7 and 8 to include all the volumes, files, and directories to be backed up.
  10. Click Close.
  11. Click OK.

Use the following guidelines while specifying the content for a subclient:

BlueArc

You can include CIFS shares or NFS exports in the subclient content in the following format:

/__VOLUME__/<File System Name>/<path in the file system>

For example:

 /__VOLUME__/FS1/share1

 /__VOLUME__/FS1/share2

EMC Celerra/ Hitachi

Use the following format to define the subclient content:

/<File System Name>/<directory name>

For example:

/fs001/dir1

/fs001/dir2

NetApp

Use the following format to define the subclient content: the following format:

/<File System Name>/<directory name>

A maximum data size of 50-80G per subclient is recommended.

For example:

/vol/vol0

/vol/vol1

Configuring Multiple Streams for Backups

The Multi-Streaming feature enables multiple data streams per subclient for data protection operations. This allows backups of multiple paths in a subclient to run concurrently, as part of the same job, thus reducing the total number of running jobs. This feature is dependant on the number of available resources (drives) and can be useful in the following scenarios:

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP | Backup Set.
  2. Right-click the <Subclient> in the right pane and click Properties.
  3. In the Number of Data Readers box type or select the number of data streams.

    The actual number of concurrent backup streams employed during a backup job is limited by the number of resources available to the Storage Policy. The number of available resources will be limited if other subclients are also using the same Storage Policy or a specific content path requires more time for backup.

  4. Click the Storage Device tab.
  5. In the Storage Policy list, click a storage policy name.
  6. Click OK.
  The number of streams configured in the Storage Policy should be equal to, or greater than the specified Number of Data Readers.

Modifying User Accounts for a File Server

If the file server access information has been modified, follow the steps given below to change the user account settings.

  1. From the CommCell Browser, navigate to Client Computers | <Client>.
  2. Right-click the <File Server> NAS NDMP and click Properties.
  3. Click NDMP Properties.
  4. Select the Change Password check box.
  5. Enter the user name in the NDMP Login box.
    • For NetApp, type root.
    • For EMC Celerra, type ndmp.
    • For all other file servers, use any value.
  6. Enter the password in the NDMP Password box.
  7. Click OK.

Configuring Pre/Post Processing for Backups

You can add and modify Pre/Post processes for a subclient. These are batch files or shell scripts that you can run before or after certain job phases. For example, you can use an echo command to check the level of a backup. Similarly, you can include a case statement within a script to run specific operations based on the level of the backup job.

A Save As Script file can also be run as a pre/post process, if you include the absolute path of the associated input file in the script file.

Configuring a Subclient for Pre/Post Processing

The Pre/Post Process commands are executed on the MediaAgent associated with the active drive pool of the storage policy that is assigned to the subclient. Ensure that the required batch files or shell scripts are available on the MediaAgent where the Pre/Post commands are executed.

Follow the steps given below to specify the Pre/Post commands for a subclient:

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP | BackupSet.
  2. Right-click the <Subclient> in the right pane and then click Properties.
  3. Click the Pre/Post Process tab.
  4. Depending on the process you want to set up, enter the path of the batch file or the shell script in one of the following boxes:
    • PreBackup Process
    • PostBackup Process
  5. Click OK.

Setting Up Post Processes To Run During Failures

By default, a specified post process command is executed when a backup job is completed or killed.

Use the following steps to run a post process when the backup operation does not complete.

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP | BackupSet.
  2. Right-click the <Subclient> in the right pane, and then click Properties.
  3. Click the Pre/Post Process tab.
  4. Enter the path of the batch file or the shell script in the PostBackup Process box.
  5. Select the Run PostBackup Process for all attempts check box.
  6. Click OK.

Changing User Accounts for Executing Pre/Post Commands

For a Windows MediaAgent you must specify the user account and password required for executing the Pre/Post commands.

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP | BackupSet.
  2. Right-click the <Subclient> in the right pane, and then click Properties.
  3. Click the Pre/Post Process tab.
  4. Depending on the process you want to set up, enter the path of the batch file or the shell script in one of the following boxes:
    • PreBackup Process
    • PostBackup Process
  5. Click Change.
  6. Select one of the following user accounts:
    • Use Local System Account - Select this option to use the local system account on the MediaAgent for executing the Pre/Post Process commands. 
    • Impersonate User - Select this option to use an authenticated user account for executing Pre/Post commands. However, if the specified user account is not available on the MediaAgent, backup jobs using Pre/Post commands will fail.
  7. Click OK.

Configuring Filters for Backups

You can set filters to exclude certain files and directories from backups. Filters can also be used to exclude system-related files which consistently fail during a backup operation. See Content, Filters, and Regular Expressions for comprehensive information on filtering data from backup.

Follow the steps given below to configure filters for a subclient:

  1. From the CommCell Browser, navigate to Client Computers | <Client> | <File Server> NAS NDMP  | <Backup Set>.
  2. Right-click the <Subclient> in the right pane and then click Properties.
  3. Click the Filters tab.
  4. Under Exclude these files/folders/patterns, click Add.
  5. In the Enter Path box, type the paths or names of files and directories that you want to exclude.

    If you want to specify a file name pattern, you can use wildcards in the filter strings. The filter strings are case-sensitive.

    For example: If you want to filter all the filenames starting with LICENSE, specify LICENSE*. However, filenames starting with license (in lowercase) will not be filtered.

  6. Click OK.

You can modify or delete existing filter strings. Any modification to the filter configuration is effective during the following backup.

Use the following guidelines while entering the filters:

EMC Celerra
  • By default, you can specify a maximum of 5 directory and 5 file filters. The number of filters can be increased to 50 for each filter type by using the PAX.filter.numDirFilter or PAX.filter.numFileFilter parameters. Please consult the vendor documentation for information on configuring these parameters.
  • Filters are supported for DART OS 5.5 or higher.

Hitachi

 Filters are not supported.

NetApp
  • You can specify a maximum of 32 filters for a subclient.
  • Path filters are not supported.
  • When you specify a file or directory name and there are multiple files (and/or directories) with the same name in different locations, all of them will be excluded from the backup.
