Advanced Configuration - NAS iDataAgent

Table of Contents

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. In the CommCell Browser, expand Client Computers | <Client>.
  2. Right-click NAS 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 NAS clients using the NetApp file server, 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 additional setting on the MediaAgent:

  1. In the CommCell Browser, expand Storage Resources | MediaAgents.
  2. Right-click the <MediaAgent> in which you want to add the additional setting, and then click Properties.
  3. Click the Additional Settings tab.
  4. Click Add.
  1. In the Name box, type OnDemandLocalFilePath.
  2. In the Category box, enter NAS.
  1. In the Type list, select STRING.
  2. In the Value field, type the full path of the content file.
  3. Click OK.
  4. Click OK to close the MediaAgent Properties dialog box.

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 NAS 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 often contain large amounts of data, you can create user defined subclients to manage your backups, such as the following:

  • To backup specific file systems or a portion of a file system.
  • If you want to back up different directories on a file server.

    For example, a file server has two directories that you want to back up. Create a user-defined subclient that consists of /fs1/dir1 and another user-defined subclient that consists of /fs1/dir2.

Procedure

  1. From the CommCell Browser, navigate to Client Computers | <Client> | NAS | <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.

    Note: For version 9 MediaAgents, the NDMP Remote Server add-on must be installed on the MediaAgent to select storage policies for all resources attached to the MediaAgent.

  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 (Hitachi NAS)

Use the following format to define the subclient content:

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

For example:

 /__VOLUME__/FS1/dir1

EMC Celerra/VNX/VNXe

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:

/<File System Name>/<directory name>

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:

  • A subclient contains multiple data paths.
  • A subclient is configured to back up the entire file server.

Note: For NetApp SnapProtect backups, multiple paths on the same volume can only use a single stream. Configuring multiple streams for NetApp SnapProtect backups is only useful when there are paths to multiple volumes in the subclient content.

  1. From the CommCell Browser, navigate to Client Computers | <Client> | NAS | <Backup Set>.
  2. Right-click the <Subclient> in the right pane and click Properties.
  3. Click the Advanced Options tab.
  4. 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.

  5. Click the Storage Device tab.
  6. In the Storage Policy list, click a storage policy name.
  7. Click OK.

The number of streams configured in the Storage Policy should be equal to, or greater than the specified Number of Data Readers.

Configuring Incremental Backup and Index to Use the Same MediaAgent

NAS incremental backup jobs must use the same MediaAgent to both run the backup job and create the index because those jobs must share the Job Results Directory. To ensure that the backup job and the index creation job use the same MediaAgent, you must configure a setting in the Control Panel.

To configure the incremental backup and index creation to use the same MediaAgent:

  1. Open the CommCell Console.
  2. On the Home ribbon, click Control Panel.
  3. Under Storage, click Media Management.

    The Media Management Configuration dialog box appears.

  4. Click the Resource Manager Configuration tab.
  5. Next to Force to use the same MediaAgent for create index and backup phase during NAS backup, click in the Value column, and then type 1.
  6. Click OK.

    This setting affects all new and future NAS incremental backup jobs. This setting does not affect currently running jobs.

Assigning a Subclient to a Billable Entity

You can assign a subclient to a particular billable entity in the Subclient Properties dialog box. This is useful if you want to assign subclients in the same Backup Set to different billing departments.

To assign a subclient to a billable entity:

  1. From the CommCell Browser, navigate to Client Computers | <Client> | NAS | <Backup Set>.
  2. Right-click the <Subclient> in the right pane and click Properties.
  3. Click the Advanced Options tab.
  4. From the Billable Entity list, select the name of a billable entity.
  5. Click OK to save your settings.

Modifying User Accounts for a File Server

The NAS iDataAgent requires a user account to access the file server to perform backup and restore operations. 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 NAS and click Properties.
  3. Click NDMP Properties.

    The NDMP Server Properties dialog box appears.

  4. Select the Change Password check box.
  5. Type 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. Type the password in the NDMP Password box.
  7. Click OK.
  8. Click OK to close the NAS Properties dialog box.

Configuring Pre and 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 and 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> | NAS | 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> | NAS | BackupSet.
  2. Right-click the <Subclient> in the right pane, and then click Properties.
  3. Click the Pre/Post Process tab.

    • 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.
  8. Click OK to close the Subclient Properties dialog box.

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.

Filter Guidelines

Use the following guidelines while entering the filters:

  • When a backup is performed on a subclient, any child paths from other subclients will be automatically filtered.

    For example, if a subclient backup contains /vol/myvol and another subclient has a content path /vol/myvol/dir1, then all files and directories named dir1 will be automatically filtered.

  • The following table contains vendor-specific filter guidelines:
    BlueArc (Hitachi NAS) You can specify an unlimited number of filters for each subclient.
    Dell Compellent FS

    Dell Equallogic FS

    Dell PowerVaultNX

    • You can specify a maximum of 32 filters for a subclient. Automatically added filters are counted toward the 32 filter limit.
    • Filters that include path information are not supported. Only directory names are supported as filters. For example, the filter the path /vol/myvol/dir1, you should add only dir1 as a filter.
    • Any file or folder that matches the filter name will be excluded. For example, if you have dir1 as a filter and there are multiple folders named dir1 in several different locations on the subclient, all of them will be excluded from the backup.
    EMC Celerra
    • EMC Celerra clients have two distinct filter types: directory filters (EMC_EDIR) and file filters (EMC_EFILE). Directory filters may contain path information to filter sub-directories, such as EMC_EDIR01=/dir1/subdir. File filters may only contain file names and extensions, such as EMC_EFILE01=filename.txt to filter all files named filename.txt, or EMC_EFILE02=*.mp3 to filter all MP3 files.
    • By default, you can specify a maximum of 5 directory filters 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.
    • Filters are not supported for volume-based backups (VBB). For information about volume-based backups (VBBs), see Volume Based Backup.
    EMC Isilon Filters are supported only for EMC Isilon filer version 6.5.4 and later.
    Hitachi Filters are not supported.
    NetApp
    • You can specify a maximum of 32 filters for a subclient. The 32 filter maximum includes any automatically added filters.
    • Path filters are not supported.

      For example, the path /vol/myvol/dir1 will either filter nothing or might filter all files and directories named dir1.

    • 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.

      For example, the filter dir1 will exclude all files and directories named dir1 from the backup.

    • The .snapshot directory is automatically filtered for NAS Agent backups.

Procedure

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

  1. From the CommCell Browser, navigate to Client Computers | <Client> | NAS  | <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.

Configuring Libraries and Drives Attached to a File Server

Auto-detection is the recommended method of configuring library and drives attached to a file server. The auto-detection method is explained in Getting Started.

The settings of the file server determine how the file server connects to the MediaAgent. If you want to define the interface used to connect the MediaAgent to the file server, you can use the Data-Interface-Pairs (DIP) feature from the CommCell console. To define a connection between the MediaAgent and the file server from the CommCell console, refer to the Data-Interface-Pairs documentation for instructions.

Configuring a Library Shared across a SAN Environment

In a SAN environment, the drives in a library can be dynamically shared between the file servers and MediaAgents. When you share a library between two file servers, the file server configured first will control the media changer. The same rule applies for a library shared between a MediaAgent(s) and file server(s).

  1. Configure the shared library using a file server. For more information refer to Configure Libraries and Drives Attached to a NAS Storage Server Using Automatic Detection.
  2. On the Storage tab, click Library and Drive.

    The Libraries tab provides the physical view of the devices (library and drives).

Additional NAS Features

Configuring a Subclient for Tape Silvering

Feature Description Applies To
Tape Silvering Tape silvering is the process of shipping a physical copy of the source data to a destination site. This is useful for large file systems as it saves time and resources and also avoids transferring the file system over the network. Refer to the EMC Celerra documentation for more information. EMC Celerra running version 5.6 or higher.
  1. From the CommCell Browser, navigate to Client Computers | <Client> | NAS  | Backup Set.
  2. Right-click the Subclient in the right pane and then click Properties.
  3. Click the Content tab.
  4. Under Backup Content Path, specify the source path of the replication that was created from the Celerra Management Console or command line. Append .ts to the path name. For example, /sourcefs/.ts.
  5. Click Add.
  6. Click OK.

Configuring Image Backups (SnapMirror to Tape)

Feature Description Applies To
SnapMirror To Tape Image backup allows you to perform a snapshot backup of an entire volume to media. Restoring from an image backup provides faster volume recovery than a file based restore.

You can change the configuration of a backup set at any time to perform either regular backups or image backups. The configuration change takes effect when the next Full backup runs.

For full backups, when moving a snapshot to tape, or if a snapshot name is set in the Snapshot to Backup option, then the snapshot and all previous snapshots are included in the full backup. If these options are not selected, then all of the used blocks on the volume, including the snapshots and .snapshot folder data, are included in the full backup.

For incremental backups, when moving a snapshot to tape, or if the Snapshots to Back-up option is enabled, then only blocks that have changed, including snapshots, with respect to the previous backup are included in the incremental backup.

Consider the following before configuring image backups:

  • It is not possible to perform file level restores from an image backup. Only entire volumes can be restored from image backups.
  • Deduplication rates might be low for image backups that are enabled with SnapMirror to Tape.
  • Incremental and differential backups are supported on image backup sets with file servers running ONTAP 8.1.1 or higher. If you have an ONTAP version lower than 8.1.1, then only full backups are supported. 
  • To perform an incremental or differential backup, you must have configured the Snapshot to Backup option or the backup must be moving a snapshot to tape. Also, the previous full backup must have had the Snapshot to Backup option configured or moved a snapshot to tape. For instructions, see Incremental Backups for SnapMirror to Tape.

Follow the steps below to create a backup set for image backups:

  1. From the CommCell Browser, navigate to Client Computers | <Client>.

    Click No to cancel the deletion and retain the subclient, or click Yes to continue the deletion.

Configuring a MediaAgent to Interface with File Servers

By default, information about new NAS clients (file servers) is collected using the CommServe software to interface with the file servers. If the CommServe computer does not have direct access to the file servers, such as when the CommServe software is hosted in the cloud or at a service provider, you can configure the MediaAgent to access file servers instead of the CommServe computer.

Before You Begin

To complete this procedure, you will need the following information:

  • The host name of each file server that you want to configure using a MediaAgent.
  • The host name of the MediaAgent(s) you want to use to configure the file server(s).

About this Task

To use a MediaAgent to interface with file servers instead of the CommServe computer, you must create an additional setting on the CommServe computer. You can use this additional setting to either:

  • Use a MediaAgent to interface with all new NAS clients by default.
  • Specify a MediaAgent that you want to interface with a particular file server.

    If you are using this additional setting to specify a MediaAgent you want to use to interface with a particular file server, you can create a new additional setting for each file server.

Procedure

  1. Open the Additional Settings tab for the CommServe computer. See Add or Modify an Additional Setting.
  2. In the Name box, proceed as follows:
    • To use a MediaAgent to interface with all new file servers by default, type sNasFileServerMA.
    • To specify a MediaAgent to interface with a particular file server, type sNasFileServerMA_<file_server_name>.

      file_server_name is the host name of the file server that you want to add as a NAS client using a MediaAgent.

      For example, if the host name of the file server is FileServer_01, enter sNasFileServerMA_FileServer_01.

  3. In the Category box, type NAS.
  4. In the Type box, type STRING.
  5. In the Value box, type the host name of the MediaAgent that you want to use.
  6. Verify that the Enable check box is selected and then click OK.

After this configuration, information about new NAS clients will be collected from the file servers using the specified MediaAgent.

Configuring a ZFS File Server

To perform backup and restores for a ZFS file server, the following configurations are required:

  1. Add the following Additional Setting on the CommServe client (see Add or Modify an Additional Setting):
    • Name: sAllowZFS
    • Category: NAS
    • Type: STRING
    • Value: Y
  2. In the CommCell Browser, click the NAS client name, right-click the NAS icon under the client, and then click Properties.
  3. Click NDMP Properties.
  4. Click Detect and then click OK.
  5. Define subclient contents as canonical paths. See Creating User Defined Subclients.

For instructions on performing a backup for a ZFS file server, see Backup a ZFS File Server.

Configuring a Firewall Between a File Server and MediaAgent

When the file server and MediaAgent are separated by a firewall, you can use the following procedure to define the ports for transferring data between the two machines.

Before You Begin

Ensure the port for the NDMP control connection is open in the firewall. The port for NDMP control connection is set when adding a NAS client. Typically, port 10000 is used for the NDMP control connection.

To view or change the port used for NDMP control connection of a NAS client:

  1. In the CommCell Browser click to expand the NAS client, right-click the NAS agent, and then click Properties.
  2. Click NDMP Properties.
  3. Change the value of Listen Port and then click OK.

Procedure

  1. In the CommCell Browser, expand Storage Resources > MediaAgents.
  2. Right-click the MediaAgent associated to the storage policy used for backups of the file server and then click Properties.
  3. Click Firewall Configuration > Incoming Ports.
  4. In the From and To boxes, click to select the range of port numbers that you want to allow and then click Add.

    The specified port ranges appear in the Additional Open Ports box.

  5. To specify more ports, select a new range of port numbers and then click Add.
  6. When you are finished adding ports, click OK.
  7. In the CommCell Browser, right-click the same MediaAgent, point to All Tasks, and then click Push Firewall Configuration.

The specified ports are pushed to the MediaAgent and used to transfer data between the MediaAgent and file server.

Adding a CIFS or NFS Network Share Backup to a NAS Client

You can add a CIFS or NFS network share to a NAS client by adding an existing Windows File System Agent or UNIX File System Agent to the NAS client.

Before You Begin

You must have a Windows or UNIX client configured in your CommCell console.

Procedure

  1. From the CommCell Browser, expand Client Computers.
  2. Right-click the NAS client you want to configure, point to All Tasks and click Add Network Share Backup.
  3. In the Add Network Share Backup dialog box, select the operating system of the client you want to add.
  4. Click Primary Client, select the client you want to add, and click OK.

    The selected file system agent appears under the NAS client in the CommCell Console.

  5. In the file system agent under the NAS client, create a new subclient and add the path to the CIFS or NFS network share to the subclient content. See Creating User Defined Subclients.
