Creating a Subclient for NFS Exports

Applies To: Content paths that include the mount point

You can add content to the default subclient or to additional subclients. You can browse for content or you can manually add content.

If the content of subclients overlap, then the backup of each share is done individually.

You can configure data access nodes as backup nodes for the network share subclient. The backup operation runs on the selected nodes. You can set data access nodes at the agent level or at the subclient level. The nodes set at the subclient level take precedence.

Before You Begin

Review the considerations for the mount point format.
Mount the NFS export from the file server in the same directory on all the Linux data access nodes.

For example, to mount a volume named vol_abc from a file server at 172.19.77.5 to a mount point named /test, the command would be:
```
mount 172.19.75.75:/vol/vol_abc /test
```

Procedure

From the CommCell Browser, expand Client Computers > client > Linux File System.
Right-click the backup set, point to All Tasks, and then click New Subclient.

The Subclient Properties dialog box appears.
In the Subclient Name box, type a name for the new subclient.
On the Content tab, add the paths to the content you want to back up:

Note

For Dell EMC Isilon/PowerScale NFS Exports, NFS Alias is not supported. However, you can use an Export path.
- To view the available mount paths, click Browse, and then select the mount path where the NFS export is mounted on all the data access nodes as content for backup.
  
  The content from the first data access node selected on the Backup Nodes tab at the agent level is displayed.
- To manually add a path, click Add Paths, and then type the mount path where the NFS export is mounted on all the data access nodes.
  
  Wildcards are supported in the subclient content path. For information about supported wildcards, see Wildcards for the UNIX/Linux File System Agent.
On the Storage Device tab, in the Storage Policy list, click a storage policy name to associate with the subclient.

Tip

To create a new storage policy, click Create Storage Policy and follow the instructions in the storage policy creation wizard.
On the Data Access Nodes tab, under Available Data Access Nodes, select the data access nodes that will participate in the backup operation, and then click Add.
Note
- You can select a client or a client group (containing Linux clients) from the available nodes list.
- All of the participating backup nodes must be at the same service pack level.
On the Performance tab, select the Allow multiple readers within a drive or mount point check box, and then increase the number of data readers as needed based on the number of data access nodes added.
On the Advanced Options tab, select the Reconcile Backup check box.
Click OK.
