Configuring Live Browse on AIX and Linux

If metadata collection was disabled during backup, a live browse is initiated by mounting the snapshot on a proxy (pseudomount) and the backed up extents are recalled on demand.

By default, snapshots are mounted on the source client. You can select any other compatible client from the CommCell Console.

Live browse requires a staging folder to store the extents and metadata. The size of the staging folder can be as large as the restore data. If the size of the staging folder is smaller than the restore data, then the extents are pruned based on the LRU (Least Recently Used) algorithm, for the new extent restores. This might result in decreased performance during the restore operation.

On Linux, configure the staging folder on the "X" File System (XFS). By default, the staging folder is in the job results directory. You can configure a different path to the staging folder by using the sPseudoMountStagingFolder additional setting.


  1. From the CommCell Console, expand Client Computers.
  2. Right-click the Client, and then click Properties.
  3. In the Client Computer Properties dialog box, click Advanced.
  4. In the Advanced Client Properties dialog box, on the Additional Settings tab, click Add.
  5. In the Add Additional Settings on Unix Client dialog box, specify the path to the staging folder:
    1. In the Name box, type sPseudoMountStagingFolder. The Category and Type details are automatically populated.

      Click Lookup and search for the additional setting using the Find box.

    2. In the Value box, type the path to the staging folder.

      For example: /pseudomountCache

    3. Click OK.
  6. Click OK to close the Advanced Client Properties dialog box and the Client Computer Properties dialog box.
