Using Multiple Streams to Restore Data with the Windows File System Agent

By default, restore operation uses a single stream. For faster restore operations, you can configure the restore operation to use multiple streams, and you can define alternate data paths. For more information, see GridStor® (Alternate Data Paths) - Overview.


  • You cannot use multiple streams for restore operations on clients with only File System Core package installed (Laptop Backup clients).
  • You cannot use multiple streams for restoring systems state backups.

Before You Begin

  • Verify that you have v11 Service Pack 6 or later installed on the source client computers and on the destination client computers.
  • Verify that the client computer whose data you want to restore was backed up using Indexing Version 2. For more information about Indexing Version 2, see Indexing Version 2: Overview.
  • For more information about general restore options, see Restore/Recover Options (General).
  • For more information about the Advanced Options, see Advanced Restore Options.


  1. From the CommCell Console, expand Client Computers > client > File System > backup set.
  2. In the right pane, right-click a subclient, and then click Browse and Restore.

    The Browse and Restore Options dialog box appears.

  3. Click View Content.
  4. Select the data that you want to restore, and then click Recover All Selected.

    The Restore Options dialog box appears.

  5. On the General tab, complete the following steps:
    1. From the Destination Client list, select the destination client computer.
    2. In the Number of Streams box, enter the recommended number of data streams that you want to use for the restore operation.


      • The actual number of streams used depends on the restore data set and the number of streams used to back up data.
      • When you perform a restore by jobs operation, the Number of Streams option is not available because restore by job operations use multiple streams by default.
  6. On the Job Initiation tab, choose how you want to initiate the restore jobs.

    For more information about job initiation options, see Restore Options (Job Initiation).

  7. Click OK.


The restore operation restores the selected data to the destination client computer.
