Performing Document Level Backups and Restores › Document Level Backup › Multistream Option

Multistream Option

If your Arcserve Backup server is equipped with multiple devices in two or more groups or multiple devices in one or more groups with the Arcserve Backup Enterprise Module and Arcserve Backup Tape Library Option installed, you can take advantage of the Multistream option. This option divides your backup jobs into several sub-jobs that run simultaneously to different devices. You can have as many jobs running simultaneously as you have devices or groups on your system. Document Level backup provides one to five streams for simultaneous backup. The available number of tapes, drives, and storage groups determines the number of streams that are run simultaneously during backup.

Note: You can enable the Multistream option on the Destination tab in the Backup Manager.

For more information on the Multistream option, see the Administration Guide.

Note: If you enable the Multistream option when you submit a Document Level backup job, the data is multistreamed at the storage group level for Microsoft Exchange Server 2003, or 2007. For example, if your Exchange Server has two storage groups and you enable the Multistream option during backup, one subordinate job is created for each storage group. For Exchange Server 2010, the number of streams is determined by the database.
