About client-side deduplication

Client-side deduplication enables a remote computer that is configured as a Remote Agent for deduplication to send data directly to an OpenStorage device or a deduplication storage folder. By using client-side deduplication, the media server is bypassed, which leaves the media server free to perform other operations. If your deduplication device supports client-side deduplication, a remote computer deduplicates data and then sends only the unique data directly to a deduplication storage folder or an OpenStorage device.

Note:

Client-side deduplication may increase the CPU utilization on the remote computer if your deduplication device supports client-side deduplication.

When you create a backup job with client-side deduplication, keep in mind the following items:

  • The backup job can include resources from only one remote computer.

  • The Remote Agent for Windows Systems must be installed and running on the remote computer.

  • The remote computer must be configured as a Remote Agent for Deduplication.

  • The remote computer must be pingable.

  • The remote computer cannot be a Backup Exec media server.

  • A deduplication storage folder or an OpenStorage device must be selected in the Device and Media view for the backup job.

  • The option Use client-side deduplication must be selected in the Device and Media view for the backup job. This option is selected by default when you select a deduplication storage folder or an OpenStorage device as the destination for a backup job.

  • The Backup Exec service account enables remote computers to directly access a Symantec PureDisk device. If you want to perform backups that are enabled for Granular Recovery Technology, the Backup Exec service account must be valid for any remote computer that directly accesses the Symantec PureDisk device. You must verify that the remote computers are in the same domain, or that the remote computers have a domain trust relationship with the domain in which the media server resides.

If you do not configure the remote computer to use client-side deduplication, then the data from the remote computer is sent to the media server to be deduplicated. Then, the deduplicated data is backed up to the deduplication storage folder or the OpenStorage device. This process increases the CPU utilization on the media server. However, this process is useful if you are backing up older remote computers.
