About client-side deduplication

Client-side deduplication enables a remote computer to send data directly to an OpenStorage device or a deduplication disk storage device. By using client-side deduplication, the Backup Exec server is bypassed, which leaves the Backup Exec 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 disk storage device or an OpenStorage device. Client-side deduplication is available for Windows computers and Linux computers.

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 Agent for Windows is required on the remote Windows computer to perform Windows client-side deduplication. The Agent for Linux is required on the Linux computer to perform Linux client-side deduplication.

  • The remote computer must be pingable.

  • The remote computer cannot be a Backup Exec server.

  • A deduplication disk storage device or an OpenStorage device must be used for the backup job.

  • The option Client-side deduplication must be enabled on the properties for the storage device.

  • The option Enable the remote computer to directly access the storage device and to perform client-side deduplication, if it is supported must be selected in the Storage options for the backup job. This option is selected by default when you select a deduplication disk storage device or an OpenStorage device as the storage for a backup job.

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