To enable Client Deduplication, set an attribute in the NetBackup master server Client Attributes host properties.
To specify the clients that deduplicate backups
In the NetBackup Administration Console, expand NetBackup Management > Host Properties > Master Servers.
On the Host Properties General tab, add the clients that use client direct to the Clients list.
Select one of the following Deduplication Location options:
Always use the media server disables client deduplication. By default, all clients are configured with the Always use the media server option.
Prefer to use client-side deduplication uses client deduplication if the PureDisk plug-in is active on the client. If it is not active, a normal backup occurs; client deduplication does not occur.
Always use client-side deduplication uses client deduplication. If the deduplication backup job fails, NetBackup retries the job.
You can override the Prefer to use client-side deduplication or Always use client-side deduplication host property in the backup policies.
