Where should deduplication occur

This property specifies the deduplication action for clients if you use one of the following NetBackup deduplication options:

The following are the client direct options:

To always deduplicate the data on the media server, select Always use the media server (the default). Jobs fail if one of the following are true:
- The NetBackup Deduplication Engine on the deduplication storage server is inactive.
- The PureDisk storage pool is inactive.
To deduplicate data on the client and then send it directly to the storage server, select Prefer to use client-side deduplication. NetBackup first determines if the client direct library on the storage server is active. If it is active, the client deduplicates the backup data and sends it directly to the storage server, bypassing media server processing. If it is not active, the client sends the backup data to a deduplication media server. The deduplication media server deduplicates the data.
To always deduplicate the backup data on the client and then send it directly to the storage server, select Always use client-side deduplication. If a job fails, NetBackup does not retry the job.

You can override the Prefer to use client-side deduplication or Always use client-side deduplication host property in the backup policies.
