Veritas NetBackup™ Deduplication Guide

To specify the clients that deduplicate backups

1. In the NetBackup Administration Console, expand NetBackup Management > Host Properties > Master Servers.
2. In the details pane, select the master server.
3. On the Actions menu, select Properties.
4. Select the Client Attributes properties.

5. On the General tab of the Client Attributes properties, add the clients that you want to deduplicate their own data to the Clients list, as follows:

   • Click Add.

   • In the Add Client dialog box, enter a client name or browse to select a client. Then click Add.

     Repeat for each client that you want to add.

   • When you finish adding clients, click Close.

6. 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 deduplication 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.

   Note:

   NetBackup Client Direct deduplication is supported in a Cloud Catalyst duplication and also direct or primary backup to cloud scenario. Upgrade the load balancing media servers for a particular Cloud Catalyst server and the affected clients to NetBackup 8.2.1.
