About NetBackup for SharePoint Server and client-side deduplication

When you use the NetBackup for SharePoint Server with client-side deduplication, the job details only show that deduplication occurs on the front-end Web server. The job is reported this way even if client-side deduplication is enabled for the SQL client and the other SharePoint farm hosts. Deduplication is performed if you choose Prefer to use client-side deduplication or Always use client-side deduplication.

The bpbrm logs contain information on the deduplication process (shown as "Client Direct"). For example, the log for a SQL Server back-end server is as follows:

15:49:13.947 [4892.8600] <2> bpbrm main: bpbrm.c.2767: Client Direct is using 
alternate client: FABLE
15:49:13.947 [4892.8600] <2> initiate_proxy_server: Calling bpcr_start_proxy 
with hostname:FABLE
