About MSDP client deduplication requirements and limitations
The clients that deduplicate their own data and the master server must use the same name to resolve the storage server. The name must be the host name under which the NetBackup Deduplication Engine credentials were created. If they do not use the same name, backups fail. In some environments, careful configuration may be required to ensure that the client and the master server use the same name for the storage server. Such environments include those that use VLAN tagging and those that use multi-homed hosts.
NetBackup does not support the following for client-side deduplication:
Multiple copies per job. For the jobs that specify multiple copies, the backup images are sent to the storage server and may be deduplicated there. Multiple copies are configured in a NetBackup backup policy.
NDMP hosts. The backup jobs fail if you try to use client-side deduplication for NDMP hosts.
For the systems on which NetBackup supports client-side deduplication, see the NetBackup compatibility lists at the following URL:

The clients that deduplicate their own data conform to the standard NetBackup release level compatibility. The NetBackup Release Notes for each release defines the compatibility between NetBackup releases. To take advantage of any new features, improvements, and fixes, Veritas recommends that the clients and the servers be at the same release and revision.
