About MSDP replication to a different domain

NetBackup supports replication to storage in a different domain. NetBackup Auto Image Replication is the method used to replicate backup images. (Backup image replication is not the same as snapshot replication, which may occur in the same domain.) You can replicate from one source to one or more destinations.

Table: NetBackup media server deduplication replication targets describes the MSDP replication source and targets that NetBackup supports.

Auto Image Replication does not support replicating from a storage unit group. That is, the source copy cannot be in a storage unit group.

If a replication job fails, NetBackup retries the replication until it succeeds or the source images expire. You can change the retry interval behavior.

See Configuring NetBackup optimized duplication or replication behavior.

If a job fails after it replicates some of the images, NetBackup does not run a separate image cleanup job for the partially replicated images. The next time the replication runs, that job cleans up the image fragments before it begins to replicate the images.

You can use a separate network for the duplication traffic.
