About OpenStorage storage servers for backups

A storage server is an entity that writes data to and reads data from the storage. It may correspond to a physical appliance or disk array. It may be a higher level construct such as a host-based management software suite for multiple devices. The storage server owns exclusive access to the storage.

For the OpenStorage solutions that use a disk appliance for backups, the disk appliance host is the storage server.

How many storage servers you configure depends on your backup storage requirements. Each disk appliance has one storage server. If you use optimized duplication or replication, additional storage servers are required, as follows:

Optimized duplication within the same NetBackup domain

Optimized duplication in the same domain requires the following storage servers:

One for the backup storage, which is the source for the duplication operations.
Another to store the copies of the backup images. This storage server hosts the storage that is the target for the duplication operations.

See About OpenStorage optimized duplication within the same domain.

Auto Image Replication to a different NetBackup domain

Auto Image Replication requires the following storage servers:

One for the backups in the originating domain. This storage server writes the NetBackup client backups to the storage. It is the source for the duplication operations.
Another in the remote domain for the copies of the backup images. This storage server is the target for the duplication operations that run in the originating domain.
