IDSunit can be transformed in sync-center, replication of several IDSbox. Thanks to their high stockage capacity, they can be used as a central storage to get replicated data of several distant sites.
Each distant IDSbox is then considered as an account (one licence). Each account has its own synchronization programs, the same way it would be a true physical IDSbox.
With USB ports, the backup and replication administrator can rebuild on demand all the content of a distant IDSbox volume.
