Unitrends offers disaster recovery with both on-premise archiving and off-premise replication.
Choosing which to use will be based on your particular needs, but the most effective disaster recovery strategy will be one in which these choices have been made well in advance.
Archiving is accomplished by storing backups on removable media, while replication involves block-level deduplication of backups to an off-site location (also referred to as the disaster recovery site) in which a replication target system has been configured. Replication may be used alone for disaster recovery or in conjunction with archiving.
Note: Disaster recovery from tape archive is not supported.
Successful recovery from a disaster using the Unitrends solution requires that replication and/or archiving has been previously configured and implemented.
A Unitrends system’s metadata (its system state) is automatically backed up when archiving or replicating. This metadata holds information such as clients added to the system, client schedules, storage configuration, and system settings. Restoring this metadata rebuilds a Unitrends system in the event of a disaster.
Warning! A system automatically protects itself by sending metadata to archive media or a replication target each time you archive or replicate backups. You should never manually back up a Unitrends system itself.
