Abstract:
Disaster recovery is provided for Software Defined Network Attached Storage where the data backup is implemented synchronous data replication. A synchronous replication remote data facility is created between a primary storage array and a backup storage array. User filesystems being handled by a virtual data mover (VDM) and a configuration filesystem describing the location of the user filesystems on the primary storage array are replicated on the remote data facility to the backup storage array. Individual filesystems, individual VDMs, or groups of VDMs may be selectively failed over from the primary storage array to the backup storage array.
