Abstract
Disaster recovery is provided for Software Defined Network Attached Storage where the data backup is implemented using asynchronous remote data replication. An asynchronous replication 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. During failover, all filesystems associated with the asynchronous remote data facility are failed over from a primary storage system associated with the primary storage array to a backup storage system associated with the backup storage array. Where an individual filesystem or individual VDM is to be failed over to the backup storage system, a separate asynchronous replication remote data facility is created to separately replicate data for the aspect to be individually failed over.
