Abstract:
An apparatus, system, and method are disclosed for restoring cluster server data at a volume level. A setup module opens at least one source volume of a cluster server for a volume-level restore, flushes each buffer for the at least one source volume, closes the at least one source volume, disables file system checks for the cluster disks, saves disk signatures of the cluster disks, and disables device-level checks for the cluster disks. A copy module copies data with a volume-level restore from the at least one snapshot volume to the at least one source volume. A reset module rewrites the saved disk signatures to the cluster disks, re-enables the device-level checks for the cluster disks, and resets at least one volume attribute on the at least one source volume.
