Apparatus, system, and method for volume-level restoration of cluster server data

A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

• open at least one source volume of a cluster server for a volume-level restore;
• flush each buffer for the at least one source volume;
• close the at least one source volume;
• disable file system checks for cluster disks associated with the at least one source volume;
• save disk signatures of the cluster disks;
• disable device-level checks for the cluster disks;
• copy data with a volume-level restore from at least one snapshot volume to the at least one source volume;
• rewrite the saved disk signatures to the cluster disks;
• re-enable the device-level checks for the cluster disks;
• and
• reset at least one volume attribute on the at least one source volume.

A system to restore cluster server data at a volume level, the system comprising:

• a plurality of cluster servers;
• cluster disks comprising at least one source volume configured to store data for the plurality of cluster servers;
• snapshot disks comprising at least one snapshot volume configured to store a backup instance of the at least one source volume;
• a computer comprising
• a setup module configured to open the at least one source volume for a volume-level restore, flush each buffer for the at least one source volume, close the at least one source volume, disable file system checks for the cluster disks, save disk signatures of the cluster disks, and disable device-level checks for the cluster disks;
• a copy module configured to copy data with a volume-level restore from the at least one snapshot volume to the at least one source volume;
• and
• a reset module configured to rewrite the saved disk signatures to the cluster disks, re-enable the device-level checks for the cluster disks, and reset at least one volume attribute on the at least one source volume.

A method for deploying computer infrastructure, comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of performing the following:

• preparing an application for recovery;
• directing the application to quiesce a data set of at least one source volume
• opening the at least one source volume of a cluster server for a volume level restore;
• flushing each buffer for the at least one source volume;
• closing the at least one source volume;
• disabling file system checks for cluster disks associated with the at least one source volume;
• saving disk signatures of the cluster disks;
• disabling device-level checks for the cluster disks;
• copying data with a volume-level restore from at least one snapshot volume to the at least one source volume;
• rewriting the saved disk signatures to the cluster disks;
• re-enabling the device-level checks for the cluster disks;
• resetting at least one volume attribute on the at least one source volume;
• unmounting the at least one source volume;
• mounting the at least one source volume;
• re-enabling the file system checks for the cluster disks;
• and
• directing the application to run a recovery operation
