Abstract
A first cluster node receives a request for a backup of files stored in a CSV shared with a second cluster node. A first VSS writer determines a first set of files associated with the first cluster node. A second VSS writer determines a second set of files associated with the second cluster node. A WMD file associated with the backup is generated to include a first component describing the first set of files and a second component describing the second set of files. A BCD file associated with the backup is modified to store information indicating the first VSS writer to restore the first and second sets of files, such that the first and second sets of files can be restored using the first VSS writer without having to use the second VSS writer. The backup is then performed to a backup storage device.
