Restoring files from Snapshot copies

You can use a Snapshot copy to recover individual files or LUNs, or to restore the entire contents of a volume. You can restore files from an NFS or CIFS client as well as from the storage system. This feature requires a SnapRestore license, which is included in the Fundamentals Bundle.

  • Restoring a file from a Snapshot copy on an NFS or CIFS client
    A user on an NFS or CIFS client can restore a file directly from a Snapshot copy without the intervention of a storage system administrator.
  • Restoring a single file from a Snapshot copy
    You can use the volume snapshot restore-file command to restore a single file or LUN from a Snapshot copy. You can restore the file to a different location in the parent read-write volume if you do not want to replace an existing file.
  • Restoring part of a file from a Snapshot copy
    You can use the volume snapshot partial-restore-file command to restore a range of data from a Snapshot copy to a LUN or to an NFS or CIFS container file, assuming you know the starting byte offset of the data and the byte count. You might use this command to restore one of the databases on a host that stores multiple databases in the same LUN.
  • Restoring the contents of a volume from a Snapshot copy
    You can use the volume snapshot restore command to restore the contents of a volume from a Snapshot copy.
