In certain situations, you need to revert a volume to a selected Snapshot copy using SnapRestore. You should notify the users of the volume before you revert that volume.
|You know the name of the Snapshot copy for each volume you want to revert||Go to Step 5.|
|You want to choose a Snapshot copy from the list of Snapshot copies available for reversion||Go to Step 2.|
vol_name is the name of the volume to be reverted. Enter the name only, not the complete path. You can enter only one volume name.
Use the -f option to avoid warning messages and prompts to confirm your decision to revert the volume. For more information, see the na_snap(1) man page.
-s snapshot_name specifies the name of the Snapshot copy from which to revert the data. You can enter only one Snapshot copy name.
|You want to continue with the reversion||Press y.
Result: The system reverts the volume from the selected Snapshot copy. If you are reverting the root volume, the system reboots.
|You do not want to proceed with the reversion||Press n or Ctrl-C.
Result: The volume is not reverted and you are returned to a prompt.
system> snap restore -t vol -s nightly.0 /vol/vol1 system> WARNING! This will restore a volume from a snapshot into the active file system. If the volume already exists in the active file system, it will be overwritten with the contents from the snapshot. Are you sure you want to do this? y You have selected file /vol/vol1, snapshot nightly.0 Proceed with restore? y
Result: Data ONTAP restores the volume called vol1 at /vol/vol1.
After a volume is reverted with SnapRestore, all user-visible information (data and attributes) for that volume in the active file system is identical to that contained in the Snapshot copy.
