Managing snapshots
You can use the management GUI or the command-line interface (CLI) to manage snapshots, safeguarded snapshots, and the volume groups.

Creating volume groups from snapshots

Restoring a volume group from snapshots
To restore a volume group from snapshots, use the panel in management GUI. Select the volume group that needs to be associated with the snapshots and under the Snapshots tab, select the Restore option on the overflow menu for the snapshot being used for the restore. There is an option to either restore the entire volume group or a subset of volumes within that group. Select the applicable option and the subset of volumes if applicable and select Restore.
In the management GUI, to see when a snapshot was last used for a restore, go to the Snapshots tab on the panel. To see when a volume group was last restored from a snapshot, go to the Properties option on the panel. The commands lsvolumegroup and lsvolumegroupsnapshot show the equivalent data in the command-line interface.
