Managing snapshots

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

Adding snapshots to volume groups

To add snapshots to a volume group, use the Volumes > Volume Groups panel in management GUI. Select the volume group that needs to be associated with the snapshots and under the Snapshots tab, select Take Snapshot.

To add snapshots to a volume group using the command-line interface, see addsnapshot command.

Creating volume groups from snapshots

To create a volume group from snapshots, use the Volumes > Volume Groups > Create Volume Group panel in management GUI. Select Choose existing snapshot from a volume group, select the required snapshot and specify the copy type that is required.

To create a volume group from snapshots using the command-line interface, see mkvolumegroup command.

Restoring a volume group from snapshots

To restore a volume group from snapshots, use the Volumes > Volume Groups 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 Volumes > Volume Groups panel. To see when a volume group was last restored from a snapshot, go to the Properties option on the Volumes > Volume Groups panel. The commands lsvolumegroup and lsvolumegroupsnapshot show the equivalent data in the command-line interface.

To restore a volume group from snapshots using the command-line interface, see restorefromsnapshot command.

Deleting snapshots

To delete snapshots, use the Volumes > Volume Groups panel in management GUI. Select the volume group that needs to be associated with the snapshots and under the Snapshots tab, select the snapshot to delete and click overflow menu to select Delete.
