Refreshing the snapshot of volumes
When you refresh a snapshot of a volume, the snapshot volume is replaced with another point-in-time copy of the original volume.
When you refresh the snapshot of a volume, you can optionally create a space-optimized snapshot of the snapshot volume that you refresh. This action ensures proper data backup. The Management Server console lets you refresh the following types of volume snapshots:
-
Instant snapshots
-
Break-off mirror snapshots
You cannot perform this operation on a Windows host.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.
Note: Before refreshing a volume snapshot, you must unmount the file systems that are configured to use the selected volumes to prevent loss of data.
