Taking a Snapshot
After reserved space is set, you can proceed to take snapshots. To create a snapshot, follow
these steps:
1.
Go to "Storage Manager" > "STORAGE" > "Storage Space".
2.
Select a volume or LUN and click "Snapshot" > "Take a Snapshot".
3.
Specify the snapshot name and duration to retain the snapshot.
4.
Click "OK".
Managing Snapshots with Snapshot Manager
The Snapshot Manager allows you to take, revert, delete, and clone a snapshot, set up
snapshot schedules, or restore snapshot files.
To launch Snapshot Manager, select a volume or LUN in "Storage Space" and click
"Snapshot" > "Snapshot Manager" (or click the camera icon of a volume or LUN.)
In Snapshot Manager, you can perform the following actions:

Restore files: Click a desired snapshot and select the folder(s) or file(s) that you want to
restore, right click and select "Restore" to replace the existing folder/file with the one in
the snapshot or "Restore to" to restore your data to a different location. Or choose
"Download" to download the selection to your computer.

Revert a snapshot: Select a snapshot and click "Revert", and the entire snapshot will be
restored to its original path. Be cautious that the volume reverted to the selected
snapshot will be in the previous state when the snapshot was taken.

Delete: Select a snapshot and click "Delete" to delete that snapshot.
