Create your Snapshoot in Volume Manager.
Assign the Snapshot to the Logical Volume
Create Snapshot share then create share and place in Snapshot share (if Read only set in nas resources"SMB function").
• Create a new share that will be assigned to previous activated snapshot,
• Go to menu CONFIGURATION -> NAS resources, In function Create new share:, enter share name,
• Use option Specified path and select snapshot that you want to have access to,
• Click on apply button to create a share.
• Now you can start to explore your share (snapshot) using specified network
protocol.

Then create your Snapshot task for your times and day settings.
Location MAINTENANCE -> snapshot -> Snapshots -> [snapshot_name] -> Function:

Note
Please be reasonable, when you are calculating the space reserved for snapshots. Please set as snapshot size as much space as you expect to change during active snapshot. E.g. when you are doing backup from snapshot which takes one hour please set this snapshot size to as much space that will be changed during one hour. The snapshot will become inactive if the content (data changed on Logical Volume) exceeds the snapshot capacity. You do not lose data in that case, just the dataset, which is virtual for the users at the moment, will be written to the data volume. The old dataset, which has been frozen with the snapshot, is not available any longer.
When you define the schedule, use only as many snapshots in the same time as really needed. A large count of active snapshots can slow down the system considerably.
Manual creating and removing of snapshots can be done in the CONFIGURATION -> volume manager -> vg[nr] -> Function: Volume Manager.
