D-Link DSN-6020 User Manual page 98

Restart the task an hour later if failed: (The setting will be effective after

enabling schedule clone)
When running out of snapshot space, the VD clone process will be stopped because
there is no more available snapshot space. If this option has been checked, system
will clear the snapshots of clone in order to release snapshot space automatically, and
the VD clone will restart the task after an hour. This task will start a full copy.
Caution
The default snapshot space allocated by the IP SAN storage is two times
the size of source virtual disk. That is the best value of D-LINK's
suggestion. If user sets snapshot space by manually and lower than the
default value, user should take the risk if the snapshot space is not enough
and VD clone job will fail.
5. After deploying the VD clone rule, the VD clone process can be started now. Firstly,
Click "Set clone" to set the target VD at the VD name "SourceVD_R5".
Select the target VD. Then click "Confirm".
