The threshold setting will monitor the usage amount of snapshot space. When the
used snapshot space achieves its threshold, system will automatically take a clone
snapshot and start VD clone process. The purpose of threshold could prevent the
incremental copy fail immediately when running out of snapshot space.
For example, the default threshold is 50%. The system will check the snapshot space
every hour. When the snapshot space is used over 50%, the system will synchronize
the source VD and target VD automatically. Next time, when the rest snapshot space
has been used 50%, in other words, the total snapshot space has been used 75%,
the system will synchronize the source VD and target VD again.
Restart the task an hour later if failed: (The setting will be effective after
enabling schedule clone)
Figure 5.6.6
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.

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”.
