The user can use VD clone function to backup data from source VD to target VD, set up
backup schedule, and deploy the clone rules.
The procedures of VD clone are on the following:
1. Copy all data from source VD to target VD at the beginning (full copy).
2. Use Snapshot technology to perform the incremental copy afterwards. Please be fully
aware that the incremental copy needs to use snapshot to compare the data difference.
Therefore, the enough snapshot space for VD clone is very important.
