5.6 VD clone
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 iSnap 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.
The following contents will take an example of a RAID 5 virtual disk
(SourceVD_Raid5) clone to RAID 6 virtual disk (TargetVD_Raid6).
