4.6 VD Clone
The user could use VD clone 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. Fully copy data from source VD to target VD at the beginning.
2. Using 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.
The following contents will take an example of a RAID 5 virtual disk (SourceVD_Raid5)
clone to RAID 6 virtual disk (TargetVD_Raid6).
Start VD clone
1. Create RAID group (RG) in advance.
2. Create SourceVD_Raid5 and TargetVD_Raid6. The raid type of backup target need
to be set as “BACKUP”.
