Hi,
The first point is to delete the restore points (Not the checkpoints)
Before you delete the Data Domain system from the VDP appliance, note the following:
- You must delete all restore points stored on the Data Domain by using the VDP plug-in on the vSphere web client.
And one VDP appliance can be connected to only one data domain. We cannot have VDP backing to multiple DD.
In this case, you would like to retain your backups until the old DD is discarded, so, what you can do is, setup a new VDP appliance (Should reside on an ESXi host which does not have an existing VDP appliance. 1 VDP per ESXi host; 10 per vCenter), and connect it to the new data domain and run the fresh backups.
