I would like to modify the source objects of an existing Backup Copy job
Actualy the job Contain : VM1, VM2
I would like to replace it directy by the Job "Backup Job VM"
The "Backup Job VM" contain the same VM but only with DATA disk

In PowerShell i'm able to suppress VM1 and VM2 but i don't be able to add the backup job (in order to link the job)
It's very important for me to modify and not delete the existing job, because there are a lot of data already sent.
Thanks.
