Changed Vm object in backup job

[chriskarako]

Hello all
I have an incremental job for one windows 2012R2 vm with two disks (os, and data) and 48 restore points configured.
Now we are in the 12th restore point
Recently we replaced this vm with one windows 2016 vm (different vm name) but with the same data disk.
How can we manage to "insert " this vm into the backup chain in the same scheduled job , without creating a full backup of the data disk ?
Thanks in advanced !!

Hi Chris - a Veeam Backup & Replication job can have multiple items in it - VMs, Datastores, vSphere Tags, vApps, Folders, etc. With the backup job having the one VM in it - if we simply add the new VM with a different name (not sure if you need to remove the old one or not, but you can) and the job will carry on. What will happen however is worst case a "snap and scan" - it will start looking and indicate that this is data already in the backup and not be a full transfer again. I expect there would be reads of the data disk, but no heavy writes to the backup repository.

Meaning... you will not have a new full backup. I think that's what you are asking

it will start looking and indicate that this is data already in the backup and not be a full transfer again.

This is valid in case the job is reverse incremental, since the blocks of the new VM will fall into the same full backup file and will be deduped. In case of forward incremental, where a new incremental backup file is created, the entire new VM data will fall there, since technically this is a different VM (having a different VM ID).
