Start by identifying the Managed Object Reference-ID (MORef-ID) of the VM.
If the VM is being protected by Veeam Backup & Replication, navigate to the log directory on the Veeam Server (%programdata%\Veeam\Backup). Within that directory, find the folder that is named after the job that the VM is protected by. Within the job folder will be a log named Task.<vmname>.<Ref-ID>.log
If the Ref-ID starts with “vm-“ the job is connecting to the vCenter server.
If the Ref-ID is just a number, the job is connecting to a standalone host.
- Now using an web browser navigate to: https://<vc/host ip>/mob/?moid=<Ref-ID>
Example for VC: https://abp-vc.abp.lab/mob/?moid=vm-688
Example for host: https://esxi1.abp.lab/mob/?moid=26
- Create a snapshot for the virtual machine, and note that snapshot ref-id on the MOB page.
- On the MOB page for the VM click "QueryChangedDiskAreas"
- Insert the following parameters:
snapshot reference id
device key of a virtual disk
start offset (the beginning of the required changed area)
change id (use "*"(star symbol) to query all used space)
- Click "Invoke Method" and then result will be shown at the bottom in the same window.
The table contains changed disk areas start offsets and lengths.
