I had to recreate a VM in Hyper-V (create a new one with blank disks and then attach the old disks). However now, when trying to backup the VM I get 'object was not found' and the VM fails.
I've read through the forums, and tried removing the VM from the job - re-scanning the Hyper-V host (actually I re-scanned them all), and then re-adding the VM to the job. But I still get the same error.
If I try to re-calculate the job, it works fine, and reports the size of the VM correctly.
Any further ideas or things to try here ?
