System image recovery to Hyper-V VM using differencing disks
Posted on 2014-01-07
I have a lot of large VMs using fixed size disks that I'd like to restore onto a child VM that uses a differencing disk, the parent of which uses the same OS as the VM I'm trying to restore. Unfortunately because the disks are different I get a 0x80042412 error when trying a system image recovery restore.
Is there any way to use Windows system image recovery or something similar to restore a backup of the large VM into one that uses differencing disks and which should store the same data much more efficiently?
