Guest files restore: GPT error

Post by corona_backup » Mar 26, 2020 11:53 pm

Case-ID# 04075929
Additional Details: Environment: hyper-v (srv 2019 std., patchlevel up2date)
Veeam: B&R (community edt.)

I tried to restore some files from a Windows Guest backup. FLR window started an immediately got me this error:

Invalid GPT Partition entry array checksum: 0123456789 (calculated: 9876543210) Agent failed to process method {Mount.GenericMount}.

A checkdsk on the running guest as well on the hyper-v host didn't show any errors. Host and guest are running well since several months.
Even a reboot (first the guest, then the host) did help.
A fresh made backup doesn't bring errors or warnings.
A whole restore of the guest works well.
ONLY the file level restauration doesn't work.

Do you have an idea how this could be fixed?
Sincerely yours Marc

chances are very high, that it is an issue on the Hyper-V or guest-VM side.

Does that happen with all your VMs, or only one VM? If one VM, then I suggest to migrate that machine to a new VM.

You can also try to use the Other-OS file level recovery appliance (it's built for Linux VMs, but also works for Windows)

Best regards,
