I believe that this would cause your machine to always show up in the pending devices and thinking it requires a restore, as Mirage uses the BIOS UUID as a way to identify a machine. You could do a couple of things, archive the CVD and then it may appear as just a pending device. Delete the CVD, or do a clean state uninstall of the mirage client and or archive the cvd or delete the cvd and this should stop it from wanting to restore the device. You could possibly edit the upload policy to exclude the windows.old, but it is part of the wanova volume location and I am not sure we allow this. I would recommend just removing it based on the below KB
