Qubes creates a "snapshot" when you start a VM using reflink copies. If you look at "/var/lib/qubes/appvms/<SomeAppVM>" (or other btrfs pool) on dom0 you will see some "private.img.XX@XXXX-XX-XXXX". This files are snapshots from that date before the AppVM was started. Currently you can use 'qvm-volume' for revert some image to an older state but you will lose the present image. If you want to start an older image you can create a new VM and overwrite his 'private.img' with some "private.img.XX@XXXX-XX-XXXX". Hopefully in the future this could be improved, I would like to just start a DispVM based in a snapshot using few mouse clicks or a single command. In any case I recommend you to do regular backups ;) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
