I haven't seen that manner of command used for Qubes backup before. It looks like you're mixing together the qvm-block, qvm-usb, qvm-pci command attributes and options with the qvm-backup and qvm-backup-restore command attributes and options, which are different in this regard. See the commands below to see what I mean by different. qvm-backup -d name-of-AppVM-to-handle-backup '/path-to-backup-location' Also if you want to only include one or a few VM's, then; qvm-backup -d name-of-AppVM '/path-to-backup-location' work vault personnel Which will exclude everything else. But if you want everything, but exclude a few VM's, then you can type; qvm-backup -d name-of-AppVM-to-handle-backup '/path-to-backup-location' -x sys-net -x sys-firewall -x sys-whonix -s fedora-26 -x work I believe you can even mix both approaches, but I have never attempted this, nor read if it's possible. But logically it seems possible. To restore again, qvm-backup-restore, just reverse the same as above, for example: qvm-backup-restore -d name-of-AppVM-to-handle-backup '/path-to-backup-location/backup-filename' Note here, unlike the above, you will include the backup file when restoring. Furthermore, you can use the '--save-profile profile-name-of-choice' attribute to save frequent used backup patterns. Profiles are not important, but they are convenient and makes life easy. For example if you just need to do a quick backup of all your AppVM's but don't want to include the templates, then you can restore it with '--profile name-of-your-AppVM-profile'. This way you can make frequent smaller backups very quickly, but less frequent slow and large backups. The large backups are useful for situations you need to re-install but no security issues or desires to freshly clean anything, is needed. While the backup of your AppVM's, at least will save your work and data. So profiling makes it easy and very useful to quickly make backup's of the most important stuff on a frequent basis. For example to save a profile, something like this qvm-backup -d name-of-AppVM '/path-to-backup-location' work vault personnel --save-profile AppVMs In order to quick restore a profile, but remember a dom0 re-install likely removes backup profiles, though this is normally no big deal anyway. To use; qvm-backup-restore --profile AppVMs I remain uncertain if backup profiles can easily be transferred to a new fresh Qubes install. I assume there is no security issue with it too, but it's also something unanswered. Perhaps the profile is saved within the backup itself, or instead in dom0 somewhere. Either way, this should get you started. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
