I’m new to QubesOS and have a couple of questions. First, I use a USB audio DAC for my headphones and speakers, but I find myself having to manually assign it to a Qube each time I want audio. Would it be a good idea to set up a sys-audio to route all audio, including my microphone, through there?
Secondly, on my previous system, I used Kopia for automatic backups to my external hard drive. I understand that backing up in QubesOS is quite straightforward, but how can I implement this? Should I create a Qube, attach my drive, and set up a script for automatic backups? Also, does QubesOS create continuous backups, or does it only update the backup when changes occur?
You may find Qubes Backup utility to be lacking in functionality. There is not currently any incremental backup, or specific file restore options, as an example. You trigger the backups. The utility does have it’s merits, but I found using it daily brought on additional undesired complexity. You may need to rename VMs pre/post restore. You may find the process difficult to streamline and storage intensive.
The direction I went (and others on the forum here) is to use Tasket’s Wyng Backup Utility. This is more inline with traditional backup procedures and far more flexible for automation. Here is a great guide I found success with:
That being said, it appears automation is up to the user. Plenty of building blocks here with qrexec, qvm-run, etc. However, using 3rd party utilities in dom0 does introduce a security risk.
