Over the internet for file sync. Desktop devices.

As far as I know, acupuncture has only one or two indications in which it performed better than a placebo. Interestingly the exact position of the needles didn’t matter at all in any indication.

This is a great hint, thank you. I just discovered that the official restic docs recommend this method too

Thank you!

This might be a good idea. It would only work for files that allow read access for the group, but that should be fine

Restic uses smart Delta backups, creating a tar before the restic process would defeat the purpose. The permission issue is the same, as I need to have access to the Files either way.
