How often do you back up? (lemmy.world)

I was wondering how often does one choose to make and keep back ups. I know that “It depends on your business needs”, but that is rather vague and unsatisfying, so I was hoping to hear some heuristics from the community. Like say I had a workstation/desktop that is acting as a server at a shop (taking inventory / sales receipts) and would be using something like timeshift to keep snapshots. I feel like keeping two daily and a weekly would be alright for a store, since the two most recent would not be too old or something. I also feel like using the hourly snapshots would be too taxing on a CPU and might be using to much disk space.

I have autocron jobs that sync various server directories to a daily backup (on the same server), then sync that backup once a week to the weekly backup, and once a month take a tarball snapshot of the weekly backup.

Every once in a while I plug in a HDD on USB and take a Borg backup of the monthly dir. Borg does compression and deduplication (and encryption if you want to). I should be doing this also once a week but sometimes I'm lazy and leave a few weeks between them.
