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.

Every hour via Restic to a local Mino instance on my NAS. Once a day to backblaze B2. Once a week to an offline HDD in my fire safe.

Keep in mind the more often you backup the less total time each backup should take to run. If your backup software isn't too heavy to run and stores backups incrementally, there is little penalty to frequent backups.
