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.

It depends what I'm backing up and where it's backing up to.

I do local/lan backups at a much higher rate because there's more bandwidth to spare and effectively free storage. So for those as often as every 10 mins if there are changes to back up.

For less critical things and/or cloud backups I have a less frequent schedule as losing more time on those is less critical and it costs more to store on the cloud.

I use Kopia for backups on all my servers and desktop/laptop.

I've been very happy with it, it's FOSS and it saved my ass when Windows Update corrupted my bitlocker disk and I lost everything. That was also the last straw that put me on Linux full-time.
