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 still have drawings I made in MS Paint on Windows 95 when it had just come out, my first text document, and the first report I ever typed in grade school.

Btrfs snapshots of the root volume in RAID1 configuration with 8 hourly, 7 daily, 3 weekly, and automated rsync backups to NAS, with primary and secondary offsite, physically disconnected backups stored in sealed, airtight, and waterproof containers at two different banks prepaid storage and with advanced directive in the event of my demise.

Bit of a hobby really. I acknowledge it's completely unnecessary. I don't like to lose data.

Sealed, airtight, and waterproof but what if both banks burn down at the same time? You didn't mention fire-proof.

[–] henfredemars@infosec.pub 5 points 10 months ago

You got me there! Not fireproof. In that case I'm just hoping that having two off-site backups at different locations has me covered, but that's a good idea. I should consider fireproof foil.

You are backed up better than some enterprises...

Just wow.

Another perspective is data hoarding.

I have system images of machines of relatives who have died. Many of the photos that I have retained are the only ones. However, that was more an emergent utility than a motivating one.

How often do you update your off-site backups?

[–] henfredemars@infosec.pub 3 points 10 months ago

Monthly, alternating locations.
