The usual rule when making backups is that you need 3 copies, one of them offsite. A cloud storage service counts as an offsite copy, but you still need two more, typically one on your computer and one in cold storage (ex: external hard drive).
Treat cloud storage like you treat your hard drive, it can fail at any time. The failure modes are different: mechanical failure vs losing access to your account, but the end result is the same: the system is unreliable and you have to engineer around it.
- Aachen 1y agoI think applying these traditional schemes to SaaS environments (now called cloud) can be misleading When people want off-site backups, the server owner can say they've already taken care of that. I'd say that having a copy under your own control is a separate checkbox we should include!

- Too 1y agoGood advice. Though I’d say you can count the cloud storage as 2 copies. They typically replicate the data to three drives, that covers all the typical failure modes you’d normally get when running a drive yourself. Then with a simple click you can even get a replica in another region. The third backup being in a decoupled system on site is what you now count as your ”offsite” backup. Having this last copy is non-negotiable, no matter how many 9s S3 claim to have.
