Until the backups don’t work.
Untested backups can hold all sorts of surprises.
Sadly, testing backups is a lot of work and is rarely done.
Deja Dup has a nice feature in that every once in a while is spawns and verifies that the backup is retrievable
Not your problem… until the hosting provider publishes a press release about some recent fire or flooding in the data center that “only impacted less than 1% of our customers”… and you turn out to be among them.
For “super important” stuff, I keep closer to 10 copies spread around in different places. Normal stuff is 321, and everything else is temporary.
I have. Both server and backup lost, and all I got was a complimentary 1 free month. Not a fun time uploading everything again from the single local copy.
Now something similar is going on with Google for Business, where they’ve switched from “unlimited storage” to “actually, $300/10TB/month”. Like that’s going to happen (there are $100/100TB/month bare metal out there), but now I have to decide what to delete, what to keep, and what to downgrade from 321, to “temporary” single copy.
