We're in the same business as LXLabs, and believe me, backups are not as common in the hosting industry as we'd all like or expect.
Even when it is made easy and automatic, we still get folks asking us for help with recovering or repairing data that could easily be recovered from backups...if they actually kept backups. And, of course, secure off-site backups are almost unheard of (actually making backups secure from attackers that have root access is a pretty hard problem; or, at least, one that requires two machines).
Anyway, I've experienced it a few times in my career, and I can say with confidence that there are very few worse feelings than knowing a mistake you've made has caused someone major data loss.
Many of the lost accounts opted for the economy plan that did not include backup... they got what they paid for. No backup unless they took it upon themselves.
