Everybody who works in IT knows how essential backups are.

Turns out one of our customers, a bank, hasn’t had a working backup in two weeks. Because the backup run takes 49 hours. Our colleagues who set the infrastructure up – all of them contractors – just shrugged. “It’s not our duty to debug this, it’s surely a network problem.”

I just did the math, and their backup should take about 5 hours at full network speed. But five hours is still too much. In my opinion this is already a case where you should work with snapshots.

We had a bit of a discussion about the importance of backups with one of the contractor. He didn’t really understand that missing backups can, in the worst case, utterly destroy a company. I bit my tongue and didn’t ask him to please stop working in IT.
