So ehm, tl;dr: KEEP DAILY BACKUPS. EVEN IF SOMEONE SAYS NOT TO.

7:48
Manager: Hey Tom, is the server down?
Me: Nah, should be ok, I just did some maintenance this sunday.
Manager: But I can't get [some work data from SQL server]
*Nervous giggle*

9:14: Some random off-site cunt they hired didn't read the notes that said "DO NOT REMOVE DATABASE [xyz]"
9:20-ish: Web don't even have the DB. And you said that we'll figure out what to do with backups later
*Suddenly manager starts to panic*
11:47: Found backup of the entire server on and old server that we had for spare parts, still running tho.
12:something: Everything back up and working.

Really glad I kept the old server running and doing daily backups. Saved our ass for the second time. And finally, new off-site backup is planned this week.
