@TheGibson i've mentioned mine before. three databases needed upgrading. i was working from home, and (um) may have had a glass of wine as i worked. i backed up the databases. i dropped the databases. i restored the first two databases without issue. i went to restore the third, the smallest and least important (but still pretty important, as it linked customer names to directories) - and...

...i couldn't find the backup.

gradually it dawned on me that i must not have made a backup.

we managed to restore most of them, but for several weeks afterwards we had customers ringing up asking where their websites (it was an ISP) had gone

lessons learned:

don't drink and datait's not backed up if you can't restore iti habitually overestimate my executive function, even taking point 3 into account
