Test restore your backups (self.sysadmin)

Went to do a test restore of one of my databases and I noticed the dump files over the last few months were all 0kb. Glad I caught it this way and not because I needed to restore. Put it on your calendar, schedule a test restore of your critical stuff a couple times a year. I know y'all are busy but it is worth the time and effort. A backup you can't actually restore isn't a backup at all.

I started out in a big iron shop in the 90s. I was in charge of backups. We had an outage after a power loss, and the generator not kicking in. Our local backup set didn’t restore. The basement set, in a fire/waterproof safe didn’t restore. The off-site set restored.

The hours between the first fail and success were pure terror.
