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 worked at a datacenter that wanted to change backup vendors, as we dug into the details we found out that the agent based backups needed an agent running on the machine to restore to and they didn't have a linux agent. Despite this obvious problem mgmt chose this vendor. It didn't take long before sysadmins were rebuilding linux boxes from scratch in the wee hours. I left shortly after.
