Coding horror has, after their mishap last week, declared International Backup Awareness Day. Speaking again as someone who has had this happen more than once, I have learned about backups and disaster recovery. In fact, I'm happy to say that the last time I had issues, when a bad controller brought down 3 drives simultaneously in my 5 disk RAID5 array, having an "offsite" (read: USB HD plugged into the back of the server) backup saved my ass. Previous times I haven't been so lucky :)
