I store all mine on a dedicated home NAS. Raid 5+1, over 4 2tb drives. That way I have drive failure redundancy. Anything truly important I store backups on an additional external drive that can be grabbed quickly in an emergency.
One of my old companies had an actual name for those of us in that DevOps role. It was called the swat team. We were the ones called in when it absolutely had to be done yesterday. Did it suck? Sometimes, but when we said something needed done, management actually would listen instead of blowing it off.
