Backups. This is basic. As posted above, until you TEST your backup, you just don't know.
Stupid home computer was being backed up every week. Hey, I knew the backups were good: the software gave me a green check mark each week. When the (only) hard-drive failed, I sprang into action to prove my manhood. I put a new drive in, shoved the rescue boot disk in...and promptly found out that there was no backup. I learned. The next software I used, I made a backup and then removed the hard drive, simulating a total hardware failure/replacement.
If I were a CTO, that would be the ONLY strategy which would assure the system's redundancy. Take it offline (gracefully) and see what happens. Oh, make the vendors sign guarantees.
Maybe that's why I'm not a CTO?
