While we're on business continuity plans, I'll share something that I ran into some years ago. The organization I was working for thought they had done everything correctly. Warm site servers, offsite backups, the whole gamut. Low and behold, disaster strikes and we lose two critical servers that run mission critical applications and are worthless without the backend database. The Restore Time Objective was 12 hours. The servers were powered on and network accessible within 2 hours. Restore from the backup tapes took another 37 hours.
This isn't about testing backup. It worked flawlessly, as designed, at the speed of the tape. Turns out that if your RTO is 12 hours and you budget 9 of those for restore from backup, make darn sure that your backup/restore solution is capable of meeting that timeline. Failure to do so is most certainly a career limiting move.
