Backup and recovery is the work of taking regular copies of a live system and, critically, testing that they restore. An untested backup is a hope rather than a plan, and the difference only shows up on the worst day.
Let's TalkA backup nobody has restored is a hope, and the day you find out is the worst possible day to find out.
The difference between an incident and a disaster is usually whether recovery worked.
A tested figure lets the business plan around it instead of guessing in the middle of the event.
Most restores are not attacks, they are somebody deleting the wrong thing.
This is one part of our maintenance and support work. Engagements rarely stay in one box: a platform rollout turns into something custom, and both then need looking after. That is why our software development and implementation practice treats implementation, custom development, and ongoing support as one continuous piece of work rather than three separate vendors.
