An example of what the parent commenter meant is more like:

1. You write a DRL that says “we do a disaster recovery test annually to ensure that we can restore a production backup”.

2. It takes you 20 tries in 2026 to do a successful restore because your find out the first 19 times that your backup is broken and incomplete.

3. You never have to mention the first 19 tries to the auditors when you prove you did do a successful DR restore.
