Back up your backup system itself, or rebuilding it becomes the disaster

Back up your backup system itself, or rebuilding it becomes the disaster
When the server dies, your beautiful backup config dies with it. Capture it:
— Export the cron schedules and the backup scripts to version control
— Document every destination, bucket name, region, and endpoint
— Store credentials for the backup targets OFFsite, separately
— Note retention rules and immutability settings in plain text
— Keep a one-page "how this whole thing works" outside the server
If recovering means first reinventing your entire pipeline from memory, you doubled your downtime. Fight me in the comments.
