Backups and failover you can trust
Disaster recovery is only useful if the team has actually tested the restore path.
Backup jobs are easy to set up and easy to ignore. Recovery is the part that matters.
A good disaster recovery plan covers where backups go, how often they run, how long recovery should take, and who is responsible when something fails. It also needs actual restore tests, because a backup that cannot be restored is just a comforting story.
The best disaster recovery work makes the team calmer because they have already practiced the worst day.
