# System Reliability

***

### Summary

This section groups the runbooks used to keep Nodeum available. It focuses on backups and controlled failover procedures.

### Next steps

1. Set up and validate your backup plan in [Backup & Restore](https://docs.nodeum.io/data-archiving/system-reliability/backup-and-restore).
2. Review and rehearse single-site recovery in [Failover Procedure - One Site](https://docs.nodeum.io/data-archiving/system-reliability/failover-procedure-one-site).
3. If you run HA, confirm the cutover steps in [Failover - Active/Passive](https://docs.nodeum.io/data-archiving/system-reliability/failover-active-passive).
