# OpenStack Backup Operations A cloud without tested backups is a cloud waiting to lose data. Backup operations protect the entire stack -- from the databases that store state, to the configurations that define behavior, to the volumes that hold user data. The backup hierarchy ensures that any component can be recovered independently, from a single Keystone Fernet key to a complete cloud rebuild. Backup planning starts with two numbers: **RPO (Recovery Point Objective)** -- how much data loss is acceptable (e.g., "no more than 1 hour of changes"), and **RTO (Recovery Time Objective)** -- how long recovery can take (e.g., "service restored within 4 hours"). These numbers drive every decision: backup frequency, storage location, retention depth, and automation investment. In NASA SE terms, backup maps to **Phase E (Operations & Sustainment)** as a core sustainment activity, and **Phase F (Closeout)** for data archive procedures. The backup hierarchy follows the same defense-in-depth philosophy NASA applies to mission-critical data: multiple copies, multiple formats, verified recoverability. ## Deploy ### Backup Infrastructure Setup **Backup scripts location:** ```bash # Create backup directory structure mkdir -p /opt/openstack-backups/{database,config,volumes,images,snapshots} mkdir -p /opt/openstack-backups/scripts mkdir -p /opt/openstack-backups/logs # Set ownership and permissions chown -R root:root /opt/openstack-backups chmod 700 /opt/openstack-backups ``` **Kolla
