Restoring a backup

Blue/Green restore of a PostgreSQL database — initiate, validate before switching over, or cancel.

Nubiecloud restores in Blue/Green mode: the backup is first restored onto a standby cluster, which you validate before it becomes active. That way you avoid any unplanned switch onto a faulty copy.

The journey

  1. Initiate the restore. From the backup list, pick a backup and start the restore. Nubiecloud prepares the standby cluster from that snapshot.
    • Status: pendingin_progress.
  2. Wait for the preparation. When the standby cluster is ready and healthy, the status moves to awaiting_validation (waiting for your validation).
  3. Validate the cutover. You confirm: traffic switches to the restored cluster, which becomes active.
    • Status: completed.
    • ⚠️ Validation is irreversible: it immediately switches production onto the restored copy.
  4. Or cancel. As long as the restore is pending or in_progress, you can cancel: the standby cluster is torn down and your active database stays unchanged.

Safety of the process

  • A restore can only start from a backup taken from the active cluster (protection against data loss).
  • If the standby cluster has a prolonged problem, Nubiecloud cleans up automatically and marks the restore as failed — without touching your active database.
