Restoring a Volume from a Backup
Via Horizon Dashboard
- Navigate to Project → Volumes → Backups.
- Locate the backup you want to restore.
- In the Actions column, select Restore Backup.
- Choose to restore to an existing volume or create a new volume:
- Restore to existing volume – Select the target volume.
- Create new volume – Enter a name for the new volume.

Via CLI
openstack volume backup restore <backup_id> <volume_id>
Key Notes
- Incremental backups depend on the existence of a full backup.
- Restoring from a backup creates an identical copy of the original volume.
- Backups are stored independently of the original volume and are not affected by volume deletion.
- At PSNC, backups are stored on an independent S3 backend for durability and resilience.
