Backup metadata volumes
Backup metadata volumes are point-in-time snapshots of the current metadata, and provide extra protection before major configuration changes, refreshes, or migrations.
Backup creates a point-in-time copy of the current in-memory metadata without activating it. You must create a backup metadata volume in any of these conditions:
- As part of an overall system health check before a major migration or update.
- If metro node permanently loses access to active meta-volumes.
- After any major migration or update.
