Backup Metadata is the descriptive information of a backup: inventory, index, dates, objects, dependencies, checksums, or restore settings.
Simple definition
Backup Metadata is the descriptive information of a backup: inventory, index, dates, objects, dependencies, checksums, or restore settings. It belongs to the Backup / PRA vocabulary and is useful when reading architecture diagrams, product documentation, logs, or administration procedures.
What is it used for?
Its main purpose is to locate data, reconstruct chains, and drive restores without rereading all backup storage. The practical value depends on the surrounding architecture, security model, and operational requirements.
How does it work?
Backup software stores this metadata in a catalog, database, or files associated with restore points.
Key points
- Scope: The descriptive information of a backup: inventory, index, dates, objects, dependencies, checksums, or restore settings.
- Operational goal: Locate data, reconstruct chains, and drive restores without rereading all backup storage.
- Implementation: Backup software stores this metadata in a catalog, database, or files associated with restore points.
Points to watch
A backup is reliable only if restore is tested; document RPO/RTO, retention, immutability, and chain dependencies.
In short
Backup Metadata = the descriptive information of a backup: inventory, index, dates, objects, dependencies, checksums, or restore settings. Use it when you need to locate data, reconstruct chains, and drive restores without rereading all backup storage.
