Volume-Level Backup is a backup that protects a logical volume or partition as the primary unit.
Simple definition
Volume-Level Backup is a backup that protects a logical volume or partition as the primary unit. 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 restore a complete volume while preserving filesystem structure and data. The practical value depends on the surrounding architecture, security model, and operational requirements.
How does it work?
The engine reads volume blocks, often from a consistent snapshot, and stores required blocks according to the full/incremental method.
Key points
- Scope: A backup that protects a logical volume or partition as the primary unit.
- Operational goal: Restore a complete volume while preserving filesystem structure and data.
- Implementation: The engine reads volume blocks, often from a consistent snapshot, and stores required blocks according to the full/incremental method.
Points to watch
A backup is reliable only if restore is tested; document RPO/RTO, retention, immutability, and chain dependencies.
In short
Volume-Level Backup = a backup that protects a logical volume or partition as the primary unit. Use it when you need to restore a complete volume while preserving filesystem structure and data.
