Bucket Snapshots
A Snapshot is a point-in-time, read-only image of a Bucket. It captures the exact state of the bucket at the moment of creation, allowing users to access historical data or perform backups without interrupting ongoing write operations.
Snapshot Key characteristics
- Instantaneous: Snapshot creation is an O(1) operation. It utilizes metadata within the Ozone Manager, making it extremely fast regardless of the bucket's size.
- Efficient: Snapshots do not duplicate data blocks physically. Storage space is claimed only when the live data is modified or deleted, ensuring storage efficiency.
- Accessible: Users can access snapshot data through the virtual
.snapshotdirectory.
