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 .snapshot directory.
