Difference between full snapshots and incremental snapshots
The differences between full snapshots and incremental snapshots in Amazon EBS are:
Snapshot Type:
- Incremental snapshots: These snapshots only store the changed data blocks since the last snapshot, making them more efficient and cost-effective for frequent backups.
- Full snapshots: When you archive an incremental snapshot, it is converted to a full snapshot that includes all the blocks written to the volume at the time the snapshot was created.
- Incremental snapshots store only changed data blocks since the last snapshot, making them efficient and cost-effective for frequent backups.
- When the increamental snapshot is archived, they are converted to full snapshots, that including all blocks written to the volume at the time of snapshot creation.
- Incremental snapshots are stored in the Standard tier by default.
- Full snapshots are stored in the Archive tier after being converted from an incremental snapshot.
Retrieval and Cost:
Also, refer Snapshot storage tier types and cost difference
- Incremental snapshots in the Standard tier can be retrieved quickly and without additional charges.
- Full snapshots in the Archive tier have lower storage costs but incur additional charges for data retrieval, typically around $0.03 per GB.
- Incremental snapshots are suitable for frequent backups and fast recovery.
- Full snapshots in the Archive tier are more suitable for long-term, infrequently accessed backups, such as compliance or regulatory requirements.
