Snapshot billing

Snapshot billing

This topic explains the billing methods, unit prices, and billing examples for snapshots.

Notes

Snapshots are billed on a pay-as-you-go basis. The cost is determined by the size of the snapshot and how long it is retained. Billing stops once all snapshots have been deleted and all auto-snapshot policies have been removed from volumes.

Billing method

Snapshot size

For snapshot billing details, see EBS pricing details.

Billing method	Description	Unit	Related documentation
Pay-as-you-go	A post-paid model where you use resources first and pay later. The billing cycle is one hour. Formula: Snapshot cost = Unit price × Snapshot size × Retention time	¥/GiB/hour	Pay-as-you-go

Cross-region snapshot replication

Replicating custom images across regions requires replicating the associated snapshots. This incurs cross-region snapshot replication charges.

Data transfer cost for replicating a snapshot across regions = Unit price × Snapshot size

Examples

Assume you have a 500-GiB snapshot in China (Beijing) for 20 days. The snapshot cost is calculated as follows:

Snapshot cost = 0.0001375 × 24 × 20 × 500 = ¥33
