Create or modify an automatic snapshot policy

Snapshots can retain the disk data status at a certain point in time for data backup or custom mirroring.

Note

Starting from March 28, 2017, the snapshot service will start charging. For more information about snapshot charges, please see Snapshot Commercialization FAQ.

When setting the automatic snapshot creation time and repeat date, you should try to avoid business peaks, because creating a snapshot may slightly reduce the performance of the disk and cause a brief moment of slowdown.

An account can create up to 100 automatic snapshot policies in one region.
