Creates an automatic snapshot policy. After you create an automatic snapshot policy, you can call ApplyAutoSnapshotPolicy to apply it to any disks. You can call ModifyAutoSnapshotPolicyEx to modify a created automatic snapshot policy as required.

Description

When you call this operation, note that:

  • You can create up to 100 automatic snapshot policies in each region.
  • If a disk contains a large volume of data, the amount of time it takes to create a snapshot can take longer than the interval between scheduled automatic snapshots. In these cases, the second scheduled snapshot will not be taken. Assume that you set the automatic snapshot time points at 09:00, 10:00, 11:00, and 12:00. If the first automatic snapshot taken at 09:00 took 80 minutes to complete and ended at 10:20, the task scheduled for 10:00 will be skipped. A snapshot for 11:00 will be taken as scheduled.

Debugging

You can use API Explorer to perform debugging. API Explorer allows you to perform various operations to simplify API usage. For example, you can retrieve APIs, call APIs, and dynamically generate SDK example code.
