Rolls back a disk based on a snapshot.
Operation description
- You can call this operation to roll back a disk only if the associated simple application server is in the Stopped state.
- After a disk is rolled back, all data changes that are made from when the snapshot was created to when the disk is rolled back are lost. Back up disk data based on your needs before you roll back the disk.
Precautions
After you reset a simple application server, the disk data on the server is deleted. Snapshots created before the resetting operation are retained but cannot be used to roll back the disks of the server.
QPS limit
You can call this API operation up to 10 times per minute per account. Requests that exceed this limit are dropped and you may experience service interruptions. We recommend that you take note of this limit when you call this operation. For more information, see QPS limits.
