ApplySnapshot

最后更新时间：2023-03-16 16:17:27

1. API Description

Domain name for API request: cbs.tencentcloudapi.com.

This API (ApplySnapshot) is used to roll back a snapshot to the original cloud disk.

  • The snapshot can only be rolled back to the original cloud disk. For data disk snapshots, if you need to copy the snapshot data to other cloud disks, use the API CreateDisks to create an elastic cloud disk and then copy the snapshot data to the created cloud disk.
  • The snapshot for rollback must be in NORMAL status. The snapshot status can be queried in the SnapshotState field in the output parameters through the API DescribeSnapshots.
  • For elastic cloud disks, the cloud disk must be in UNMOUNTED status. The cloud disk status can be queried in the Attached field returned by the API DescribeDisks. For non-elastic cloud disks purchased together with instances, the instance must be in SHUTDOWN status. The instance status can be queried through the API DescribeInstancesStatus.

A maximum of 20 requests can be initiated per second for this API.
