　　Aliyun How to roll back a disk

If there is a problem with the current system, and you want to roll back data from one disk to a previous point, you can roll back the disk implementation, provided that the instance has a snapshot.

　　Note :

After the rollback, data is lost from the time the creation date of the snapshot being used to the current time.

Snapshot rollback is an irreversible operation, and once the rollback completes, the original data will not be recoverable, please proceed with caution.

The operation is as follows:

Log on to the Cloud Server Management Console.

Click an instance in the left navigation. Then select the region at the top of the page.

You need to stop the instance before rolling back the disk. Select the instance for which you want to roll back the disk, and then click Stop below.

Click the name of the instance. Then click the snapshot of this instance on the left. Select the snapshot that needs to be rolled back. Only one snapshot can be selected. Then click Rollback Disk .

In the Prompt box that pops up, click OK .

When the snapshot rollback completes, the instance enters the state of the startup until the instance enters a running state.

Error handling

When you roll back a disk, if you encounter the following error: The current state of the resource does not support this operation

This is because the server has not been completely stopped, and the rollback disk requires the instance to be fully stopped before it can operate, that is, the state is stopped . Either a stop or an instance in the startup cannot roll back the disk operation.

Please wait patiently until the instance is completely stopped before rolling back.
