If you no longer need a data disk, you can release it. Otherwise, we continue charging you for it.
Warning: Releasing a data disk is a permanent action and cannot be reversed. Once deleted, the original data on the data disk cannot be restored. We recommend that you proceed with caution.
- Make sure that the data disk is in the Available status. If the data disk is in the In Use status, detach it from the instance in the ECS console.
- Make sure that you have backed up all the data you need in the data disk. You can create snapshots for backup.
To release a data disk, perform the following:
Log on to the ECS console.
In the left-side navigation pane, click Disks.
Select a region.
Find the disk that you want to release, and in the Action column, select More > Release.
In the Release dialog box, read the note and click Confirm Release.
Now you have successfully released the data disk.
