Rolling back volumes using snapshots

Rolling back volumes using snapshots

You can use a snapshot to roll back a volume in case of a failure or data loss.

Prerequisites

The snapshot you want to use is "Available".

No snapshots are being created on the volume you want to roll back.

Currently, you can only roll back snapshot data to the volume from which the snapshot was taken. Make sure the volume still exists before rolling back.

The volume must be in one of the following statuses:

Available (not attached to an instance). You can perform the rollback directly.

Attached (attached to an instance). The corresponding instance must be stopped before you can perform the rollback.

Notes

We recommend creating a snapshot to back up the current data before rolling back.

Even after extending a volume, you can roll it back using a snapshot taken beforehand.

If the volume is attached, do not power on the instance during the rollback process.

If you extended the volume after creating the snapshot, you must extend it again after rolling back. For more information, see Extending a volume.
