An option should be provided to allow a user to take a snapshot of the destination cluster of a Cloud Backup restore before the restore is performed so that they can easily "revert" the restore if they need to (by just requesting a restore using the snapshot that was taken just prior).

It's possible to be in a situation where you've selected an incorrect snapshot for restoring or that you'd supplied the incorrect cluster for the snapshot to occur (this is less likely to happen in the UI than it is to happen programmatically via the API). Taking a snapshot just before restoring would mitigate the risk of these restore operations by allowing a fallback snapshot to restore from.
