I was just assuming that if a real backup is made, it would be made on a separate, and typically removable, medium. One of the many purposes of a backup can be to prevent that system's destruction could cause data loss. If backup is made distantly or on a removable media, backuping the snapshot gives ability to read all files, except for data that is encrypted in the snapshot. In a persistent system, the problem is that nothing that is unencrypted can be paged out or snapshot, and this could (I don't have benchmarks or knowledge to tell) have serious performance impact.
