Restoring a full backup to a point in time is 'easier' with full backups. It's heavy on storage/networking relating to the operations. Delta's maintain a reference to their parents so full backups are what you get when you restore from a specific delta... with the efficiency in networking/storage as a value add. It would be nice to see delta's in KVM.
