You may be wondering what disk-to-disk (D2D) backup means. A great place to start is the dedicated Wikipedia page.
LBackup is designed for disk to disk backup. However, hard disks are not the only supported storage system. In essence if your operating system is able to mount a storage device within your file system. Then that backup media will be supported (possibly with a post action script which shuttles data to the storage system).
If the file system of your mounted storage system supports hard links and other meta-data preservation that you require for your backup then there is very high probability that you will be able to store your backup set directly to the file system of that storage media.
