Ok, I just did a quick test. Full backup to LTO-3, added some files,
incremental to disk. In bconsole -> restore -> 3: Enter list of comma separated
JobIds to select -> entered the two jobids -> marked the directory with the
added files -> done


The job will require the following
   Volume(s)                 Storage(s)                SD Device(s)
