That seems to be the point of LTFS. It allows solutions like rdiff-backup to write to tape without modification. It presents a filesystem interface to rdiff-backup and translates that into tape commands on the backend.
Hm... Good point, I didn't consider that.
LTFS seems to work best with large files. rdiff-backup makes no effort to consolidate small files, but if your files being backed up, it should perform well.
Yes, lots of large files.
Spanning tapes with LTFS would be the big question. A quick google shows that it may be possible. I'll have to dig deeper.
If LTFS allows a raid-like solution over multiple tapes :-) it'll be similar to technology that was available long ago with tape libraries.
Okay, it needed fancy robotic self-loading tapes, but I'm sure I worked with it on a Perkin-Elmer (or was it UniVac) mainframe back in the 80s. Files that weren't accessed for a while were shuffled off to tape, and when you tried to access them they were retrieved.
