Well, the traditional answer for this type of interface is "speed".
I reference the "Backup Copilot" product from SunSoft.  It was
a replacement for the traditional "dump"/"restore" programs and
went way, way, faster (at least for dumps).  And it used an open-by-inode
interface to get at the file data, as I recall.

The paper appeared at a LISA conference, but I couldn't trivially find
it in a minute of google searching.  Maybe someone can post a link
to it when they find a copy.
