A related thing to look at would be the Plan 9 file system. http://www.cs.bell-labs.com/plan9dist/
It is an entirely different design using copy-on-write and a form of snapshotting such that something like:
cd //2001/12/25/foo
puts the user in directory /foo as it was at daily backup time on Christmas day last year.
The original Plan 9 system used WORM drives with hard drives acting as cache. I suspect the design could work without WORM. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
