Devels, I just came across tee() and splice(). They were introduced in 2.6.17, so relatively new, but not that new.
http://linux.die.net/man/2/tee http://linux.die.net/man/2/splice They allow data to be copied from one file descriptor to another without the data coming into userspace. If I was still an active developer, I think about modifying rdiff-backup to use them if there available. I doubt it would really impact the speed of rdiff-backup, but it seems like a fun project and I always liked learning new system calls.
