The  tricky part is the way the remote transfer comment (ssh, rsh or some
FTP script) is called by the tar comment. Basically it gets fed all the
data as input, and so doesn't have much opportunity to split it up. 

If I was creating a totally new backup module I'd have more flexibility,
but since the Filesystem Backup module works by calling the tar and dump
commands I have to fit in with the way they do things :(
