mirroring without a network

[Helmut Jarausch]

Hi,

this might be offtopic - please excuse if it turns out to be.

I have rather big ( > 20 Gb) source archives on two different machines.
Unfortunately there is only a very slow network connection between these
machines.

To synchronize these two archives (directory trees), I'd like to
generate a directory tree of signature files (instead of the real ones).
Then I would copy only these to the other machine. There the tree of
delta files could be saved to some CDs and carried back to the first
machine.

Has anybody an idea how this could be accomplished - or is there even
some software for this?

Many thanks for a hint,
