If Ian is moving 7 gigs of data from milaukee wisconsin it seems likely
the network will cause a problem and drop the transfer. rsync has
compression, uses rsh and it will pick up where it left off if your use
the --partial option.

rsync -azv --partial file host.domain.org:/directory/file

You can also use rsync over ssh, but that would be slower than rsync.

rsync -azv --partial -e ssh file host.domain.org:/directory/file

I don't know if rsync has the 2 gig file limitation.  A year old post on
the rsync page http://rsync.samba.org/rsync/fom-serve/cache/50.html lists
an unanswered question about the 2 gig limit on AIX.  I have transferred
more than 2 gigs at a time with rsync, but it was a lot of files.  On one
occasion I had a problem with rsync when I tried to transfer a 20 gig disk
with thousands of files, the machine ran out of memory building the file
listing.

Thanks,
Chuck
