While my backup image files are far too large to consider
an RS232 transfer (my backup image files are 1 GB),
I would still suggest that if you are performing a backup
of your entire drive (or just partition), Ghost is an
excellent program to produce a compressed image
file first.  After that, you will have a relatively small
file to transfer.

There is probably one restriction that you may not
realize at first glance.  You will require at least TWO
drives (or partitions).  The compressed image file
of the C: drive (or partition) must fit completely on
the unused space of the second partition.

Of course, for the best transfer rate, it is useful to
have two physical drives and to compress the C:
drive onto the second physical drive.

After the backup is complete, you will be able to
transfer a much smaller compressed image file to
your remote system.
