As a suggestion, it may pay to modify the script, use ssh shared key
authentication and scp for the upload and md5sum the files both
before the transfer and after the transfer on the remote system (scp
is not really necessary but shared keys allow you to do things like..

quite easily to ensure that your files copied ok.)

Doing verification on the integrity of the archive before deleting the
older versions is usually considered a good thing [tm]

Excellent idea except the remote machine is Windows and I know almost
nothing when it comes to writing shell scripts. This "script" was a feat
in itself.

Okie dokie - in that case, you could probably expand your script to re-download the files via ftp once they had been uploaded. Then do the checks against the original (download them as a different filename or to a temp directory)

Basically, you have file integrity issues, the only real way to solve these if to verify the integrity of the files when you upload/download them.

Out of curiosity, where did you try to gunzip/gzip -t the files ? and if they were on a windows box, how did you get them back to the unix box ?
