Instead of doing a complete download if something went wrong, I think it is
better to use the ftp restart command (from the ftp man):
restart marker
Restart the immediately following get or put at the indicated
marker. On UNIX systems, marker is usually a byte offset into
the file.
which means that if you have a the first X bytes of a file, you should
do 'restart X' before you try to get the file again.
