Depends on your network of course but it doesn't surprise me that
sending a large file over a network would take longer than the local
backup, especially during the day. Have you considered getting a tape
drive to do your backups - they're not all that expensive, certainly a
lot cheaper than losing your data would be :)
Also, as someone else mentioned, consider doing a differential backup
during the day rather than the full backup. It's just one more step if
you need to restore, and it should be much smaller and faster than your
full backup.
