Web site backup and upload: rsync over sshfs (GoDaddy or other hosting with ssh access)
Other good people provided ideas for this solution:

For some reason GoDaddy jailed hosting does not provide rsync, while it allows ssh user sessions to the host. It's not obvious how to move big chunks of data without "resume" functionality. Even worse for backup needs... Here's one of possible solutions based on my own experience. I hope this post could help someone too :)
