You know, if the backend DB is less than 2 GB you could put this on a dropbox folder (dropbox.com) and have a "backup" in the cloud free and with dropbox you have the option of having the client installed on other workstations in your office and have it replicate the DB dump on your LAN for you. That way you have both an on-site and off-site copy of the DB... or I think mozy.com still gives the first 2 GB free of backups free.

In either case you would just have a cron job dump the DB to a mozy backed-up folder or a drop box folder and you wouldn't have to do anything else... other than periodic test restores to make sure what you are backing up is good.

I don't work for either company but am a happy customer of both.
