Look here Mozy Remote Backup:
Free remote backup is finally here! Download and install Mozy to ensure your data is safely backed up at a secure, remote location.
Mozy is a secure, automatic remote backup service for any PC in any home or office. It’s simple to install and configure. No external hard drive, expensive subscription services, CD’s or DVD’s to burn. All you need is a broadband connection and you are ready to go!
This is a beta product and as such I don’t recommend it as your primary back up for office data. However it is worth looking at for future reference. Also for dental data we need a HIPPA conformant back up.
