How Carbonite Works:
A small application on your computer
Carbonite installs a small application on your computer that works quietly in the background looking for new and changed files that need to be backed up. It looks and feels just like part of your computer, and is integrated with your operating system - there's no new interface for you to learn.
Completely automatic

When your computer is idle, Carbonite automatically backs up your new and changed files. You don't have to do anything! When you're using your computer, Carbonite goes to sleep so it will never slow you down or interfere with your Internet connection.
Secure and encrypted to protect your privacy

Carbonite takes data privacy and security seriously. All your files are encrypted before leaving your computer and are sent to Carbonite data centers using the same security technology used in online banking. Files remain encrypted at our secure data centers, so only you can see your files.
Get your files back with a few clicks

If you accidentally delete or otherwise lose files, it takes just a few clicks on your desktop to get them back. If your computer is damaged, stolen or "just dies" and you lose all your files, just visit Carbonite's website from a new computer. Within minutes you'll be able to begin restoring all your files.
