When you eventually have a catastrophe, the data is simply gone. You know that feeling -- you just lost six years of family photos. Your kids being born, their first birthdays, their first everything. The answer to this is consistent and regular backups, placed on a schedule and handled automatically by your computer.

CCC 3.0 features a new interface designed to make the cloning and backup procedure more intuitive and more responsive. Users have better control over what gets backed up, and are provided with detailed information about the progress of their backup. In addition to general backup, CCC can also clone one hard drive to another, copying every single block or file to create an exact replica of your source hard drive. CCC's block-level copy offers the absolute best fidelity in the industry!
