About Mozy backups
Don’t take chances with your hard-won book pages! Every writer should regularly back up his or her work — ideally to an off-site server. Mozy is one such service provider.
From the site:
Founded in 2005, Mozy is the world’s most trusted online backup service for consumers and businesses with more than 6+ million customers and 100,000 business customers backing up 90 petabytes of information to multiple data centers around the globe.
Services & features: Automatic backups take place while your computer is not in use. Scheduled backups can be performed daily or weekly at a specified time of day. After the initial backup, Mozy only backs up new or changed portions of files. This saves bandwidth and ensures future backups are lightning fast. Users can also access their backed up and synced files on their iOS and Android devices.
