When disaster strikes, simply boot from your backup and get back to using your Mac. With Carbon Copy Cloner, your data and the operating system’s data are all preserved on a bootable volume, ready for production at a moment’s notice. With ordinary backups, you’d spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data. Suppose the unthinkable happens while you’re under deadline to finish a project: your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. Carbon Copy Cloner backups are better than ordinary backups.
