You will only have to restore files that have changed since you last made the clone. You computer will be in the same state as it was when you made the clone. The process of recovering from a disk failure with a clone is much faster and more efficient since you can connect your cloned disk and boot from it. This means that you must first reinstall your operating system and then restore your files from the incremental backup on to the newly installed operating system. Most incremental backup solutions, including Time Machine and CrashPlan, do not backup your entire computer including all the system files and boot records. Let me emphasize that maintaining a recent clone is the key for you to rapidly recover your data in the case of a disk failure or theft. CrashPlan also has the advantage that it works equally well on Windows and Linux. In these cases CrashPlan provides a solid alternative for local backups in addition to network backups. At the same time, Time Machine has some notable quirks and limitations that can make it far less desirable in some circumstances. Its ease of use can make the difference between having backups and not having backups for many. The primary interface is a single on or off toggle switch. I found Time Machine problematic for my own setup, for reasons I explain below, so I now use CrashPlan for both local and networked backups.įor most people with configurations that are not highly customized or complicated, Time Machine is a great “set and forget backup” solution. In my recent article, A Simple and Effective Backup Strategy for Mac OS X, where I recommended a three part backup system: 1) a full disk clone, 2) local incremental backups with Apple’s Time Machine, and 3) networked incremental backups with CrashPlan.
