Macintosh Time Machine backup
Setting up a Time Machine backup on your Mac can save your data in the event of a catastrophic hardware failure. A Time Machine backup, once established, runs in the background and is a good way to ensure your data has a fairly recent backup. If hardware failure occurs on your Mac, a Time Machine backup can also serve as a quick restore option to a different Mac or hard drive to get you back up and running in the shortest time possible. A Time Machine backup can be configured for either local or network shares. This document is meant as a simple how-to for a local backup.
