Soündless Posted September 6, 2006 Share Posted September 6, 2006 How does Time Machine work?, all that info has to be stored somewhere, if you leave your computer on for 5 years, would you run out of space because of time machine?

Colonel Posted September 6, 2006 Share Posted September 6, 2006 With Time Machine, the information is stored onto another hard drive. That can be internal or external. Time Machine can be set to backup for I think a maximum of a year, but correct me if I'm wrong. Time Machine will alert you when your backup drive is full and it will let you delete certain periods of time to make room for the new backup.

Rammjet Posted September 6, 2006 Share Posted September 6, 2006 It first makes a complete backup and then only records the changes relative to that backup. So the incremental saves are relatively small. It uses the same mechanism as Spotlight to keep track of what changes, in the same way that Spotlight doesn't have to keep scanning your drive once the original scan has been completed.
