How often should I back up?
The answer to this question really depends on how often you use your computer. Think about what you did with your Mac in the last 24 hours, the last few days, the last week and the last month. If you would be unhappy losing data created within the last 24 hours, you should back up at least once a day. If you wouldn’t start to sweat unless you lost at least two weeks of data, you should back up once a week. Time Machine will create backups for every hour of the last 24 hours, every day of the last month, and every week past that until your backup disk is full. The important thing is to REMEMBER to back up. Either use software that automatically schedules itself to back up frequently or put reminders in your calendar.
