Backing Up Your System

If you use a computer, at some point, your system will crash, a disk will fail, or some other problem will happen (perhaps you will delete something you didn't mean to) and you will lose data you would rather not lose—maybe not today or tomorrow, but it is the inevitable nightmare. Think of the information you have on your Mac at this very moment that would be difficult—if not impossible—to reconstruct if your computer bombed and destroyed it. This data might be a report for work, a school project, your tax information, a complex spreadsheet, or even the great American novel on which you have been working. (For example, imagine that you have 2,000 photos in your iPhoto Library covering the last few years. Now imagine that the disk on which these images are stored dies. Losing all those pictures forever is not a pretty picture, is it?) Whatever the information, rest assured that some day, somewhere, somehow you will suddenly lose it. When that happens, you will want to be able to restore all the information on your Mac so you can quickly re-create your data. Backing up is the means by which you ensure that you can always preserve most of your work, no matter what happens to your Mac.

Backups: Insurance for Your Data

You need a good backup for more than just catastrophic failures of your hardware. I'll bet that you have accidentally deleted a file right before you needed it again. If you have a backup, you can quickly recover a document you accidentally delete. Or perhaps you edited a document and discovered that all your changes were actually worse than the original. You can use your backup to bring the file back to the way it was. If your Mac is ever stolen or destroyed, your backup will enable you to recover from potential disaster.
