Chapter . Back Up Your Data
System upgrades, because they affect so many parts of your hard disk, and at such a low level, are occasions when problems are especially likely to occur. So I can’t emphasize this strongly enough: before upgrading, back up your data. The time you spend now may save you countless hours of frustration later.
Tip
