If you create content you care about, then you must back it up so it will not be lost if your computer crashes.
1. You can backup to removable disks (CD-R, DVD-R, or flashdrive).
2. You can backup to an external hard disk (with Norton Ghost).
3. You can use a combination of techniques to further reduce your risk.
When your hard disk crashes the availability of your data can only be assured by restoring from a backup copy.
I can help you configure the backup of your valuable information.
