Using XP. Will be adding a separate internal hard drive, 30 gigs in size.

It has been many years since a hard drive has died on me, but it could happen. So, since I am thinking about backing up data, I might as well get the most that I can ask for.

My first concern is backing up My Documents on at least a daily basis. I bill and get paid for documents in My Documents, so I do not want to lose any. Any that are lost, means a loss in income.

Second, I have lots of software that are functioning very well. I do not want to have to try to convince a vendor that I paid for the software 2-3 years ago. I do not want to have to reload in software or configure software to work. The software works now and I want it to work an hour after a major crash.

Is there a software program which will put my entire existing hard drive data, software, etc, onto a backup hard drive and also update My Documents periodically? If my existing C drive crashes, can I rest assured that all I have to do is re-name the D drive to C, and resume working. Or, am I asking for too much?
