Backup question

[Mel]

I write a lot of word documents and want to do frequent backups on those
files and a couple of program files. I did my first backup using Windows
XP.

I selected the files and folders I wanted to backup and did an new backup I
named "First Backup". In advanced options I chose a differential backup
which I used in Windows 98.

Now I want to do a subsequent backup but it looks like I have to re-check
the files and folders I want to back up all over again. Am I missing
something here or is there a way to do subsequent backups using my "First
Backup" without re-checking the file and folder boxes again?

If it is just document files the best method is to burn them to a CD instead
of using a backup program.

This way they can be retrieved from any machine without a hassle.
