How to use the back up tool?

I know how to make a comeplte back up, what i want to do is to update the back ups with the files that have been modified since last back up. how do i do that?

I haven't worked much with NTBACKUP but it looks like you can do differentials with it from command line.

If your just backing up files you could use robocopy. Its another free utility from MS for copying files. It has some nice filtering features like the ability to only copy modified and new files.

Or if your an ubergeek like me you can also use shadowcopy which has the nice feature to save versions although you have to remember to occasionally purge shadowcopies because they fragment.

Use the backup utility that comes w/XP and run thru the wizard. You can start with a complete backup, then schedule incrementals.
