file backup like scanreg need

Are you saying that you want to make backup of registry, like scanreg do ?
If so make a batch file that do it automatically, or you can do it manually or you can set up a task to do it whenever you want.

If you want backup solutions for other files, search the forum, RASTABT has decribed a good one that I use. Search forum for this.
