Smartware can be uninstalled (or not installed in the first place) if you have no wish to use it.
You can use any backup program you wish.
It does also depend on what you're trying to back up. If you already have your system files and programs backed up, and just want to safely store your personal documents, then you're who Smartware was designed for. AFAIK it won't backup programs or any other system files, so you'd have to be using something else for a system backup beyond Smartware anyways.
