It's one of those products that gets better with time! The product has improved since I first started using it over 10 years ago when we had only 4 computers backed up at once (we now do about 50).
We use this software primarily because our IT department does not want us backing things manually or having them come out every month - they just don't trust their own staff enough anymore so instead rely upon backups provided by third parties like ourselves who are trained professionals doing what needs done right way each day without fail etc.,etc..
