I love that GoodSync is fast and efficient. It's not overly complicated to perform a quick one way sync of files. I mostly use it to perform what's essentially a backup of my work laptop to a portable hard drive while I'm not in the office. I also use another copy I have at home to perform a quick sync of a folder or drive that I need to ensure doesn't get lost if something happens to it. The configuration of the software is easy and straightforward and it just WORKS. There's a number of backup software suites that just seem overly complicated and once you start executing them you can't see what's happening. GoodSync allows you to see all of the files that are being sync'd. Love it and would recommend to others!
