Still ironing out a few bugs with the new system although overall I'm quite pleased with its performance.
One issue that I've wrestled with is finding a quality file backup application that's free and easy to use. I started with Comodo Backup but was unable to get file synchronization to to run correctly. The issue may be Windows 7 (or not) but I was more interested in backing up my files than in troubleshooting the application. That being said, Comodo is free and many have great success with it - so it's worth a shot.
Instead I chose Areca Backup, an open source backup application. It's very easy to use and performs as advertised.
They haven't certified it for Windows 7 yet, but I haven't had any problems with it. There's also a helpful online tutorial.
