Can anyone recommend a local backup solution?

We have account managers here in my office, and up till now we've been providing them with Freecom tough drives and Freecom personal media suite. It works great, it kicks in when they plug the drive in and checks a bunch of folders we've specified, making sure the files on the tough drive are the same as the ones on the laptop. Unfortunately, it's broken in Windows 7, so we need another solution, as Freecom can't give us a date for when they'll offer Windows 7 compatibility.

Any recommendations? Ideally we want something with similar functionality, so online backup solutions are a no go.
