So here's my question for you:
What's your favorite backup software for backing up to an external drive? I much prefer free software (open source is great), but if you have some compelling reason to pay money I'm interested in hearing that too.
I have tried Acronis TrueImage which is great because it images the entire drive, but sometimes I just want to have the files available on other computers without TrueImage installed. Also, it's not free.
