I have a 1TB external hard drive and I'd like to periodically schedule backups of my "Libraries" in Windows to the external drive. I'd prefer if it could detect what files have changed and periodically transfer them to the drive instead of I having to do it manually.
Is there a way in Windows 7 to do this automatically? If not, what are some external tools (preferably free) that I can use for this?
EDIT: I've used Windows back-up and I find it restrictive for detecting changes and backing up automatically. That's all that I'm aware of. My WD hard drive had something for this but the application doesn't work any more and it wasn't that good either. So, I wish to know what are my options.
