    I do backups the old fashion way of dumping everything onto a HD from time to time. I'm thinking of going the Time Machine route. I'm wondering if the HD you are using for backup has to be connect to your computer at all times for time machine to work.

    Only if you want it to do automatic backup. If you just want to do one a week or a month, just plug it back in and it will backup then. It will,every now and then, tell you that it hasn't done a backup in a while and you need to hook up a hd to do so.

    Awesome, thank you!

    Another questions... will it backup from multiple drives fine? Or does it only want to back up your system drive?

    Yes, it can backup multiple drives as well. Just check from Options that it is not in the Exclude list
