I'm paranoid that one day soon my 3 year old 40gb hdd is going to die. So I'd like to be proactive and find a fast reliable backup method to backup everything including windows, setup files, etc onto.

What would everyone recommend? A USB tape drive? Secondary HDD? CDR? Portable USB hard drive?

What do you currently use?

Any advice would be appreciated and will help me sleep better at night!

Thanks
