Hello John, and thank you for choosing JUSTANSWER.com
I am very sorry to hear about your Iyogi product being delayed. It is very frustrating, i know
As far as backing up your computer to an external hard drive....there are really only 2 schools of thought on this topic.
1- Manually moving the files and folders to the external harddrive. (this is the most advanced, but also ensures NOTHIGN was missed...RIGHT!?)
2- Using a program to find, and transfer the files and folders FOR YOU. (this ca be tricky, as you have to trust the program to get everything)
Which do you think you would like to try?
