How to automatically download hard dirve contents to my passport

how can i automatically transfer all of the contents of my hard drive into my passport external drive.
what are the steps i need to take to do this?

Hello,

Depending on your drive, you should be able to do that with a backup software.

If you are trying to do a full copy of your drive including the OS files, you will need a cloning software.
