I would like to setup an automated backup to my external hard drive each time it is connected to my PC using Synctoy 2.1. I just have some questions I would like answering first. My external HDD is used in conjuction with my WD Media player and therefore spends most of its time in the living room, I only intend to plug it into the PC once per week. When I do this I would like it to automatically backup all the specified folders directly to the HDD. How do I assign a permanent drive letter to an external HDD and how would I setup an automatic backup on plugin to this drive using Windows 7 home edition.
