This is probably the stupidest question ever, but what exactly is a nandroid backup and how does one create one? I'm assuming it's a complete backup of all info (date, apps, OS...) on your phone (SD card, main memory...). How exactly does one create this? Is it a matter of using Titaniaum backup to backup to your SD card then simply copying all the contents of the SD card to a folder on your computer or is there more to it? It might be that easy and that's why I haven't found a guide. If there's more to it could you advice me please? Thanks in advance.
