    Most people use NAND backups to be able to play around with the system files with no fear of a permanent brick. But it is used to transfer savefiles and stuff from one Wii to another by some people, because it's easier than copying each savefile one by one to the SD card.

    But to use a NAND of a Wii in another you need to change the keys and other stuff, and if the new Wii has a bad block where there was vital data, it just won't work. So I had an idea: what about an app that doesn't backup the entire NAND, but instead copies every individual file in the Wii in a folder in the SD card? Then to restore them in another Wii, the app would copy (or replace if that file already exists) every file to the new Wii. I'd be like an automated tool to copy all the channels and savefiles from a Wii to an SD card and back (and maybe even IOSes).

    Now this is only an idea; I have zero coding experience, and I don't really expect anyone to do this. I just want to suggest the idea because it would probably take less space in the SD card and any backup would work on any Wii of that same region. It's probably dangerous if something happens when replacing files, but that's what BootMii is for [​IMG]

    Hmm, it's a nice idea, but I doubt that's how the NAND works. The NAND doesn't use any conventional file system that can be read by homebrew applications (yet); NAND dumping works because it copies the raw data and assumes the recipient Wii can read it, and save dumping works because it copies the saves to the SD card and uses a more conventional file system. Most of the data on the NAND, such as the system menus and IOSes, can't be copied off onto the SD card in any format other than raw...

    i have tried this already. i made a version of wanin's save manager that yanked every save from a wii and put it on the SD card. this part worked fine. the trouble i got came when installing the saves on a different wii. using wanin's save install code, saves can only be put on a wii that already has a save for that game. there needs to be a tmd for the game in question on the wii or the save installation fails. i suppose what needs to happen is the tmd should be ripped along with the original save but i havent tested this out.

    Totally Bullshit.
    You can read the filesystem and dump it in files, that's how you use Triiforce.
