Back Up Nand Feature

Everytime I go to use backup nand it goes really slow and then freezes and when I say Slow its been over an hour then it froze. This has happened twice.

Have you tried using a different SD card?

It's probably because your SD card is too small. You need atleast a 1 GB card because your NAND will take up around 528 MBs.

The sd size was fine but I changed SD cards as that was the problem. So thanks diffikolt problem solved.

No problem at all. :)

Again, glad I could help.

after copying the nand.bin backup to a computer and reformatting the card again for normal use,
is all i have to do to restore the backup at a later time to reformat the card in fat32, label it bootmiibackup and put that nand.bin on it and the \bootmii\ files?

Do you have 2 SD cards? Assuming so, your best bet is to just leave the Bootmii files on one. If you need to restore NAND, go to that feature in Bootmii and before you click it, switch out the SD card with the one that has NAND.bin. :)

I just have 1 SD-card available for Wii usage. For homebrew, I have a lot of big files on it (huge data files for scummvm for example). There is no room to keep the nand.bin on it. So I'm really wondering if I can just copy it to a PC and restore it later if necessarry.

I don't see why not. That's what I did. Actually burned the nand.bin file along with the bootmii directory to a cd to store away in case of emergencies.

Now if it copied the blocks bit for bit to the SD card rather than as a file on the fat32 FS (like I originally thought was going to be when it wanted to format the card), it'd be a different story. But looks like it's ok to save the nand.bin somewhere and bring it back later when needed.
