Zbackup For Pdaxii13

[Meanie]

Hey Meanie,

Ok, I got pdaxii13 5.3.2 going and tried your zbackup 0.16. Well looks like your fix worked, the initrd.bin backup worked perfectly.  I'm still trying stuff, but no bugs so far.

This is great!

I will add some more bug fixes for C3100/C3200 in zbackup 0.17 then zbackup will work for all models

does the following work:

mkdir -p /mnt/nand
mount -t jffs2 /dev/mtdblock2 /mnt/nand

Yes, it does (as to be expected). Actually, the mtdblock-devices do represent the NAND-memory, don't they? And as far as I have seen "/dev/root" is just a symlink to "/dev/mtdblock2" which is mounted as "/".

I'm not sure what the other mtdblock-devices are, though. 0 and 1 both have a size of 7MB on my system, so I guess that the boot block must be somewhere there. This, of course, would also have to be included in a backup.

Would it be a good idea to "dd" the whole nand, i.e. mtdblock0-3, into an initrd-file and just flash them back on restore?

mtdblock0 is kernel?
mtdblock1 is emergency rootfs
mtdblock2 is rootfs
mtdblock3 is home

initrd.bin only contains rootfs and a tarred up home is inside the /root directory of rootfs
