Correct way to flash an MTD partition using mtd-utils

[Matthew Stanger]

Hi all,

I'm hoping someone would be able to tell me the correct way to backup
a mtd partition. Right now I'm cleaning up some code that would run
nanddump and pipe it to ubiformat, to dump a RFS from one primary
partition to an identically sized backup partition. The overlaying
filesystem being UBIFS. The issue is if the backup partition has an
extra badblock, than the source, then there isn't enough room. I'm not
an expert in this space so I'm hoping someone can clarify what the
correct way is to do this; I'm pretty sure this method isn't right? Is
using 'mkfs.ubifs' to copy the RFS at the UBIFS layer they way to go
and then restore it with 'ubinize'? Is there a better, faster way?
Thanks for any tips.

Cheers,
Matt
