Preliminary version of a work-in-progress back-up script, one touch (complete) back up. The complete is the work-in-progress.....


The script will format target ext2 partiton, where OS lives, and will leave your FAT32 untouch.
Prerequisite 1) must be adhere to, otherwise, be prepare to reflash your tablet
You may want to backup your tablet on 1st run, just in case; I have used it more than a dozen times, works fine.
WARNING WARNING WARNING...
This is a prelim version, and there is absolutely no error trapping, so you make mistake between intFlash/MMC1/MMC2, you would wipe out your working OS and be prepare to reflash.
Otherwise, this is a very useful one touch backup tool. It has been tested and works alright. Do NOT get the Warning statement discourage you, you really have to intentionally do something wrong to make it happen, I have used the script more than 20 X in the last 24 hrs, and it is really totally checked. Just follow instruction carefully for the first couple of time, then it will be a safe one touch backup

1) Prerequisite
SD boot installed
partitions ext2 MMC1 = MMC2; FAT32 partition can be anything, so a 4G and an 8 G will work together, as long as their ext2 partition is similar or same in size.
I am NOT touching your Fat32. the FAT32 can be any size.
e2fsprogs installed

2) dl script cpxxwf.txt and change it to cpxxwf.sh
xterm
gainroot
mv cpxxwf.txt to cpxxwf.sh
chmod +x cpxxwf.sh

3) Install Personal Menu

4) Personal Menu>+>Command>
Name of the menu entry - call anything you want, I like to leave it blank to save screen real estate
Command to execute - ./cpxxwf.sh
DBUS Service name - leave blank
check Run in terminal
check Run as root
Select icon - I use the floppy disk icon
click OK

From now on, you have a one touch back up between mmc1 and mmc2 which Nokia suppose to have it built-in....somehow it slipped off the crack
Clone takes about 7 min or less.

If boot from intFlash, you can freely clone between MMC1 and MMC2. However, if you are doing MMCboot, you would NOT allow to write over the active OS, i.e. the booting OS cannot be the target SD. If you build up a habbit boot from MMC1 and clone to MMC2 then you do not have to worry about anything. Or, if in doubt, just reboot from intFlash whenever you would like to backup.

Edit: Sure, this will work for N810 or N800. Just be sure to understand there N810 intSD is non-removable. As long as one partitions the ext2 external SD the same size as the internalSD on the N810, it will work.
