is there a way for me to backup my ext2 app partition on my sdcard with a windows machine? im running cyans 4.0.2 and i love it! but i would like to be able to backup the partition 'just in case' but i only have a xp desktop. thank you!
need to backup your ext partition?
the following commands will backup/restore your ext partition to/from a folder named sdbackup in your current directory. these must be run while phone is booted, not recovery.
to backup your ext partition: adb pull /system/sd/ %CD%\sdbackup
to restore back to sdcard: adb push %CD%\sdbackup /system/sd
When you star a thread with "How..." in the title you must start this thread in Dream Q&A sub forum !

You can also use Ubuntu.
title sounds more like this thread would be instructions rather than a question.
Another way that does not require adb would be to enter the following in terminal emulator
Code:
cd system
cp -r sd /sdcard/(name of folder you wish to backup to)
Than just plug the usb into your windows box, mount the sd card, and copy the folder.

Will this allow me to move my partition to a different SD card without re-installing all my apps (via nandroid)?

I have a Kingston 8Gig Class 4 and i just bought a Transcend 8Gig Class 6 SDCard.
Can someone please tell me step by step how to backup my class 4 to and restore it to my new Class 6.
Thanks in advance!
ubuntu is the easiest way believe it or not as it is the only o that will see ur partition when u mount ur sd card. check out the wubi installer. or u can use adb.
adb remount
adb pull system/sd/app to pull the apps off, just replace pull with push when u want to put them back on the ext.
i can't recall the exact thread in this Q&A section but there was one that showed how to backup /system/sd to your sdcard then you could pull those files off on a computer and put them on the new sdcard then copy them back over to the second partition.
i think they were something like
Code:
mkdir sdcard/ext2 (the directory name doesn't matter just whatever is easiest for you to remember)
cp /system/sd /sdcard/ext2
someone correct me if something is wrong with those. then put those files on your new sdcard and go to the recovery console so you won't have to worry about any force closes with the new sdcard. make sure you do this after partitioning your new sdcard
Code:
mount /system
mount /sdcard
mkdir /system/sd
cp /sdcard/ext2 /system/sd
i think the commands were something like that. but if you have adb then the way posted above is the easiest for me.

Why don't you just use backup(for root) users application? just copy the folder it creates on your sdcard to your drive, and place into the new sdcard.
@David, I think those commands would work, but here's what I always do (and can verify it works).
Code:
rm -r /system/sd/dalvik-cache/*
rm -r /system/sd/app_s/*
cd sdcard
mkdir ext
cp /system/sd/* /sdcard/ext/
Then to push back
Code:
mount -o rw /dev/block/mmcblk0p2 /system/sd
rm -r /system/sd/*
cp /sdcard/ext/* /system/sd/
reboot
Its best to do all that in the recovery console, or adb shell when the phone is in recovery. Don't do it while the phone has booted in the ROM.
Thanks for all the help/reply...
one more question... how do i do it? do i do it in the terminal? console? or adb?
What they just gave you would be done in terminal.

I said at the bottom of my post. Recovery console is best, if you do it when your phone is actually running you could have issues.

Well yeah, ideally when the phone is in recovery...
i have a Desire and im wondering if there's a easier way to clone the sd card to another bigger. Any idea ? Cloning softwares ?
What about just dd the SD card. something like:
1. Turn off the phone
2. dd sd card to img file
3. dd img to new file
4. New sd in slot and reboot
I stupidly set my ext2 partiton to 128mb now I want to make it bigger, is it possible to do this without losing my apps?
No, back them up then re-partition the whole sd card. They are located in /system/sd/app. Search for how to setup adb and pull them or search for how to copy files in linux and that will give you the commands if you want to do it from terminal so you can copy them to /sdcard/
Don't forget to mount the /system/ as r/w, again search how to do that.
So if I have a few roms that I save with switchrom and then I decide to backup my sd to my computer.....
Then format my sd card in a different way (ie used to be ext2, now I want ext4)
And then I copy the files back onto my sdcard after the repartition....will I be able to restore those switchroms?
Because from what I have tried...it usually doesn't work...(I forget the exact error message) is there some command I am forgetting in between?
I have done this with BART, which is basically switchrom with a few modifications...
Here is what I did just the other day:
Reboot into recovery (Amon-RA)
Drop down into console
Run :
Code:
bart -s myRomName
After completed, type
Code:
reboot recovery
Then choose to Mount the SD card and copy everything over to your PC
Once completed, un-mount the SD card and then move onto partitioning...
I went from 128MB swap to 256MB swap
I went from 640MB ext2 to 1024MB ext2
After that, I upgraded to ext3... I have heard that ext2 is better, but every
time I use that format, my SD card gets corrupted in a matter of days.
(Hence the reason why I sent through this process recently.) I will "three
finger salute" the phone at times due to a hanging app, from the countless
ones that I download to try out, so this might be causing the problem.
After the upgrade, mount the SD card and copy your FAT32 section back.
Drop down into the console and type
Code:
bart -l
You should see the ROM that you just stored...
Type
Code:
bart -r myRomName
Once completed type
Code:
reboot recovery
Then go the Wipe section and Clear the Dalvik cache...
Finally reboot...
I have done this numerous times on both my and my wife's G1... I have also
done the above steps keeping the same sizes of the partitions and moving
from ext2 -> ext3 -> ext4 to give each of them a try...
Using BART will only back up the files on the ext partition, not the filesystem...
It is like a fresh install... At least that has been my experience with it...
Cool well I might use Bart then instead of switchrom since it seems to have worked for you without any hiccups.
Essentially I am doing the same process as above except with switchrom rather than bart (although i have used all 3 forms of backup in Amon Ra's Recovery)
Just wanted to make sure there wasnt some special command in console to fix something outta whack.
I figured my method would work but for some reason it doesn't like the repartitioning of the sdcard in between switchrom -s and switchrom -r
Thinking it might have been a fluke.....
Yep, I had to migrate my switchROM folder when I got my new SD Card and had no issues.

Any custom ROM has native app 2 SD, plus you can follow
http://forum.xda-developers.com/showthread.php?t=1345872
To create a special partition in your SD card to which you apps can be automatically move, plus the swap space that will give you more free memory.
There are two good guides about custom roms:
http://forum.xda-developers.com/showthread.php?t=1333865
http://forum.xda-developers.com/showthread.php?t=1222348
If you are new to this, it will take some time get used to these guides, tools, etc. But there are lots of fun on testing custom ROMs, overclock, benchmarks, different skins, launchers, etc.
A good start is the toolbox, from puppet13th post:
http://forum.xda-developers.com/showthread.php?t=1117100
It is text only, different from SuperOneClick, a really great tool too, but toolbox can root your phone, install some modules (overclock, cypress / synaptics dual touch), and most important, the dual recovery: freexperia (or xrecovery... I don't remember) plus clockworkmod. Some ROMs are designed for the first one, but most recent ones are for CWM.
how do you partition sd card? i use to be able to do that until i formatted my sd card...now i forgot how to!

I did this yesterday, following this thread:
http://forum.xda-developers.com/showthread.php?t=1345872
I would prefer another way to repartition my SD, as Linux GPartED, that can easily resize partitions and add new ones. But I couldn't find the requirements for that and had problems a couple of months ago, when I tried to replace my SD and it was reformatted (don't know why) automatically, with no warning.
So I almost followed the thread:
1) backed up all my files (I just mounted SD and copied the files, as I didn't had sd-ext yet)
2) reboot into clockworkmod. I backup here is STRONGLY RECOMMENDED!
3) mounted /system & /data, and unmount /sdcard
4) copied sdparted.txt to /sbin/sdparted (already rooted, otherwise it would not work)
adb push sdparted.txt /sbin/sdparted
adb shell chmod 755 /sbin/sdparted
5) As I was in a different ROM, MiniCM7 2.1.6, I didn't have parted, required by sdparted.
So I copied from GingerDX v21
adb push parted /usr/xbin/parted
adb shell chmod 755 /usr/xbin/sdparted
But if your ROM already have parted, you can skip this.
6) Now just run sdparted as mentioned in MarJar thread. I have a 8 GB SD, and I choose 512 MB for sd-ext and 256 MB for swap, leaving more than 7 GB for files. So mine was:
adb shell
sdparted -es 512M -ss 256M -efs ext4
(someone, somewhere, mentioned that ext4 would be faster. I saw some benchmarks for Linux telling the opposite... But ext4 jas journaling, so it should be safer)
Now you have a partitioned SD.
7) Copy userinit.tx from the thread to /sd-ext/userinit.sh. It will be automatically executed on startup and mount the enable swap:
adb push userinit.txt /sd-ext/userinit.sh
adb shell chmod 755 /sd-ext/userinit.sh
8) Now I would recommend, if you have installed your apps to your ROM, to mount the SD again and copy the files back to the SD. You can do it in clockworkmod, menu Partitions or something like that, choosing Mount SD Card.
I didn't, so when I rebooted the phone, the "Apps" (or whatever remained fromthem in /data) were move to /sd-ext automatically. But any previous ROM, as mine also, would keep files in SD. The result was the nothing was working. So I copied the files back to SD card and restored the backup I took in step 2 (that saved me ).
But if you restore the files back to SD before rebooting, I think you would be fine.
It worked gracefully for me after restoring the backup.
9) Reboot and enjoy.

you need to push to /data/media/0
/sdcard is just a symlink from /data/media/0.
...if you use twrp you can also use adb sideload:
