This is a noob question, but I have a bit of experience under my belt just so you don't have to worry too much about using "confusing" terminology.
I have rooted/ROMed many devices in the past and have heard guides talking about doing a Nandroid backup. My question is how exactly does it work? Say for example: I am on the stock ROM (rooted of course) and I do a Nandroid backup while on stock. If go to say Cyanogen and I don't like it can I just restore from my nandroid backup like I would flash any other ROM to go back to stock. And if that will get me back to stock does it also preserve all of the user data that was in that ROM when it was backed up?
Any other information about about nandroid backups would be appreciated. Thanks in advance!
From my understanding, the backup backs up all the stuff on your phone EXCEPT for what's on the SD card.
The idea is that you do a back up. Then install a new rom that you want to try out. BUt you don't like it, so you just restore the backup and woolah! your old phone is back along with all your settings, data, etc.
I'm not sure why it's called a nandroid backup, but from what I gather, you can do it with clockworkmod, just boot into recovery. And use the backup and restore option.
That was my understanding as well. I just wasn't sure on the situation with the user data (or the backup in general really). So all it takes is a nandrid backup to revert back to (rooted) stock?
A Android backup takes all the files on your device and saves them as a data.img,system.I mg,cache.I mg,user data,and recovery.img. It is also restorable through fastboot. It can also get you out of a tough spot. Say you are messing with a new theme and it causes your device not to boot up or causes unwanted problems. You can restore a backup to a time when your device was working correctly.

this is true unless you do a nandroid+android_secure backup. this also backs up your external app data

Yes you're correct. You can restore but just remember some app might have ext data in sdcard. If you don't delete it, when you restore you'll get the same as before

So if you want to restore say just your data can you just delete the images you do not wish to restore from the backup folder and it will just keep the ones you have? Or won't it work at all if you start deleting images?

i wouldnt tamper with a nandroid backup, but if you have clockwordmod recovery, that is possible. clockwordmod recovery gives you the option to restore one of those images (but only one at a time).
does a nandroid backup include your kernel?

It does! It's a compelete "snapshot" of your phone with all apps/settings etc.
Does it also backup the stuff which has been stored on the external ext2-Partition, which is mounted to enlarge the space for apps?
Same with restore of this nandroid-backup. Will it also place the backup again to the same space?
As I know there's a (symbolic) link put into /data which might get problems.

If you install another ROM with different kernel and then you want to go back to nandroid backup, does it work ?
Nandroid backups
I was wondering if the framework is saved as well. I recently updated to the ICS firmware and am wondering if I restore with a backup from the old GB firmware will that be restored as well or will it still stay on the ICS? From my understanding ICS firmware will run previous versions
will nandroid backup (made from cwm) un-brick your phone if say, you installed a custom rom via cwm and it bricked it?

Yes,It restores all data and apps nandroid backup is a mirror copy of your phone.after restoring you will get your previous stock ROM.

im not sure, i think nandroid backup will unbrick your phone as long as you can boot to recovery. atleast when i installed a roms pach it didnt fully boot, got stuck at bootanimation, no loop, just froze, then i got it back with nandroid backup
I have the latest CWM 5.xxx, but there is no Nandroid backup option.
but only those below';
- backup and restore and under it
- backup
- restore
- advanced restore
- backup to internal sd card
- advanced restore from internal sdcard
Where is NANDROID Backup?

hey guys, i want to ask about backing up phone.
i have stock rom back-ed up in clockworkmod, however now i have installed Miui.
if i backup phone again, will it erase the stock rom backup?
or will it just pop up another date to let me restore either miui or stockrom?
It'll have a different file-name (Time + Date), so it will be saved alongside any other backup you might have.
thx for the info bro.

1. IMHO, you should extract necessary settings or data and restore to your new rom. You can use AppExtractor
2. No need to delete everything before restoring
3. Your choice. There is touch version out there. Try and love it

Thanks for your reply i really appreciate it.
i was saying that if i wana go back to my stock rom (original rom) wich is not rooted can i restore it using CW?
if i flash back to my stock nandroid backup using CW my phone will not be rooted and it will restore the default samsung rom?
its just my theory though i haven't tried it yet i`m asking question like this for my future reference
Well...
Yes your device wont be rooted and will return to the stock rom.
Since the nandroid backup copies the whole partition. just like Norton Ghost does on the pc, so your phone will just go back to its exact status it was at that time.
You wont need to wipe user data/factory reset, because of the data partition being restored by CW.
Well you are asking for a recovery. How did you make a nan backup if you have no recovery?
Or you used the stock one? if you used the stock one, aren't you able to use it to restore?
Or do you want a new more powerful recovery?
As in the previous post they mentioned, use the one you like, with the most options

Hi guys, I recently rooted and I've been running Clean Rom and Clean Kernel. I'd like to try to run Viper and beastmode kernel, but I'd rather not completely reset up my phone like I had to do when I switched from stock -> cleanrom.
I've herad of using titanium backup, and I've installed it but I'm not exactly sure what it will backup and what it wont.
So my question is, if i flash to a new rom, what's the best way to backup so I have to resetup as little as possible??
Any help would be appreciated
Hi,
I've been using Titanium Backup and my experience has been great with it. Basically you want to backup all user apps and all system data. There's a function that does exactly that in Titanium Backup. I then like to copy that backup onto my computer and then I can safely flash my phone.
Here's a nice little how to video on Titanium Backup in case you haven't seen it already...
Hi
I have a couple of questions, been digging around xda and the web and found some conflicting answers...
1) Does a Nandroid backup also back up the kernel? I'm thinking about dabbling with some custom kernels, but don't want to potentially mess things up as well as have an easy way back to the stock kernel if I don't like the custom one for one reason or another.
2) What would happen if I made a Nandroid backup from recovery, did a full wipe (/data, /system, /sdcard, caches), rebooted then restored from the Nandroid backup?
I'm still pretty new to all this but I've done some reading and a wee bit of flashing & rooting on Nexus devices and the HP Touchpad. I also have an old TF101 that I'd really like to tinker with as well.
Thanks!

I don't know much about kernel but I do know that Nandroid backup backups everything exactly where the phone is.
That means if you do factory reset and restore Nandroid backup it will restore everything from the day you made the Nandroid backup.
I hope it clarifies everything.
Let me answer your questions.
1. When you do a nandroid backup, it backs up everything. Including the kernel.
2. If you nandroid backup, factory reset your device then restore your nandroid backup. Your device will return to the same state you had it previously. You will have all your content, files and settings. However if you do a backup, then factory reset and reboot, your device will be wiped of everything but it will boot up. As if the device was just turned in upon purchase. Also note, if you do a backup, then wipe your device (factory reset) you will not lose your backup.
Just note, if you ever flash a ROM, even if the developer states there is no issues. MAKE A BACKUP, sometimes things go wrong.
Happy flashing

Thanks for the quick replies!
I was a bit confused about 2) because I read somewhere that if you make a nandroid backup of a stock ROM, then install a custom ROM (non-Stock based ie CM, PA or OmniROM) you must flash the stock ROM again before you can restore the nandroid backup, or else restoring the nandroid backup will not work. Is this true?
Consider the following example, say I:
-flash TWRP on my device and root
-make nandroid of stock, rooted ROM
-wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push a non-stock custom ROM .zip file and flash the custom ROM
-decide I want to return to stock, rooted ROM after a while
-Boot into TWRP, then wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push my original stock, rooted nandroid backup to /sdcard while in reocvery
-restore nandroid backup
What would be the outcome of the above example? I'm very curious...but I'd like some advice before attempting something like this myself as I'm still kinda new to all this
BTW I'm now comfortable flashing back to stock using fastboot and the google facotry image to restore a Nexus device so I now know how to do this in case things go south. I'm just curious if this would work on a device where returning to a full stock state isn't so easy.
No you don't need to install anything to get back to the previous state. So if you had a stock rooted ROM, then backed it up. But you decided to flash, let's say. Cyanogenmod but you wished to return back to stock, you don't need to flash stock ROM, all you have to do is just wipe data and restore your backup.
And for the example.
The outcome would be, you would be resulted with a stock, rooted rom.
