[Q] What is all about Nandroid backup? - Android Q&A, Help & Troubleshooting

I have used android (my Neo V) for month, I flash few ROM with respect and responsibility.
I always backup my phone for the worst case but still now I not fully understand Nandroid backup.
Does it backup full my kernel and baseband beside everything that show up in the script?
(Like /system, /data, /cache, /sd-ext ....)
Thank you very much.

It backs up all partiotions on your phone
the system the data the cache recovery boot (add if i forgot sth)
if i remember right it does not backup your internal sd but anyway the internal sd is not affected by installing a rom

Kernel will not be included in the backup.

Thats not entirely true, all the recoveries I have used have had an option to backup the boot partition...

of course the kernel is included
for instance
you run stock gingerbread with custom kernel
you want to try cyanogenmod
you make a nandroid backup
afterwards you flash cm and after a while you want to get back to stock rom
you restore your backup and afterwards its exactly the same rom on your phone as it was when you made your backup

Kernel IS included in boot.img

Thanks for correcting me

On my LG-P990 it does not backup the (internal) /sdcard partition.
When I first did not know about this I once formatted it which extinguished my save games and pictures

[Q] How to safely test MIUI and revert?

So MIUI is available and I want to try it.
But I will likely want to revert to my phone as it is now.
Right now, I am running 2.3.4, baseband I9100XXKI1, kernel 2.6.35.7-I9100XWKI4, build XWKI4. It is rooted, has Superuser and ClockWorkMod, no Root Manager. I have no physical SD card.
How do I get MIUI on to my phone?
What, if anything, will that process delete?
What should I backup and how to restore?
ie. If I do a backup in ClockworkMod, is that effectively backing up the whole phone or just the kernel and ROM? ie. Is restoring a ClockworkMod backup enough to restore the phone to its pre-MIUI state?
Install rom manager
Backup your current rom. It backs up everything
Download miui from the miui website. You can also download it directly from rom manager.
Boot into recovery using vol up, home and pwr button and flash the rom. You will have to reinstall rom manager in miui.
Play with miui
Restore your previous rom from rom manager.

Just make backup and if you don't like miui, then you just restore. And everything will be back as you had before miui. Don't forget to wipe data and cache before flashing miui. Clear Dalviks cache aswell!

I recall being told on this forum that ROM Manager doesn't work on this handset.
can I clarify...ROM Manager basically just invokes the clockwork mod recovery, right?
So a backup in this way would backup absolutely everything, including the contents of the internal sd card?

Where should I be placing the MIUI .zip? On /sdcard?
Similar question re: backup - does ClockworkMod backup include the contents of /sdcard? Or is that not included because, technically, that is regarded a physical SD card?

Only backup your system, app and setting. Don't backup all your data on sd card
You can copy zip file to sd, go to CWM recovery menu, wipe all then choose flash zip file from sd card

I think what he might be getting at is can he place the zip on the internal storage of the device, and flash it? As it seems he doesn't own a SD card.
Just a heads-up: I tested MIUI on Friday, after making a full Nandroid backup of my VR3.0 with CMW.
When I did a restore of my VR backup afterwards, a lot of apps were force-closing, and even fixing permissions or wiping cache and Dalvik cache did not help.
What did work was a flash of CM7, allowing it to boot once, and then restore VR again (with a full wipe of course). Everything is running fine again now. I suppose this has something to do with the CWM recovery version included in the kernels (my VR had a 4.x version, CM was 5.x).

[Q] Wiping phone (for real this time)

HI,
I've recently rooted my phone, installed new ROMs/Kernels. Prior to installing the ROM, I wiped my storage, my cache, my dalvik cache, etc. However, when I was looking around my folders, I noticed files from pre-wipe - in other words, it didnt really wipe my phone out. Now obviously I dont want dead applications taking up space - how can I properly wipe the phone before installing a new ROM?
Thanks !
Try to do a factory wiped from the phone. I think that does the trick.

you can use SUPER WIPE script from Android Revolution HD. This will wipe everything on your phone internal SD-card. Don't forget to backup. You can find it here >> http://forum.xda-developers.com/showthread.php?t=1797334
you can also use this tool. I guess it is the same as revolutionHD from above member posted whereas you have different options/stages of wiping the phone.
You can either use super or mega wipe (leaves you without anything on the phone!! so be careful)
Thanks guys - I used superwipe (from Android HD). Now running a clean system, without all the residual crap from applications (that took up 4GB of space!).
Will this super wipe android HD also wipe the efs folder and nandroid backup or are these in a separate partitions and remain untouched?
Thanks

As what I have read, it wipes whatever a full wipe will and should not wipe nandroid backups.. However I have not used it before and it's better to wait for confirmation from someone who used it.

I can confirm it doesn't wipe the efs partition - as that could well and truly screw up your phone, especially if you didn't have a backup stores somewhere.
Superwipe wipes your data, cache, preloaded and system partitions - pretty much your entire internal sd card, if I'm not mistaken. I really like the megawipe tool that's been mentioned here too. You should give that a try when next updating.
As to the backups - I've no idea. It all depends on where the backups are created. I think CWM backups are created in data partition which would mean that if you did super wipe they'd also be deleted.
I never back up though so I can't be 100% sure as I've never needed it.

Data lost after a nandroid backup restoration

Hi there. Yesterday, before flashing leaked 4.2.1 ROM, I did a nandroid backup to my external microSD card using Philz Touch Recovery v. 4.63. The process of backing up was successful.
The problem came when I restored the backup. (Before restoration, I had to reinstall the PhilZ Touch recovery and, from it, I did format cache, format system and format data). I recovered my XXEMA2 ROM with all the apps and configurations I had before, BUT there is no trace of the pictures I had in the internal memory or the files I downloaded.
I tried to repeat the process, but I got the same result.
Does anybody know a solution for this?
Thanks in advance.

Nandroid only backs up your ROM, recovery, apps, app data, etc. and not the data stored in your internal storage.

Ooopppps, I thought it makes a complete image of the phone! (for example, on many websites it's compared with Norton Ghost for PC). Good to know for the next time...
Thank you for the information, Oomahey!

After going back from 4.2.1 to 4.1.2 you'll have your whole Internal Memory in a folder "0". Find it on your Internal Memory. All your data and files should be there. Just transfer them from folder 0 to root of Internal Memory and all will be like before flashing 4.2.1

I seem to be blind! I was looking for the "thanks" button, but I didn't found it (I thought that maybe it didn't appear since I was surfing from my mobile). That's why I said "thanks" texting.
EDIT: I was not blind. In the default version of the forum (the classic one) that appears on my Opera Mobile there is not "thanks" button. You need to change manually the versión to 2010 one or higher.

I do have the "0" folder with the old (sub)folders, but all of them are empty :crying:
Maybe it was not a good idea to do format cache/system/data before restoring the nandroid backup... As I thought all data were preserved in the backup, I prefered to delete any trace of 4.2.1 ROM .

Well, that might be the problem. I had also restoring 4.1.2 backup after trying 4.2.1 FW but I didn't do wiping or formating - I just restored backup and there was that 0 folder and all files from Internal were there.

[Sola]Noob Questions about BackUp when flashing

Hey,
I wanted to flash JB eXperience™ v2 on my Sola with the locked bootloader. (http://forum.xda-developers.com/showpost.php?p=38682504&postcount=173) But I want also to still have my datas and apps etc. So I think I'l have to make a backup and here we go to my questions:
Is the Sony BackUp App enough for that or will this be deleted?
Which methods are the best to backup?, I Can't use TitaniumBackup because I swapped the internal SD Card.
Is the CWM Backup and Restore thing enought or will it be also deleted? Do I have to install it again?
Thank you :good:

The CWM backup is more than enough it backup all ur ROMs Settings,Apks all
I m not earning money by helping you so if u think I gave my time so pls press thanx button
The CWM backup is a Nandroid backup which makes an image of your phone when you backup it.
It's the best backup.
By the way, you should know that only restore /data/ partition after flashing the ROM.
And wipe Dalvik Cache after restoring because the /data/ partition has /data/dalvilcache, so it might interfere with your new ROM (since that dalvik cache is of a previous date when you backed up and the ROM is just flashed).
The /data/ partition will restore everything, your homescreen settings and widgets too, Don't worry, That's how I did it and it's fine for me

CWM noob question

If I restore back up I made with CWM with it will it flash Rom too?
I mean let's say I have stock Samsung Rom then I flash the cm back will it be like flashing new cm Rom but with my apps and settings already?
Restoring android backup take your phone exactly at the moment the backup was done. Rom, kernel, apps, data, everything.

A Nandroid backup takes images of your partitions.
If you want to restore a previously made Nandroid backup, enter Recovery Mode select Restore. Everything should go back to how it was when you made the backup.
If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache.
Downloaded apps, apps and OS settings, contacts, messages are backed up in data (/data)
boot has the initrd.gz and zImage.
system has the system files (/system)
cache has the cache (/cache).
SD-ext has the ext partition
