[Q] nandroid backup

If i perform a nandroid back up of current rom and then flash a new rom , then discover I dont want rom i just flashed. Can I wipe and install a 3rd rom without backup since i backed up original rom and thus have a restore point? Not that I mind back ups but they hog alot of space on sd card.Thanks

Yes you can.

Yes you can, I actually keep a sense rom in nandroid just for the purpose of updating my pri and prl. You can go in to your nandroid folder and rename your nandroids to mor memorable names so there easier to indentify, just dont use spaces in the folder name.
You dont even need to wipe to switch your rom from nandroid back up to nandroid back up, just restore to the one you want. at most youll have to wipe the dalvik.

cool! thanks for the help.

When would you backup a rom?

For me,I backup my rom before update a rom and after update it.
When would you make a backup??

Before and after too. if all goes well i remove old backup but sometimes i keep, on Froyobread now but i still have a Floyo backup to go back to if i ever want.

Ya,I still keep a backup of MiniCM,and Hackdroid(I'm now using Floyo)

I often do a full wipe before and after flashing updates or new ROM's. So I do a backup when all my app's/settings are applied and I keep a copy of the SDcard with the backup to restore in case I face any problem...

oh I see,backup is really important.

Noob question on CWM backups

Hi all,
A question regarding backups:
I am currently on CM7 MIUI.US and am thinking of switching back to GB roms. If I do a backup on CWM now, and flashing stock GB + roms over, and if I so happen to not like the ROM and wishes to go back to MIUI, I can simply do a restore on my old backup is that correct?
Now backing up, do I need to do a factory reset? I am okay with cache + dalvik wipes, but factory resetting will reset all the customisation done on my MIUI rom and it is a nasty thing to do all over again (dragging and sorting all the apps into respective folders )
And I would have to use TiB to do all the restoration of my apps! and I would have to choose what apps to backup etc etc..
Thanks for any answers xda folks!

well you can maker a nandroid backup in CWM this is like an ISO image of the whole ROM, whether you will have issues restoring it on GB roms i dont know.
You could make a backup using the MIUI backup (which backs up settings and screen layouts and so on) but this would only be able to restore on MIUI ROM (if you decide to go back)
I would make a backup using MIUI, and make a backup using Ti Backup (if you have the paid version its all automated, No need to press DONE after each app has backed up)
Hope this helps.
EDIT: you could make a nandroid backup too, what the hell, if your flashing anyway, Im just not 100% sure it will work.

Yea i was asking if backing up nandroid will help when i want to revert.. But thanks for the heads up on the miui backup! And yeah I have tib pro so restoring isn't a pain, the tough part is the choosing of the apps to restore..

Well restoring a nandroid backup of a MIUI ROM and restoring it on a Different ROM MAY cause problems (ive never tried this)
Restore all your apps !! if you need to choose you obviously have too many and dont use them.
Delete the junk, Keep the good save yourself some space too !!
(im also an app collector lol)

There are those files from like 162939594 years ago that I use TiB to backup and never restored

[Q]Nandroid Backup

Hello guys,
I bought SGS1 a while ago and changed some roms it was annoying losing my apps then my friend told me to use titanium backup it was more annyong cuz i had to backup one program at a time
then i heard about Nandroid Backup , so my question is:
if i change ROM lets say from MIUI to Darky or something and i used Nandroid Backup, all my apps will be there after i restore?

Your phone will shift back exactly where it was when you nandroid backed up ! And any progress from their will be lost !

So if I change rom from miui to brand new one and then i restore it will go back to miui? or it will just put my apps from miui on the brand new rom?

Its backup whole rom with apps...tge best possible solution is u have to use titanium backup pro it make a complete backup of apps....i thinkn u r using some free version pf titanium thats why i makes problem.

Titanium Backup offers the option to backup all your apps at the same time, in case you didn't know. This may be only for the paid version though, I'm not sure. But considering it's the most useful app I've come across, it's definitely worth the money.

Actually if you try to restore a nandroid backup after switching to cm7/miui, your phone simply wont work as the file systems are completely different.
To go back to a Samsung ROM from miui you would need to flash a stock Samsung ROM via odin, and THEN restore the nandroid.
Anyway, beyond that remember the following...
Titanium backs up apps and app data, use after changing ROMs to regain apps.
Nandroid takes a snapshot of the entire ROM, use in case of problems to repair your phone.

Correctly said rschenck!!
Basically if you are on CM7 and want to give a try to MIUI just make a NANDROID backup for full ROM backup and try MIUI ,if you don't like it then flash back CM7 first and then restore the NANDROID backup!!
when it comes to Titaniuim backup , it backs up your app data,freezes them and the apps you want (only in pro version) on any ROM and restore back after flashing any other ROM, if you are on free version then you must select manually which apps to backup that's a pain in the ass !!
Use these according to your requirements....and dont ever restore one rom's nandroid with another as the Kernels,Filesystems,Modems,Bootloaders are entirely different and that could mess up your phone !!
i would prefer NANDROID over Titanuim !!

Thanks guys for this wonderful explanation...just one more query:
I'm currently using samsung Stock rom, CF root kernel, with lagfix(ext4), and some "framework" tweaks..and am thinking of trying CyanogenMod. So if i do a Nandroid backup now, and later decide to come back from cyanogenmod, can i just use Odin to get to ANY Stock rom so that the partitions, file systems, modem etc get back to a similar old format, OR do i need this exact Stock rom version, Kernel, lagfix etc before i can restore the nandroid?
is "kernel" included in a Nandroid backup? also, are Types of filesystems included (or "Lagfix" has to be repeated)?

NANDroid backup

what is a nandroid? how do you perform a NANDroid backup of your current ROM? im going to cm7 stable from kj1. just wondering cause it says in the steps to install cm7. thanks..sorry for the noob ques..

its making a complete backup of ur current rom settings,apps and all. with i897 gingerbread roms i dont think u can restore a nandroid backup. but u would normally do a backup in recovery with cwm.

yes, nandroid on i897 ginger roms do not work.
but the procedure would be to make a backup. then if you flash a different rom from what the backup was made from you would have to flash the rom back that was backed up THEN restore the nandroid and it will be like you never flashed away from that rom.
DO NOT EVER restore a nandroid to a set up it was not backed up on, it will bootloop.

can you expound on that please...hahaha..sorry im reading it over and over..just need to clarify..what you mean? thanks btw guys for the reply..so basically nandroid backs up your rom..cause just the name sounded confusing..i mean why name it nandroid when they can just say in the intructions before flashing a rom to just "back up" your rom..haha..i thought nandroid was something else..cause i heard other people saying something about efs or whatever and backing it up but i dont even know what that is especially..thanks though for replies..got it..

Say you back up your current ROM, then flash another. You can't just restore ROM A onto ROM b. You have to flash back to ROM A and THEN restore the nandroid and it will be like you never flashed ROM b. All of you settings and everything will be intact.
Efs is totally different, that is a partition that contains your phones individual data, it's imei which you have to manually backup it's not included in a nandroid.

Components backed up by NANDroid
Which of these components does NANDROID back up?
- bootloaders?
- kernel?
- system apps and other apps?
- modems?
- other parts of the OS?
Thanks for sharing the knowledge.

The firmware and system settings.
No kernel
No bootloader
No modem

Kindly clarify this please, i want to backup my stock rom before going custom.
So inorder to do a complete backup, we need to do a nandroid backup and also backup imei separately?? and then restore both of them when i flash back to stock??

They are two separate issues, really, but you are correct that you should back up both.
Nandroid lets you go back to a previous state, as long as you flash back to the correct ROM before you restore it. It will not let you restore data to your new installation, though. If you want to restore your applications in your new ROM, you can download Titanium Backup from the market which will let you batch save your applications now and restore them on your new ROM (It can also save and restore system data, but don't restore system data between ROMs, it causes all sorts of weird issues).
Backing up your EFS folder is something you should do, but hopefully will never have to restore. Your EFS folder contains information about your phone and should never actually get touched in any way when flashing ROMs. However, things go wrong and sometimes this folder ends up getting corrupted for whatever reason, which can lead to a corrupt IMEI code and no service. If this were to happen, you would restore you EFS from backup. I think it's safe to say most of us have never had to actually do this, but better safe than sorry. You can do a search for backing it up and find several threads about it.
Happy flashing!

lol...I was about to do nandroid backup! These post wre real helpful...thank you!

See this thread in the Development Forum for Corn Kernel... It has a working nandroid. BTW, that kernel is for i897 Gingerbread Roms.

When I run a nandroid backup I see it processing these:
- boot image
- recovery image
- system
- data
- datadata
- .android_secure
- cache
- sd-ext
Can anyone explain some of these terms to me? I am pretty new to all this.

This thread has all the goodies defined pretty well http://forum.xda-developers.com/showthread.php?t=1093062

You will need to first get it on the same modded ROM and then flash the backup. They will then be identicle

Hello,
This is the thread I was looking for. It just tackles top backup/restore issues I want to be positive of before tinkering around.
Now, what app is capable of doing a nandroid backup, if any? RomManager?
If a nandroid backup consists of the firmware and system settings but no kernel, bootloader or modem, how are these three backed up then?
My goal is making a stock unrooted (if possible) backup.
A concerning restoring, from this thread I understand that the restore process is composed of:
1st restore ROM A (which?)
2nd restore nandroid (which?)
3rd restore data/apps (Titanium is able to)
4th restore EFS folder (how?)
Please, correct/suggest. I appreciate.
Greetings,

First of all, you have revived an old thread with now false information. A nandroid does include modem and kernel. Bootloaders can't be backed up, and there really wouldn't be a point in that. No app can do a backup, and please don't use ROM manager; it's obsolete. As for your steps: You probably only need to flash a ROM first if the partition table is being changed. Meaning you can't restore a Samsung ROM over an AOSP ROM. You won't need to use titanium backup because you will have restored the phone to the exact state it was when you took the backup. Meaning there won't be anything to restore. Efs? Don't touch it, we never will be deleting it.

Modems and kernels ARE NOT backed up in a Nandroid...

Hello,
@korockinout13: I don't think I'm providing false info. Actually, i've been gathering from the thread. I think there's some disagreement on what a nandroid backup really backs up from the views expressed in the thread. Plus, it's pure netiquette not opening new threads for a topic already started somewhere else in a forum. It's power ecology. No hard feelings, though.
Thank you and b-eock for your replies. I think I'd rather use cwm instead.
My goal is still the same: making a stock unrooted (if possible) backup as there are no roms available for my brand new Mini:
pda S5570XWKQG
phone S5570XWKQ5
csc S5570YOGKQ3
android version 2.3.4
Kernel 2.6.35
Thank you both!

Someone told me about the modem part, so I'm not really sure about that. But if it doesn't backup the kernel, why does restoring a nandroid put you back on the kernel you had previously (i.e. Glitch)?
