I have an SD card with 3 partitions: fat32(7gB)/ext4(488mB)/swap(91mB). not sure what order I created them in, and not sure if that matters.
when I do a nandroid backup, is it also backing up my ext4 partition where my apps2sd apps are kept? I want to be able to use nandroid to swap between many different ROMS, but still have all my settings saved per ROM. And hopefully apps as well, whether it be by the nandroid restore or (and im not even sure if it works this next way im describing) by different ROMS being able to see the apps in apps2sd and use them?
Like I said, Im not sure how apps storage/location actually works. If I install apps on the sd card, and I put an upgraded or even a different custom ROM on, does the system see the apps on the new ROM? Or are we also supposed to wipe ext partitions as well?
Can someone let me know what "wiping" data and/or cache actually does? IS there a basic phone architecture doc I can read to see what data / cache actually is used for?
Wiping refers to the internal memory of the device. Not the SD.
By wiping you remove all settings and software installed on the device itself.
If you boot after a wipe, you will have to re-enter your google account information and wait for the sync to complete.
If you have apps2sd, (most of) your apps will be on the ext partition on your SD card. Those don't get deleted when you wipe. If you have go from 1 apps2sd capable rom to another, your apps will still be there. And the apps that store settings on the SD will have their settings saved too (only one I know of is gem-miner).

I recommend using a more complete back-up and restore tool like BART or Switchrom. Do a search for BART on the Dream Development forum and you'll find everything you need. It's built in to the latest RA recovery images as well and works great.
I have my phone set up the way I want it with all apps email settings etc.
My question is which backup should i use NANDORID + EXT or NANDROID.
I would like to install other roms for testing etc but i want the option to return to my preferred setup without having to install all my apps and settings again. I store my apps on the phone not sd card if that makes a diff???? Any help would be great. Ive searched the boards and google and still cant come up with a clear definition of the difference between the two... Ive only been able to rule out a BART backup.
Thanks

the +ext part errors out for me.
Plain old nandroid seems to work great.
I've done it and restored it many times. The phone seems 100% normal after a restore. All apps, settings, icons, scenes ,and everything.
The ext portion of that backup applies when you have a partitioned SD card (1 part vfat, 1 part ext2/3), and you are storing stuff in the ext partition.
I am under the impression that apps2sd works best if apps are stored in a file system with owner/group attributes, because apps are supposed to be compartmentalized by unique user IDs. If you merely copied apps to the SD card in the regular (fat/vfat) partition, that info would get lost.
Presumably, apps can be run directly off the SD card if they are in a mounted ext filesystem.
I don't know this for a fact; I am guessing. But I think it's a good guess
Don't partition a SD card with anything on it you value, BTW.

What is the best way to move from a SD based CM7 to a emmc CM7 and not loose any apps or data? I've been running off the SD card for several weeks and am ready to move to the flash based setup but don't want to loose any data or apps. I may also want to be able to dual boot into the Nook 1.2. Currently running CM7 41, OC Kernel 04/04/11, and dualboot menu all off the SD card.
Thanks,
jmak
+1. Little help?
Thanks!
titanium backup your apps/data, then install fresh copy on emmc, then restore all
I thought about doing the reverse, emmc to sd but that thought went away after a few minutes

How do you use titanium backup to do the restore since the backup is stored on the original SD card that was used to boot CM7? Do you have to copy the backup files to another card to do the restore?

yes,
-do the backup,
-copy the sdcard/TitaniumBackup folder to your computer (via adb/cifs-wifi/dropbox/ESFileExplorer/whatever)
-install your prefered ROM
-copy to sdcard/TitaniumBackup from your computer's copy
-batch restore (i'd buy titanium pro if you have many apps, if not, it will ask to confirm restoring one by one)
Hello,
I wonder if anyone know... What happens when let's say i have 9gb of data on my s2 and i want to backup it with nandroid? It should be possible to do this to sd card, but what if some apps are on phone and some on sd card? How backup then?
If i upgrade to a newer custom built rom, i them try to backup, wouldn't it restore the older backed up firmware? Or just apps and settings, but not rom itself?
Thank you,
Tomas
no one? did no one fill their phone and tried to backup? maybe there is a solution to backup to a computer?

Nandroid backups are an image of
/system
/data
/dbdata
(on CF-Root, not sure about original CWM) it also includes .android_secure, which is SD-stored apps.
I don't understand what you are asking.
If there is not enough space you obviously have to delete something.
BTW: data-partition is around 2,1GB and system-partition 500MB, so there is no way a single backup can use 9GB
Maybe I am not being very clear, sorry about that
Coming from an Iphone, i am looking for a total phone backup solution. Itunes backs up literally everything - your apps, music, photos etc. It's filled probably with 20gb of different data.
Question is if I have my phone filled with games, different apps which make let's say 10 gb (not that much counting in that one game may be up to 1 gb), so how do i backup this? To SD card?
What if I have 20gb of data , 10 of which are on phone, 10 on sd card, in this case i wouldn't be able to backup everything?
One more technical question about rom upgrades. Currently i installed Villain Rom and have a backup made with nandroid. When i upgrade to a newer Villain Rom 1.5 or whatever comes out and I do the restore, i suppose it will restore 1.4 rom version with it's all apps and settings?
In this case, how do i backup only accounts, contacts, sms , apps, photogallery but not rom itself?
Sorry for all those questions, but i'm reading the forum all over, and there's still hundreds of questions i'm looking to find answers, so that i could comfortably migrate from iphone to galaxy..

Regarding restoring only apps/accounts/etc but not the rom iteself, within cwm, in backup and restore, chhoose advanced restore and the restore data.
Im not certain whether it restores gallery or sms.i sync my photos via dropbox, and backup my texts seperately.

So there is no unified backup solution for android? You would have to back up everything separately ?

It's fairly simple:
Nandroid for your ROM and user data that is on the PHONE and /data partition
For the /sdcard and /sdcard/external_sd, that's up to you to sort out... Perhaps back up the contents by connecting to your PC? Then copy the contents of the SD? That way you have your nandroid backup stored on the computer just in case
so then in case something goes wrong, i restore with nandroid and manually copy contents from PC and ALL of my phone's data (software, contacts, gallery etc) will be there?

Well, now you have a phone that doesn´t hide everything from the user it shouldn´t be that hard to make a backup.
There are basically 4 interesting partitions on the phone:
system (about 500MB) - This holds more or less the whole Firmware. While it is technically just a partition on the flash-memory, it is used like a ROM in normal usage, so the only situation where something will be written on this partition is a firmware-upgrade.
data (about 2GB)- This partition holds all user-installed apps and their settings.
sdcard (about 12GB) - This is not really a sdcard. Instead it is a part of the internal memory, you can use it for example for media, documents, images etc., whatever you like. This partition can be accessed on your computer as a regular USB-storage, and you can do a backup of it the way you like, either simply copying everything, or using a backup-solution of your choice.
external_sd (optional) - This is the micro-sd-card you can put in your phone. Obviously you can use it for anything you like. This partition is also accessible as a USB-storage or you can use a simple USB card-reader to access it on your computer.
Usually all your applications and settings will be stored in the /data/-partition.
If you choose the Move-to-SD option in the application-manager, some parts of the application will be moved to the (internal) /sdcard/-partition, but all the user-data/settings still remain on the /data/-partition.
So the maximum space you need to backup all your settings and apps is under 3GB.
Now to the possibilities of a backup, and the importance of the different things.
A nandroid-backup will basically make an image of the /system/ and /data/ partitions (also a bit more, but that´s not really important).
Usually it will use the /sdcard/-partition, which actually is still in your phone.
If you restore a Nandroid-Backup your System will be in the exact state before the backup, including all applications with their settings (which also means contacts, e-mails, sms etc).
Obviously everything that has changed after the backup will be lost.
A restore well also restore the complete firmware from the backup.
A backup from Nandroid can only be restored on the same phone, with the same partitions.
The second possibility to make backups would be TitaniumBackup.
This program will store all your installed applications and their data.
Default it will store it on the internal /sdcard/, but it is probably more useful to change the path to the external_sd.
Everything in Android is an application, so this will also save all your settings.
During a restore TitaniumBackup simply reinstalls your applications and then restores their settings.
TitaniumBackup can restore your applications with any Firmware, and in theory even on other phones (it may not work with special System-apps but it surely works with most "user-apps")
So Clockworkmod is great if you want to play around with different firmwares, especially Custom ROMs.
You can install different ROMs, make a backup and very easy and fast switch between them.
For a "regular" backup TitaniumBackup is maybe the better choice, it can backup all your settings and applications and for example if a Firmware-update goes wrong simply restore anything.
There is no real need to backup the /system/-partition anyway, you can simply download the Firmware and flash it, there is no user-data on this partition.
sdcard and external_sd usually only contains media, which you probably have somewhere on your PC anyway, so there is no real need for a backup, maybe for the pictures and videos you make with your phone, but again you should copy this on your PC regularly anyway. And if you want you can easily copy everything on it as well.
What if I have 20gb of data , 10 of which are on phone, 10 on sd card, in this case i wouldn't be able to backup everything?

Apps can´t be several GB in size on Android. Normally you have only around 2GB for Apps, if you use the App2SD-feature it can be expanded a bit.
If applications need a lot of data, for example like navigation-programs or games, they will download this on the first start and store this on the /sdcard/-partition.
As I said, you can access this easily like a removable drive and copy everything you like.
It isn´t also that important to make a backup of this, as it can be downloaded again anytime, and if something goes wrong it usually will mess up your system and don´t influence the data-partition anyway (well as long as you don´t repartition the whole memory)
Thank you, that does explain a lot!
I connected my S2, but i can't see to find any installed apps browsing through USB, or i shouldn't be seeing that?

No, they are stored in /data
You back that up using nandroid, then you restore it via nandroid and they will be there. What you see on your PC via USB is the "internal SD".
Understood, thank you. Things getting more clear after a week of reading and using the phone ))

No, you see the (internal) /sdcard/ partition and (if present) the /external_sd/ (the MicroSD-card you have in your phone)
To simply backup your applications, the easiest way is TitaniumBackup.
This will store the .apk and settings for each up in a folder of your choice (on /sdcard/ or /external_sd/, as you usually have no direct access to the other partitions)
You can copy this folder on your PC, or even in the TitaniumBackup-folder of another phone and use it there.
There are several advantages using TitaniumBackup to save your Apps over CWM-recovery. You can use it with the enabled phone for example, and also just restore individual Apps, if you like.
Hey there. I have what I bet is a silly question for most here. Anyhow, here goes:
I have my user apps and data backed up with Titanium Backup. Am on stock Lollipop, but will flash CM12 eventually. As it requires a data wipe, my question is how to "save" backed up data in TIBackup so that I can restore everything I need after flashing?
Is everything stored in some specific file/folder that I need to copy to my PC and copy it back on my SD card after flashing CM? Or is it something else?
Thanks in advance.

Oh crap, it's the whole TitaniumBackup folder isn't it? I was hoping it was all compressed in one file, but... Oh well. Thank you for the info, case closed.
