    [HOW TO] Perform a Full System Backup unrooted Android 4.0, 4.1 or 4.2 device

    I ran across this at XDA (Thanks copkay!) and figured I would make a guide of it here for others to find:

    There is a feature of ICS & JellyBean that allows full system backups via ADB. You will need to have your android device unlocked to perform this. If you do not have your PIN/Password/Pattern, it will not work.

    This has been tested on both rooted and unrooted TF101 tablets and will work for unrooted tablets.

    BACKUP YOUR DATA

    First, you must go to Settings - Developer Options - USB Debugging and enable this option. This enables your device to work with ADB

    You may be asking what is ADB. This is Android Debug Bridge. It is a way to connect to your tablet to move files around, access the terminal and some other debugging things. ADB is part of the Android SDK (Software Development Kit). You can get that here if you are interested: Android SDK | Android Developers

    Keep in mind the SDK is about 400 MB in size, and you only need the ADB.exe file and a few associated dll's for it to run (total of 312 KB).

    So, I would recommend getting the PERI tool from ThingODoom here: http://www.transformerforums.com/for...-firmware.html. We are NOT going to run the PERI tool, just use some of the files in it. These files are compatible with all TF models (101, 201, 300 and 700).

    Download and extract the PERI tool to an easy to get to directory (We will use C:\PERI)

    Next, plug your TF in to your PC via the provided USB charger cable. Do not use the dock, just plug it directly into the tablet. You should hear a new hardware found sound. Remove any microSD cards, SD cards or USB devices as we do not need to pull the data from them. You can leave them in, but it will pull the data across via USB and is not necessary.

    Open device manager (Control Panel - System - Device Manager)

    If USB Debugging is checked, you should see 2 devices, one will be a Portable Device, the other will be either under Other Devices or at the top under ASUS or Android Devices:

    Right click on the device and choose to UPDATE DRIVER.

    Choose the option to Browse:

    Point the wizard to the C:\PERI directory:

    Confirm that you want to install the driver anyway:

    Now the driver should be installed properly. Reboot if prompted.

    Next, we need to open a command prompt. Hold WIN+R and type CMD and tap OK.

    In the command window, type the following code:
    Code:
    c:
    cd c:\PERI
    adb devices
    You should see something like this:

    Be sure it shows a device listed.

    Next, we need to perform the backup. There are a lot of options you can use for your backup, but it can be executed with this code:

    Code:
    adb backup -apk -shared -all
    that is adb[SPACE]backup[SPACE]-apk[SPACE]-shared[SPACE]-all

    This will backup your device to the c:\PERI directory in a file called backup.ab

    After you issue the command, you will see this screen on your tablet:


    Enter a password if you would like to encrypt your backup and tap Backup my data.

    Once it is complete, you will be returned to a C:\PERI> prompt and your tablet will be back at its previous screen.



    RESTORING FROM A BACKUP

    Ensure your tablet is connected via ADB and you can see it by using this code in a command prompt:
    Code:
    adb devices
    Once you verify it can be seen, you will need to type the following code (assuming your backup is stored in C:\PERI\backup.ab)
    Code:
    adb restore c:\PERI\backup.ab
    Your tablet screen should show this:

    Enter your password if you encrypted with one and tap the Restore My Data

    Wait for it to finish, and you should be fully restored.

    Brilliant, thank you. A Christmas project.

    I've had my tablet for 6 months and haven't connected it to the computer yet.
    Happy owner of a TF300T

    Unhappy

    In Win7-64bit I am not offered the option of forcing the driver to install. It says "Windows was unable to install your ASUS Android Composite ADB Interface". I proceeded and the command line does not display any devices attached. I was so happy to see this procedure for my TF700T with android 4.2.1 but sadly doesn't seem to work.

    d:\PERI>adb devices
    * daemon not running. starting it now on port 5037 *
    * daemon started successfully *
    List of devices attached

    d:\PERI>

    Windows 7 64 bit does not allow the installation of unsigned drivers by default. Reboot your pc, press F8 and select the option to disable driver signature enforcement. Try again and it should work.

    All set up to try out this method, but since upgrading my TF700 to 4.2.1. I see no Developer Options in my settings... Can this really be true? I know it used to be right there before the update...
    Ok, so is there a workaround?

    Thanks

    Go to Settings - About - Build Number

    Tap this quickly 7 times to become a Developer.

    This is a new "Feature" to hide these options from most users.

    Thanks. It worked, but you forgot to mention the chanting of incantations and dropping frogs and lizards into my cauldron.
    Geez! :banghead:

    hi, i did the steps and i got the backup.ab file and its filesize is 159 KB
    so what did i do wrong? or it's just the way it is?
    what i want is to back up the entire system on my device (like all apps, system apps, system stuff, user stuff, everything) so i can restore later if i mess with the system like delete system app,....
    but only 159 KB seems like it only backs up the setings?
    and yes i used the command adb backup -apk -shared -all
    My device: White TF300T, Stock Android 4.2.1, NOT unlocked.

    (Sorry for delay) I did reboot with F8 and selected "disable driver signature enforcement" I downloaded PERI 0.4 zip file and put it in D:\PERI.
    In Android 4.2.1 I enabled "USB debugging" (verify app over USB" was unchecked). I removed the sd card and dock.
    Plugged into the PC installed ok. 2 devices were added to the device manager:
    "Portable Device - ASUS Transformer Pad TF700T
    Other Deivces - ASUS Android Composite ADB device
    The instructions do not say which one to install the driver on so I tried them both (rt.click - update dvr - browser - D:\PERI +subfolders). Same error for each.
    Windows was unable to install your [ASUS Transformer Pad TF700T|ASUS Android Composite ADB device]
    Command prompt "adb devices" listed nothing.
