I'm trying to take full backup using "adb backup -all -f path" and it took backup and stored in my PC.

When i try to restore it using "adb restore path" then it restored into the target device.

ADB backup command is not taking backup of messages, contacts and pictures. Kindly guide me if im missing something.

I could see that i have to use "adb root" to take backup using pull command. Will the device warranty be there if i use adb root command?

Thanks you with anticipation

    I'm voting to close this question as off-topic because it's not about programming, but about product warranty – Tim Jun 27 '16 at 14:47

if you root your device, it won't be under warranty anymore. Few applications actually don't allow backup by settingandroid:alloweBackup = "false" in android manifest file.This is true for both message and contacts. Also it depends on which version of android you have. You can see this AndroidManifest.xml file

  • Thanks for your reply But Then how does MDM tools like [MobileGo](http://mobilego.wondershare.com/) and [MobileEdit](http://www.mobiledit.com/) do this seamlessly – SeekeR Jun 22 '16 at 12:05
