How To Perform Nandroid Backup, Restore With CWM Recovery On Android

Nandroid backup is one of the perfect and complete backup solution for the rooted android user. Which means this is a entire ROM data protection method. Application based method can’t do this process, they only backup system and user app with data, cache. This method based on the custom recovery. We highly recommend to perform a nandroid backup, before the advance customizations and install new custom ROM or firmware. Some devices have a native recovery option, but they’re not available backup and restore features. If your device has a native android system recovery such as Samsung 3e or similar, you can flash a custom recovery such as clockworkmod, CWM based one or similar recovery.

This advanced root backup method takes a snapshot of your internal memory and its system partitions. After you have completed this, your files saved on the SD card/external memory ClockworkMod folder. Keep that files securely, also you can copy it to the computer or any-other storage device. This tutorial I use clockworkmod recovery nandroid backup. If you have another custom recovery, such as TWRP (Team Wind Recovery Project) most of the time backup and restore steps are similar.

Following screenshot is the CWM recovery main menu (non touch version). There’s no major differences between touch enabled and non touch version. If you have a non touch use your volume keys for navigation. Selection differs from manufacture to manufacture. Some devices Power button for selection some devices home button for selection and some of the Sony’s devices use on screen navigation button specially Xperia T (soft key available devices).ClockworkMod Recovery
