Backups are quite important due to the role they play in preventing data loss. Nandroid backups are a backup option for persons with Android devices which are rooted. They are done through a custom recovery such as Clockworkmod Recover or Team Win Recovery Project(TWRP). An Android recovery is a tool which basically offers you the ability to try to recover your device in the event of a software error or if you simply wanted to revert your device to factory default setting.

A nandroid backup allows for the backup of either your device’s file system or of individual partitions. Which option is chosen is up to the user as they may not have a need for backing up everything on their device.
How It Works
We will be illustrating how to make a nandroid backup with TWRP. Carrying one out with other custom recoveries will be quite similar.
First, you will need to boot your device into recovery mode. This will vary from device to device so you will need to do some research as to how to carry this out for your particular device. After entering into your custom recovery you will need to select the Backup option.
In Backup, select your desired partitions and then swipe to carry out the backup.
Congratulations, you have now created your first Nandroid backup! You will now be able to restore backups using the Restore option.
You will be able to browse your backup files from within Restore and pick which one you wish to restore.
The great thing about TWRP is that it is touch based unlike Android’s stock recovery which requires users to navigate its interface using the device’s hardware buttons/
This is not the only way of backing up data on your Android device but what sets it apart is it’s ability to backup your entire file system.
This is quite a comprehensive means of backing up your Android device and should be pursued if possible. The only downside is that your device needs to be rooted in order to carry it out. However, if you are indeed rooted, give it a shot.
