If you are familiar with Rooting and installing Custom ROMs then you probably heard the term Nandroid. I'm going to explain to you what a Nandroid backup is and how you can make one.What is a Nandroid backup?
A Nandroid backup is a actually a complete backup of your entire current Operating System. It backups the NAND flash, something like the hard drive of your device. A Nandroid backup can mean the difference when you install a Custom ROM or when you play with the roots of your device and something suddenly goes wrong.
It is always recommended to make a Nandroid backup when you are going to install a Custom ROM. You can simply restore the backup and your Operating System that you backed up will be completely reverted on your device.
How to make a Nandroid backup?
In order to make a Nandroid backup, you are going to need to install a Custom Recovery (CWM). After installing this, the process is as simple as it can get.
Just enter Recovery Mode on your device and look for the 'backup and restore' or 'Nandroid' option in the Recovery menu. Select to make a Nandroid backup and wait a few minutes until the process gets done.
You should always save your Nandroid backups on the external SD card or on the PC to avoid erasing it by mistake because of a data wipe or something similar.
The Nandroid backup only backups data from the internal SD card, so everything on the external sd card has to be manually backed up
How to restore a Nandroid backup?
If you want to restore a previously made Nandroid backup, just enter Recovery Mode again and this time select Restore. Everything should go back to normal in a few minutes.
Remember that it is always better to have a backup than to not have one. It only takes you a few minutes but it can save you from a lot of trouble in the future.
