What is a Nandroid Backup?

It is a full backup of the partitions on your device’s NAND flash (NAND actually stands for NOT AND, which in simple terms means an electronic gate). Basically a backup of your phones hard drive if you will...
The Nandroid Backup is a snapshot of your device (it means everything on your phone – your apps, data, your current ROM and even the kernel is backed up) at the time you do the back up. If you restore the back up, it changes your phone BACK to that state. You will need clockworkmod (CWM/TWRP). So make sure you have CWM on your device.

The SD Card data is not backed up in the process. Although, the Nandroid Backup itself is created on your SD card. Make sure you have enough space on your SD card to make a COMPLETE copy of your phone.
It’s highly recommended that once you have done a backup, you manually copy it to your computer in case your sd card is wiped or corrupted.

Pre-requisites:

1. Rooted Device:

2. Custom Recovery (CWM or TWRP)
While the OS is running you cannot do a backup. The boot loader in the recovery enables you to take a backup of the OS while it’s not running.


How to Make a Nandroid Backup via CWM:

Backup via CWM:

1.Boot into Recovery pressing in the same time Volume Up + Home + Power buttons for our Galaxy S Advance phones

2. Select ‘Backup and Restore’ from the recovery.

Once you are in recovery, scroll down to the option ‘Backup and Recovery’ with volume Up/Down and select it (Power button for select).

3. Start the backup.

Once you are on the Nandroid screen, select ‘Backup’ to start the backup process. You have the option to ‘Restore’ backup on the same screen.

The backup process may take a while. Take a break for a coffee. :D

4. Transfer the backup to your computer (recommended).

Once you reboot, you can see the backup in the ‘clockworkmod/backup/…’ (or similar file) directory on your SD card.

Move, copy, or paste this folder on your PC safely.


Restore from a Nandroid Backup via CWM:

1. Boot your device into CWM and navigate to the Nandroid screen.

2. Choose ‘Restore’ and begin the process.

If you select ‘Advanced Restore’ option, you may select which part of the backup to restore – i. e. the boot,system, data or cache. Or choose the whole backup.

3. Reboot your device. Your system is now restored and is exactly the same as the time when the backup was taken.

Agreed. This needs to be incorporated into the CWR guide.

Thread Closed....But I will also give you ownership of the 2nd post over in that thread so you can port this over.

Edit: I gave you #2 and 3 and moved this over to that thread for you.
