At this point, with CWM Recovery you can now create a NANDroid backup (a backup of everything in your phone which includes the OS itself, system and user installed apps (only ones on the internal SD), contacts, messages etc.) It is one of the most important things to do before messing with your phone i.e. flashing ROMs, kernels, or apps. After you create a backup, the backup file would be located "sdcard0/clockworkmod/backup" for internally saved backup, and "extSdCard/clockworkmod/backup/" if it's saved to the external memory. This file can also be transferred to a different storage, say a hard-disk, if you need more space on your phone. And, If you do wanna create the backup right now, just . . .

1) Boot your phone to Recover Mode, by pressing the following hardware buttons at the same time: Volum Up, Power, and Home. When the device vibrates, release only the power button while still pressing down the other two, until you get the CWM Recovery screen.

In this mode, touch & swipe on the screen either up or down to move selection up & down, and swipe to the left to go back to the previous screen or right to select and option.

2) Select "backup and restore",

3) The next part is very intuitive, which is to select which memory would be the desired location for the backup file e.g. internal or external. Once you select an option, it will automatically start the backup.

4) Once done, you may proceed with the 2nd part of this rooting guide.​
