The procedure given above by turning off the smartphone and then rebooting it to the recovery mode will involve a lot of time. In this process, you need to keep your phone offline for a considerable time and in the meanwhile you might miss a few important calls and may be some important messages too.
Let us now see a very fast and easy method. We need to use a simple app to take a complete ROM backup. You need not even switch off your phone. You can save 50 to 60 per cent of your time by using this method. All you need to do is to go to Google Play Store and download a free app developed by Ameer Dawood. The main purpose his developing this app is to save the time of the users from rebooting the system and entering the recovery mode. So, first install the two apps called Online Nandroid and BusyBox Installer.
The first app takes Nandroid backups while you are online. This helps to avoid rebooting and getting into recovery mode. This app backs up the partitions like boot, recovery, system, data, cache, cache data, dalvik cache, android secure, sd-text, Appslog and any other such partitions which might be on your phone. Remember that the format of the date used for the folder name will be the same used by CWM. CWM recovery will safely restore the Nandroid back-ups with the app Online Nandroid.
First start the BusyBox and update the version from the internet. This is a must step because once you run the Online Android app, it will detect the BusyBox version and will exit if the BusyBox version is not updated. As a matter of fact, Online Android is a script with graphical user interface running in the background to take the backups. The user needs to install this script initially and then the Online Nandroid will automatically perform this job. If you do not have the script the Online Nandroid app will prompt you to download one and you have to click 'Yes' from the dialogue box that will appear. The app will download and install the latest version of the script at the required location. The user is now ready for a Nandroid without rebooting.
Select the name format of your backups on the Online Nandroid screen. Preferably use the custom name since you can add the ROM name, date and time as per your choice. Now select from the custom name and click the 'Start Backup' button. Confirm the action on the next screen. A new screen will prompt you to enter the custom name of your backup. Fill up your requirements and click on 'OK' button. The backup will now start instantly and you can see the process on the screen. The entire process will not take more than 5-10 minutes depending on the speed of your phone and the type of ROM. Finally, the backups will be stored in the folder '/SDCARD/ClockWorkMod/Backup//'. Anytime you can safely restore the backup using the recovery mode.
