How to Backup you device

Now that we have gotten fairly good at flashing Custom ROM, the biggest challenge we face is to restore all the application and application data we had earlier on our phone before going flash happy. It is often a very cumbersome task to download all you apps again from the PlayStore and the irritation goes to another level if we are in the midst of playing a big game and had completed 20 levels out of 22.

Once we do a Factory Reset/Data Wipe from the recovery menu all our saved data is lost and hence the Games and Apps.

In this blog I will update you on how to backup your device, your data and your apps effectively.


  1. Backing up your device
To effectively backup your device before flashing any custom ROM, you will need to have ClockworkMod Recovery installed. If you dont have it or dont know what it is, read my guide in Part 1 or visit this page.
Once you have CWM installed, reboot into Recovery by pressing and holding Volume Up+Power+Home buttons together, release the buttons only when you see the Recovery Menu come on the Lcd.

Navigate to Backup and Recovery, Choose Backup from here.
This option will then backup all the system files, apps, app data and settings which you have on your device. There are two things which are not backed up here:

  1. Your data on Internal/External Sdcard
  2. Your Modem or Radio
Once the backup has completed, it will ask you to reboot the device. Reboot and you are backed up against any flashing misfortunes.

To Restore this backup just navigate again to backup and restore option in CWM recovery. Choose Restore option from here and Select the Backup you want to restore.

This is also known as Nandroid Backup

  2. Backing up your Applications and Application Data

Performing a Nandroid backup will not be useful if you want to try out a new ROM, as all the applications will be in the Nandroid backup and restore it you will have to restore the complete backup.
The best option here is to use Titanium Backup Application from the PlayStore. Get this app from here.
You will need to be rooted to use this application.
Now to backup your apps, fire up this application and grant it Superuser permissions.
It will show you all the apps which are not backed up. Choose the option of backing up all the apps with data.
It backs up all the apps and data on your internal sdcard.
Now after flashing a Custom ROM/New ROM you can restore all your applications to the same state by again going in TB and clicking restore all apps with data.

It is advisable that you dont restore System Apps and System Data if you have moved onto a different ROM, otherwise you will end up in Force Closes and unresponsive system.

   3. Backing your SMSes

Another important data which we dont want to loose are our SMSes. To backup the SMSes we will use another application knows as SMS Backup and Restore. Get it from the PlayStore from here.
Open up the Application and click Backup. It will ask you for a name, give the backup a name preferably with a date. Now, you also have an option to save this backup in your dropbox account along with the SDcard. For it you will have to download an additional add-on for this app from here.
Once you have to add-on installed, navigate to Preferences>Backup Settings and Configure your Dropbox account here. Check that the Upload to Dropbox option is ticked. You can also configure a schedule for it to do the backups automatically and at the same time uploading it to Dropbox.

  4. Backup Contacts

This is already done by Google and all your contacts get backed in your Google account automatically.
Just ensure that you have added a Google account in your phone and the sync option is turned On.

I hope after following all these steps your are fairly protected against any misfortunes and can go and flash as many ROMs as you want.

Enjoy the Android Goodnes !!
