The importance of backing up data cannot be stressed enough. Even with our mobile devices we should ensure that we take regular backups of our important data. Of course on Android, things like app data and contacts will be synced automatically to our Google accounts but this does not quite constitute a full backup.
Making a clone of one’s file system is sometimes desirable in order to be able to restore your device to its previous state after clearing all of your data and carrying out a restore. This article explores a solid way of doing this through what is called a Nandroid Backup.

The beauty of a Nandroid backup, however, is that it allows for the possibility of restoring your device to the exact state that it was in, prior to a factory reset, without having to worry about reinstalling apps and transferring data stored in other locations back on to your device.

Then select the partitions you wish to back up.
Depending on the amount of data that you have stored, the backup may take a while to complete so don’t be surprised if this is the case for you.
If you need to restore a backup, simply access the Restore option and you will be able to restore any backups that were made.
2. Android App
You can use the app Online Nandroid Backup to create a Nandroid backup as well. This app also requires that your device be rooted.
You will have to choose which custom recovery you wish to use as well as your desired storage location.
Nandroid backups offer users a means of creating complete images of their Android devices or at least just the partitions they desire. This is especially important for those of us who are always modding our devices with custom ROMS and the various other options that having a rooted device afford us.
