Installing TWRP Recovery on a smartphone like the Sony Xperia M4 Aqua leaves people pretty happy nine times out of ten. One of the features that often gets overlooked that is available from a custom recovery image like what Team Win has produced is the chance to take full backups. Usually, there is only one way to make full backups, and that is by installing ADB on a computer and then executing some ADB commands from the command line when the ADB is installed. A custom recovery environment offers what is called an NANDroid Backup, and it is built into just about every custom recovery that is worth installing.
Team Win’s TWRP certainly has it and with the tap of a button you have backed up everything that is on the device. There’s no need to install any apps from the Google Play Store like Helium to help you backup the application data that is often so annoyingly difficult to backup. What is more, a custom recovery partition like TWRP that offers the NANDroid Backup option can also be paired with the NANDroid Manager application that is available for rooted Android users. The NANDroid Manager can allow you to restore single partitions of data at a time whereas restoring a traditional NANDroid Backup from the custom recovery itself would result in all data being restored. That means you can restore the apps and no restore anything else for example if you install the NANDroid Manager app.
