However, do not forget that in this case all applications and games are lost. Wi-Fi settings and other networks, system settings etc. And this is a very significant problem if dozens of those same applications are installed - since restoration can take an prohibitively long time.

On the main work screen, select the “Backups” tab. Press the “Menu” button on the phone and select “Processing” at the bottom of the screen. In the menu that opens, select “Back up all user software and system data” and click “Start” next to it. The program will prompt you to select all applications for backup. We are interested in a complete copy of the system, so we don’t change anything. After this, I start the process of creating a backup. The process may take different quantities time, depending on the quantity installed programs. Now in the “TitaniumBackup” folder on your memory card you can see a large number of files with backup copies, it is advisable to copy them to a computer or other device - you never know, suddenly microSD card will fail. It is also possible to configure automatic creation backups in the “Schedules” menu.

When the time comes and you need to restore the contents of your Android device, you can do this in several ways. Firstly, you can restore both applications and settings. Through the “Processing” menu item, go to the “Recovery” section and click “Restore all software with data”. You can also restore only individual applications– then in the “Backups” section select specific applications and click “Restore”. Don't forget that sometimes you need to restart your device before the changes take effect. In any case, Titanium Backup offers great amount options for creating and restoring backups, so you can always return your Android gadget to the initial state. If you need to restore a full copy of the operating system, that is, the firmware, then you need to use the alternative menu ClockworkMod recovery Recovery or similar.
