  • AptBackup is a free app under the repository of BigBoss. You can download it from the Cydia Store.
  • It provides a very easy process to backup and restore all the jailbreak apps. All you need is to launch the application and it will start doing the backup process for you.
  • For the restore process, you have to download the AptBackup again from Cydia. Press the restore button and an automated system will do the who thing for you.
  • The AptBackup application makes a text file with the jailbreak apps you have installed when you try it for the backup. This text file is saved by the iTunes. When you restore you iDevice, AptBackup will use this file to know what to download.
