STEP 1. First you have to download .deb file from here.
STEP 2. Now you have to copy the .deb file to /var/mobile/ and then simply install it via iFile.
STEP 3. In order to backup your iOS device simply launch MobileTerminal and then type:
- ibackmyi ( all lowercase )
STEP 4. In order to get the backup simply go to /var/mobile/media/iBackMyi
That’s it. In this way you can backup your iPhone, iPod touch, and iPad using iBackMyi. You should note that still the script is in beta stage so you have to use it at your own risk. You can watch the video embedded below to see it in action.
Using iBackMyi you can backup Cydia sources list, Tweak preferences, AppStore list, iFile Bookmarks, List of Cydia pacages installed on your iOS device, List of themes installed on your iOS device, Description of Cydia packages, SMS database, call history, Safari bookmarks and browsing history.
