Save jailbreak apps before updating
Open Backup will then save all the Cydia Packages to either i Cloud or i Tunes.
Besides, it will also save a copy into your filesystem at private/var/mobile/Library/Preferences/Open Backup Files (if you are backing up your i Phone).
So far, Open Backup is the easiest option to backup your apps and tweaks. It is free and the interface is extremely easy to use.
There are times when we need to backup Cydia apps in our i OS device, for instance, upgrading i OS, rejailbreaking your device, downgrading i OS, and restoring i OS.It could be a headache if you have to write down all the jailbreak apps and tweaks you have in your i OS device on a piece of paper and then reinstall it one by one.Except Open Backup, you may also try Apt Backup which backup a name list of all the apps (just the name of the apps, not the apps themselves) in your i OS device.This app is free but you will need to reinstall all the apps one by one after that. It may sounds expensive to those who don’t feel their apps are important but it is very cheap to people who have apps that worth hundreds of dollars in their i OS device.
It takes just a few minutes for a complete backup depends on how many Cydia packages and apps you have in your i Phone, i Pad, or i Pod Touch.
Once the backup is completed, you can upgrade your i OS version and jailbreak your device again.
