VitaBackup is a simple tool that could save you a lot of headaches caused by losing important files to your PSVita. This homebrew utility lets you backup up the following important pieces of data by just pressing a few buttons:
Encrypted and decrypted save data.
Trophy information
System Settings and User Information (handy to have if you restored your PSVita or are switching to another one)
User and Hardware IDs
Software licenses, these are linked to your PSN account
The application database or, in layman’s terms, the layout of the icons on the screen. – It’s a very good idea to back this up if you’re messing around with how some bubbles look!
Activation data – The importance of the activation file isn’t as great thanks to NoNpDrm and ReNpDrm. That being said, having it could still save you some time and headaches when it comes to setting up the aforementioned plugins.
VPKs – You can tell the program to backup VPKs found in ux0:/vpk/ for some reason. (VHBB doesn’t download/cache its VPKs there so I personally don’t really think that this option is necessary)
