I just realised that you’ve also got an option just to restore the data. I just tried that out, and restored the notepad data from about a month ago. Did work, flawlessly. You will need to reboot your device after restoring.
NB, while the user interface of TitaniumBackup is not the most user friendly I’ve seen, it’s a good piece of software which saved my ass several times. I did buy a Pro key, which was worth every penny.
