Thanks, @Dabuh.
This is also why I am considering using OandBackup, too. But there is another thread on backing up data which makes me insecure about its reliability:
https://forum.fairphone.com/t/backing-up-app-data-in-rooted-phones-whats-your-experience/38314
It says here: “… and Oandbackup , like many other backup apps, record app data but don’t record system permissions and owners for each directory and file, so restored apps won’t work most of the time, and system integrity is compromised.”
Is that still an issue?
