Titanium Backup has been working fine for me to backup and restore various apps. Are there features missing or problems with TB's implementation on modern Android versions?
There are very well-known problems with Titanium Backup not being able to backup/restore newer APEX and multi-part APK types. It can also cause system configuration corruption/resets on certain special/meta backup items. Google for more info.
It may not even run on some Android 13 and later devices due to a common error of not being able to detect root status.
