adb backup lets you backup app data to a computer using the internal android stuff same as Google Backups use.
Safest to backup each app individually (dont bother with the apk)
Need to install the app again before restoring the backup.
There is also a decent non Google backup app, which is getting nice improvements, but it needs to be built into the android, a few will get it soon hopefully https://chaos.social/@hexmasteen/103039515584827964
