@schapplm, I can see the watchedlist.db in the addon_data folder.

Let me explain a little further. I'm running Kodi 18.3 on an Android device. I've set the number of backups to 1.

I can see the backup file in the addon_data folder: yyyymmdd_hhmmss-watchedlist.db.zip. So it appears that it does the backup task, but the funny thing is, that the zipfile is empty.

I will set the number of backups to 0, if you're unable to reproduce the problem and can't fix it.

The backup addon from the Kodi repository does the backup job flawlessly. Maybe you could use a part of the code of this addon.
