Sadly the old server is gone so rerunning the backup is quite a bit of work.
I will have to setup a new server, restore the backup, make another backup and restore it again 
If there’s no other way then I will have to do it, but I’m hoping dropping the 2 tables and recreating them will fix it as well.
Nextcloud seems to be running fine without being able to read them.
I’m pretty sure the next update will be a problem tho’…
