Incremental backups seem to be buggy, especially when doing restores.
Create a user.
Create multiple domains.
Do an incremental backup.
Save the restic key.
Delete the user (or just delete the web/mail/dns without deleting the user, either way has the same issue)
Restore the incremental backup with the restic key (or just use the panel to do the restore if you did not delete the user)
Only 1 domain is restored… and nginx is broken.
I tried this multiple times with the same results.
It also breaks nginx because it restores the nginx domain config bad. So, nginx cannot restart when you add new domains, or when you stop it.
Then, if you delete the bad user, it works again … but only if you have not yet created another user. If you did, that that new user causes issues as well.
