It seems the directory “manual_flags” is missing, I assume because it’s not created on update and you don’t have custom HTTP routes.
Please check the files and directories in traefik:
[root@ns8rockytest ~]# runagent -m traefik1 ls -l

If the directory “manual_flags” or other dirs don’t exist, just create them:
runagent -m traefik1 mkdir manual_flags
Now the backup hopefully should work again.
