Cloud not backup a bind-mounted Volume on EC2 /opt/rancher not found

I tried to run the rancher in aws EC2 docker container :

docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher:v2.4.1

When i was following the tutorial to backup the bind-mounted volume, i could not find /opt/rancher directory, it’s normal ?

The container was running, and i stopped the container the same case.

Any idea ?
