I am wondering if there is a different possibility to perform a backup of a single rancher 2.0 container as that described in the docs. Creating new (versioned) containers with volume from “live” container is somewhat cumbersome in my opinion. Is there a possibility to “just backup” a bind-mount volume from the container (e.g. etcd data), so I can handle this like “normal” file system based backups (instead of container-based)? Currently I am not sure, what are the prerequisites to backup /var/lib/rancher. I am thinking of rotating those backups and pushing them to some external storage, which is rather simple when just using backup files.
Thanks in advance.
