Backup index.yaml


When using lxc export container container.tar i get the archive. If i extract it i can see a index.yaml file with specific content. Is there are way to get this content from using lxc command ?

I am asking because i have 300GB+ containers and export takes forever. Workaround is to mount the zfs and rsync the content by preserving the folder structure. I only have issues with generating index.yaml file.

Any advice on how to get it?
