How to install rbd and use it directly from TrueNAS SCALE?

[kamuzon]

Hi. I have some cephs in my network.
And I need to make backups of virtual machines virtual disks.
So how can I install rbd "client" on TrueNAS Scale to do:
rbd snap create
rbd export
rbd snap rm
and so on
directly from TrueNAS without using any of ceph cluster nodes?
Thank you.

You can use ZFS snapshots and ZFS send and receive to a suitable target system. You cannot install additional software on TrueNAS outside of VMs or containers. TrueNAS is an appliance with a fixed feature set. If you force install additional things, you are likely to break it.

Seems to me you would use the ceph/ceph container from the Launch docker image button and then connect to that container with CLI.

But as @Patrick M. Hausen says, you can't really interact with the ZFS local storage with that.
