Asking for ideas/suggestions: how to setup NFS server (ganesha) with continuous backup?

[Tony]

Hi,

I need to setup a NFS server with continuous backup (for example every 5 min). Any suggestion how to do it please? At the moment I am considering these options:

(1) LXC container with bind mount to a ZFS volume; NFS server via nfs-ganesha inside LXC, backup via ZFS snapshot on node
(2) ZFS inside VM, aka nested ZFS or ZFS on ZFS.
(3) VM with direct access to raw disks in node, and setup ZFS inside VM

Thanks in advance for any hint.

I gave (1) a try, but it seems running nfs-ganesha inside a LXC is not trivial. Anyone here has experience with this?
