backup: Error: unsupported fs type nfs

[bread-baker]

This is probably a known bug, but a container having an nfs mount does not work. To get around this issue, I have a backup scheduled using mode: 'stop' .

We will eventually be moving the nfs server to the proxmox-ve server, so this problem will go away for us..
It would be nice to have the NFS issues fixed.
--------------------------------------------------
102.mount:
mount --bind /home ${VE_ROOT}/home

/home is an nfs mount on the host:
df /home
Filesystem Type Size Used Avail Use% Mounted on
10.100.100.10:/home nfs 75G 8.5G 66G 12% /home
