Dietpi-backup failing when backing up to Netgear ReadyNAS Duo

Thank, StephanStS

For those following, I have managed to gain access to the NFS server via ssh, which I could not do until today.

Here’s the exports file:

johnny:/etc# cat /etc/exports
"/nfs" *(insecure,insecure_locks,rw,async)
"/work" *(insecure,insecure_locks,rw,async)

/work was the original NFS share
/nfs is a new share I created today to see if I could get things working with a freshly created NFS share

Both shares fail with dietpi-backup
