I noticed that the rsync is running as root. As "root" user on the client,
are you able to mkdir directories or touch files on the NFS mounted
directory ? NFS servers by default do not allow write access to exported
directories by "root" user on clients (user "root" typically gets mapped to
user "nobody"). If you need write access as "root" user from the NFS client,
the NFS server typically would have an option (like "no_root_squash" or
"--maproot=root") while exporting the directory to allow this. If you're not
already doing it, you might also want to restrict the NFS exported directory
(on the NFS server) to only the clients from where you need access to them.

Also, when using rsync to transfer data between machines, a rsync server
would be a good alternative to consider (instead of exporting directories
using NFS)
