the backup can only write 2GB (some old filesystems and nfs-v2 has this limit).
What kind of filesystem is the nfs-share and which nfs-version do you use?

Can you produce on the nfs-server a 32GB-file on the share?

Oh, great. Thanks. I solved it. It was a problem with the version of the NFS server. I'm running NFS v4 now. All is fine.
