OOps I forgot to show the mount on client (linux) side:

grep /nfs/bk /etc/fstab
  2x.local.lan:/rrsnap/gv   /nfs/bk   nfs4 defaults 0     0

The disc where the directory /nfs/bk lives, and the nfs share is
mounted, does have noatime set.

/dev/sda3        /            ext4     noatime         0 1

The backup includes /var/ so I guess the cache and maybe a few other
places may have a goodly number of smallish files but I doubt it would
number in the millions.
