rsync - Sep 2012 - Static files have vanished.

I'm confused about this, perhaps something is wrong with rsync?

rsync  version 3.0.4  protocol version 30
Linux ##### 2.6.32.59-0.3-default #1 SMP 2012-04-27 11:14:44 +0200 x86_64 x86_64
x86_64 GNU/Linux
$ cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 1

nfs
rw,nosuid,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=#####,mountvers=3,mountport=56892,mountproto=tcp,local_lock=none,addr=#####

I'm positive the files are not being changed, they are only updated when a
computer is installed or removed and the frequency of this, as you can guess, is
not such that these files should never(vary rarely ever) be considered vanished.

Nevertheless consecutive runs indicate they are in a state of perpetual
vanishing.

Cheers!
