rsync not syncing desktop folder

[HomeRun4711]

Hello!

I found a strange problem while using rsync to backup my files.

I use a script:

------------------
#!/bin/bash

SOURCEDIR="/"
TARGETDIR="root at DLINK-13F017:/mnt/HD_a2/administrator/RAIDBackup/"
LOGFILE="--log-file=/home/administrator/.rsync/rsync_dns323.log"
OPTIONS="-avz -e ssh --stats --progress --delete --delete-excluded"
EXCLUDES="--exclude-from=/home/administrator/.rsync/exclude_dns323.txt"

sudo rsync $OPTIONS $LOGFILE $EXCLUDES $SOURCEDIR $TARGETDIR 2> 
/home/administrator/.rsync/errorlog_dns323.txt
--------------

Exclude-From contains:

- /dev/
- /sys/
- /proc/
- /home/administrator/.gvfs/
- /home/administrator/.rsync/rsync_dns323.log
- /home/administrator/temp/NAS/

------------

Well, everything is copied as expected I guess, exept ~/Desktop/.
The directory on the target side -  the file manager says there is no 
content.

I even cannot access it via console using su or sudo, I get permission 
denied.

This has surely something to do with the rights, but I don´t get the clue.

~/desktop/-folder source-side:
750 drwxr-x--- administrator root

~/desktop/-folder target-side:
750 drwxr-x--- administrator administrator

I hope you can help me!

Thanks,
