rsync - Oct 2009 - Problem with symlinks

Hi,

currently I'm trying to extend my existing backup concept but I have 
issues due to symlinks.


rsync has problems with symlinks. First some background information:
I regularly back up my / and /home from my desktop PC and my netbook to 
my Synology DiskStation (500GB) using rsync 3.0.6 with this script: 
http://pastebin.com/m43d4e353 . This works without any error messages. 
On the DS are also stored other files from two windows machines.

The DS has a built in backup feature that unfortunately has problem with 
hard links so I stripped down my script to directly run rsync 3.0.4 on 
the DS:

|# Backup source device/share/directory/etc
BACKUP_SOURCE=/volume1/thomas/

# Backup destination device/directory
BACKUP_TO_DEV=/volumeUSB1/usbshare/thomas_backup/

rsync -q -v -axH --no-inc-recursive --delete --exclude="@eaDir" 
$BACKUP_SOURCE $BACKUP_TO_DEV|

This handles the hard links (-H) but now I have problems with symlinks. 
When running the script I receive a lot of error messages from this type:
rsync: 
open(backup/sammy-root/2009-07-29/usr/share/pixmaps/cxassoc-cxoffice-0-application_x-crossover-exe.png)
failed!!: No such file or directory (2)
rsync: open(backup/sammy-root/2009-07-29/usr/share/qt/mkspecs/default) 
failed!!: Is a directory (21)
rsync: 
open(backup/sammy-root/2009-07-29/usr/share/texmf-dist/scripts/context/stubs/unix/luatools)
failed!!: No such file or directory (2)

Unfortunately the DS doesn't support the -v option so I have no
"normal"
output.

When I browse to the backup destination the files a there and it seems 
they point correctly to original file.

So, is this something I can ignore or can this be fixed?

Thanks in advance,

Thomas

Standard rsync does not produce such output containing the string
"failed!!".  Are you using the DS's custom version of rsync?  If
so, we
don't support it on this list and you should bug the manufacturer.
