rsync - Oct 2004 - Problem with incremental backup - copies instead of hard links

Hi there,

I'm using this version of rsync:
localhost:~ mzehetle$ /usr/local/bin/rsync --version
rsync  version 2.6.0  protocol version 27

Basically incremental backup (--link-dest option) works with a 
destination on my local volume but not with a destination on a firewire 
volume. I have no idea why.
The only difference between the scripts is the destination and 
--link-dest path.
If both paths are on the local harddisk, it works properly, if the path 
is on a firewire disk it doesn't.

Here are the scripts and the terminal results:

The script that works (destination path on local harddisk):
#rotating backup script - v1.0
rm -rf "/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Backup Almaas 
Test/Backup Test.2"
mv -f "/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Backup Almaas 
Test/Backup Test.1" "/Users/mzehetle/Dokumente/Mischa Leben/1 
Arbeit/Backup Almaas Test/Backup Test.2"
mv -f "/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Backup Almaas 
Test/Backup Test.0" "/Users/mzehetle/Dokumente/Mischa Leben/1 
Arbeit/Backup Almaas Test/Backup Test.1"
time /usr/local/bin/rsync -vv --delete 
--rsync-path=/usr/local/bin/rsync -a --stats --progress --eahfs 
--showtogo --link-dest="/Users/mzehetle/Dokumente/Mischa Leben/1 
Arbeit/Backup Almaas Test/Backup Test.1/" 
"/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Almaas" 
"/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Backup Almaas 
Test/Backup Test.0/"

The script that shows different behavior (destination path on a mounted 
firewire harddisk):
#rotating backup script - v1.0
rm -rf "/Volumes/mac backup/backup/Test/Backup Test.2"
mv -f "/Volumes/mac backup/backup/Test/Backup Test.1" 
"/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Backup Almaas 
Test/Backup Test.2"
mv -f "/Volumes/mac backup/backup/Test/Backup Test.0"
"/Volumes/mac
backup/backup/Test/Backup Test.1"
time /usr/local/bin/rsync -vv --rsh="ssh -l root" 
--rsync-path=/usr/local/bin/rsync -a  --stats  --progress --eahfs  
--showtogo   --link-dest="/Volumes/mac backup/backup/Test/Backup 
Test.1/" "/Users/mzehetle/Dokumente/Mischa Leben/1 Arbeit/Almaas"
"/Volumes/mac backup/backup/Test/Backup Test.0/"

Try creating a hard-link manually between the actual destination dir and
the backup dir that is failing.  It might be that you are trying to
create a hard-link between two separate partitions (which is not
possible).  If that is not the case, try upgrading to 2.6.3.
