I'm not sure whether CIFS supports hardlinks.

You used the BackupPC package from your distribution? It probably
doesn't have the backup storage configured as /backups, but maybe
/var/lib/backuppc. The easiest way is to stick to that location and
mount your NAS there.

You may check whether hardlinks work correctly by opening a shell and
doing:

echo hello > testfile
ln testfile linkedfile
echo olleh > linkedfile
cat testfile

There should be no error messages and the last command should output
"olleh". If you do an ls -l testfile linkedfile, you should see
something like this:

-rw-r--r-- 2 root root 6 2009-03-26 16:25 linkedfile
-rw-r--r-- 2 root root 6 2009-03-26 16:25 testfile

- note the 2 here! It says: link count 2.

Hope that helps,

Tino.
