I want to backup data from a Windows (Vista) computer to a Synology NAS (210j). The NAS supports FTP, SMB, NFS and also allows a rsync daemon to be set up.

I want to backup different folders to the NAS, but I'd prefer to use the hardlink method to save diskspace (like this script does). With this method, a new folder is created for every backup, but if the file already exists on the target, only a hardlink is created.

The filesystem on the Synology device is ext3, so I probably can't use rsyncbackup, as it is made for NTFS. Is there another way to do this backup with hardlink support?
