Apple has always pointed out that links are used in subsequent backups of unchanged files to keep the backup from consuming too much space. I think the assumption behind Time Machine is that the user is not going to use something like Finder to delete files from backups.I know Time Machine deletes older backups if you are in a pinch for space. I figured that some variation of the following procedure takes place when TM deletes backups.1. The backup that is about to be deleted is identified (oldest backup).2. Any unmodified files that are original files (not links) are moved to the next oldest backup.3. The hard links are updated for files that were moved.4. Oldest backup deleted.</blockquote>
