Selective Time Machine copy My Time Machine backup has 100+ dated backups.  What I'd like to be able to do is extract the backups for a particular folder to another location, with the result being like TM's archive (where multiple references to unchanged files are just links to 1 copy).  Effectively, this would be a copy of the original TM archive, but only for the selected folder (and it's subfolders).  Is there any utility which can do this?
ditto didn't cut it, but rsync did.  It has a --link-dest option, that uses files in that folder as the base to link to for duplicates.  It's important that the source path for rsync end in /.

To prepare, in the location I'm going to store my copy, I create a symlink to the 1st archived folder I want to copy: ln -s -h -f /Volumes/MyBook\ 2/Backups.backupdb/Mini/2012-08-02-003832/Macintosh\ HD/Users/jerrybarrington/pathtothefolder/ /Volumes/MyBook\ /Volumes/MyBook\ 2/CK2.backup/Last.

Then to copy: sudo rsync -a --delete --link-dest=/Volumes/MyBook\ 2/CK2.backup/Last/ /Volumes/MyBook\ 2/Backups.backupdb/Mini/2012-08-02-003832/Macintosh\ HD/Users/jerrybarrington/pathtothefolder/ /Volumes/MyBook\ 2/CK2.backup/2012-08-02-003832/.

Lastly, update the symlink to point to the new copy: ln -s -h -f /Volumes/MyBook\ 2/CK2.backup/2012-08-02-003832/ /Volumes/MyBook\ 2/CK2.backup/Last.

For each subsequent copy, repeat step 2, changing both instances of 2012-08-02-003832 to the next date I want, and then repeat step 3.
