I wrote a program a while back that among other things checks for
unlinked files in the pc heirarchy. If an existing pool entry exists,
then it deletes the pc entry and hard links to it. If not, then it
moves the pc entry to the pool and hard links to it. The program is
called BackupPC_fixLinks.pl.

It also looks for duplicate entries in the pool and eliminates them.

If you think that may be helpful, I can send you the latest version.

My only caveat is that the program was designed for finding isolated
numbers of missing links caused by errors in linking due to an
nfs/ext3 bug on my NAS device (I typically had about 50,000-100,000
bad files to correct).

The program is by no means optimized to relink an entire tree.
