I admire your perseverance!

This sounds like a bug in V4, to me.

Just to be clear, we're talking about the size number reported here,
correct, on the "Host <foo> Backup Summary" page?
-----------------------------------
File Size/Count Reuse Summary                                                   
                                                                                
   Existing files are those already in the pool; new files are those added to   
   the pool. Empty files and SMB errors aren't counted in the reuse and new     
   counts.

                         This number, 76330.2.
------------------------------------------------

If this number is wildly inflated by the presence of lots of
hard-linked files, then the results are very misleading.  In the worst
case, it might not be clear that you could restore the backup to the
disk it came from.

Am I right?
