I have files with 3+ links that, according to BackupPC_tarPCCopy,
aren't actually linked into the pool.  See my other post.

Yeah, these backups are broken somehow; see above.

I don't know?  What should they look like?

/me finds BackupPC_attribPrint :)

I'm afraid it looks like a bug in your code.  :(

Example:

  Can't read size of 
/backups/pc/customer--tm50-e00145--tm50-s00339---shared/47/f%2f/fshared/fbubblevision/freports/fproduct_sales/fproduct_sales_2010-04-05_2334.zip
 from attrib file so calculating manually

Attrib file:

  $ ls -l 
/backups/pc/customer--tm50-e00145--tm50-s00339---shared/47/f%2f/fshared/fbubblevision/freports/fproduct_sales/attrib
  -rw-r----- 12 backuppc backuppc 86 Oct 12 18:04 
/backups/pc/customer--tm50-e00145--tm50-s00339---shared/47/f%2f/fshared/fbubblevision/freports/fproduct_sales/attrib

Contents thereof:

  $ sudo -u backuppc BackupPC_attribPrint 
/backups/pc/customer--tm50-e00145--tm50-s00339---shared/47/f%2f/fshared/fbubblevision/freports/fproduct_sales/attrib
  $VAR1 = {

      'mode' => 33188,
      'size' => 3527103,

    },

      'uid' => 1000,
      'mtime' => 1270535436,
      'mode' => 33188,
      'size' => 3527103,
      'sizeDiv4GB' => 0,
      'type' => 0,
      'gid' => 415,
      'sizeMod4GB' => 3527103

      'uid' => 1000,
      'mtime' => 1270535162,
      'mode' => 33188,
      'size' => 3527103,
      'sizeDiv4GB' => 0,
      'type' => 0,
      'gid' => 415,
      'sizeMod4GB' => 3527103
    },
    'product_sales_2010-04-05_2334.zip' => {
      'uid' => 1000,
      'mtime' => 1270535712,
      'mode' => 33188,
      'size' => 3527103,
      'sizeDiv4GB' => 0,
      'type' => 0,
      'gid' => 415,
      'sizeMod4GB' => 3527103
    }
  };

As you can see, fproduct_sales_2010-04-05_2334.zip *does* have an
associated size.

As a random side comment, it's amazing how much interesting stuff
I'm finding.  :)  I wonder if our BackupPC install is now the
largest in the world; just under 25 TiB across 5 hosts and thousands
of clients.  I suspect I'm hitting so much stuff because no-one has
tried to productionalize it at this scale before.
