I suspect that you have (multiple) backups in the pc tree that are not
linked to the pool...

The following is a quick-and-dirty hack to find non-zero length
*files* in the pc tree that have fewer than 2 hard links (note this
will miss files that are linked to themselves but not to the pool):

cd /var/lib/BackupPC/pc/; find */*/* -type f -links -2 -size +0 | grep -v 
"^/[^/]*/[0-9]*/backupInfo"
