Thanks Terry for your quick response!
This looks like you have multiple hard links to the original files in the
directory being backed up. So each directory adds up all the hard links
in it and gets 1.7GB. But across all of them, you have files that are
only hard linked in some of the directories and not others. So, the
entire disk space that is being used is counted only once for each hard
link and comes out to about 2.7GB.
To find out which are hard links -
Use ls with a -i1. Note the first number on the line. so...
ls -i1

Note the hard link of inode#292932 above.
