Les, good point! I recall enabling
--checksum-seed when I had this problem in 2010 but left his option commented
out in 'config.pl' when I built the replacement backuppc server..

Jeffrey, I posted the comment because
I was surprised that Debian 6/Squeeze was shipping an old version of File::RsyncP
given that 6.0 first came out in 2011 and Debian 6.0.10 (the version I
am running) was released in July 2014. I am used to the various Linux
tools for upgrading code but am not a Perl programmer so CPAN was not something
I had concerned myself about. Even getting the version numbers of
CPAN modules was not obvious - the answer is running cpan and entering
'i File::RsyncP'.------------------------------------------------------------------------------
