Before casting mistaken aspersions about how backuppc works, why did
you delete the '--delete' line in the default rsync args?
>From stock config.pl for backuppc 4.x
NOTE how the comment says "DO NOT EDIT (emphasis added) the first set
unless you have a good understanding of rsync options.
#
# Arguments to rsync for backup. Do not edit the first set unless you
# have a good understanding of rsync options.

$Conf{RsyncArgs} = [

'--recursive',
'--protect-args',
'--numeric-ids',
'--perms',
'--owner',
'--group',
'-D',
'--times',

'--delete-excluded',
'--one-file-system',
'--partial',
'--log-format=log: %o %i %B %8U,%8G %9l %f%L',
