BackupPC_incPartsUpdate

=head1 DESCRIPTION

Create C<.tar.gz> increments on disk calling C<BackupPC_tarIncCreate>.

Following options are supported (but all are optional):

=over 4

=item -h hostname

Update parts for just single C<hostname>

=item -c

Force check for tar archives which exist on disk

=item -d

Turn debugging output
