-BackupPC_incPartsUpdate
+BackupPC_ASA_PostArchive_Update
=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
