I can: there are none. BackupPC_tarCreate gets a list of path names to include
in the tar. Each of these is looked up verbatim and included (with
substructure if it happens to be a directory).

It should be *fairly* simple to patch BackupPC_tarCreate for the simple case
you need. A more general case would add an option and include correct handling
of hardlinks and symlinks. In sub TarWriteFile, after the calculation of
$tarPath and before the big file type "if" (line 455 in the 3.3.0 source),
I'd add

        return
          if $hdr->{type} != BPC_FTYPE_DIR and $tarPath !~ /\.pdf$/i;

(omit the "i" modifier if you really only mean lowercase "pdf"). Note that
this is once again completely untested ;-).

Hope that helps.

Regards,
Holger
