ok, so suppose it is "12345.html.en"
...

if ($article_file =~ /^([a-zA-Z0-9_-]+\.html.?\w?\w?)$/) {
    $article_file = $1;
} else {
    $article_file = '';
}

ok, matches, so it's still "12345.html.en"

$article_backup_file = $article_file;

still "12345.html.en"

$article_backup_file =~ s/\.html$/_backup.html/;

still "12345.html.en"
(because \.html$ did not match)
