<?php
    public function process(string $filename): void
    {
        $extension = pathinfo($filename, PATHINFO_EXTENSION);

        switch ($extension) {
            case 'gz':
            case 'gzip':

                break;

            case 'bz2':
            case 'bzip2':
                $this->compressor = CompressorFactory::create(Option::COMPRESSION_BZIP2);
                break;

            case 'sql':

            default:
                throw Exception::unavailableDriverForcompression($extension);

It seems like $extension can also be of type array; however, parameter $extension of Dimtrovich\DbDumper\Exceptions\Exception::unavailableDriverForcompression() does only seem to accept string, maybe add an additional type check?

$handle is of type resource, thus it always evaluated to false.
