Usage of the classes for permanent storage:
Použití classes pro permanentní úložiště:

<?php
$journal = new AppFileJournal(DATA_DIR . '/user/');
$driver = new AppFileStorage(DATA_DIR . '/user/', $journal);

// Get the cache tags
$tags = array();
$tags[] = self::USERID . self::SEPARATOR . $data->user->id;
$tags[] = self::TIMESTAMP . self::SEPARATOR . $data->timestamp;

// Get the key
do {
    $key = sha1(uniqid(time()));
    $has = $driver->read($key);
} while(!empty($has));

// Store the metrics into cache
return $driver->write($key, $data, array(\Nette\Caching\Cache::TAGS => $tags));
?>

Searching within the storage:
Vyhledávání v rámci storage:

<?php
class Mine {
    const USERID = 'userId';
    const TIMESTAMP = 'timestamp';
    const SEPARATOR = '/';

    /**
     * Find data by the user id
     *
     * @param int $userId
     */
    public function getDataByUserId($userId) {
        $journal = new App\FileJournal(DATA_DIR . '/user/');
        $driver = new App\FileStorage(DATA_DIR . '/user/', $journal);

        $tag = self::USERID . self::SEPARATOR . $userId;
        $nodes = $journal->findNodesByTag($tag);

        foreach($nodes as $node) {
            dump($driver->readByFilename($node[App\FileJournal::DATA][App\FileJournal::KEY]));
        }
    }
