--- title: Requirements weight: 3 --- This backup package requires **PHP 7.3**, with the [ZIP module](http://php.net/manual/en/book.zip.php) and **Laravel 6.0 or higher**. It's not compatible with Windows servers. If you are using an older version of Laravel, take a look at one of the previous versions of this package. The package needs free disk space where it can create backups. Ensure that you have **at least** as much free space as the total size of the files you want to backup. Make sure `mysqldump` is installed on your system if you want to backup MySQL databases. Make sure `pg_dump` is installed on your system if you want to backup PostgreSQL databases. Make sure `mongodump` is installed on your system if you want to backup Mongo databases. To send notifications to Slack you'll need to install `laravel/slack-notification-channel`: ```bash composer require laravel/slack-notification-channel ```
