+### Scheduling Backups
+
+It's possible to schedule backups using Laravel's scheduler.
+
+```PHP
+/**
+ * Define the application's command schedule.
+ *
+ * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
+ * @return void
+ */
+protected function schedule(Schedule $schedule) {
+    $date = Carbon::now()->toW3cString();
+    $environment = env('APP_ENV');
+    $schedule->command("db:backup --database=mysql --destination=s3 --destinationPath=/{$environment}/projectname_{$environment}_{$date} --compression=gzip")->twiceDaily(13,21);
