Backing up can be simple with tools like Forge and https://spatie.be/docs/laravel-backup/v8/installation-and-setup

I guess you can use Spatie Backup for all of it but I use it only for files with DigitalOcean

Once installed I just make a filesystem.php addition

        'backups' => [
            'driver' => 's3',
            'key' => env('DO_SPACES_KEY'),
            'secret' => env('DO_SPACES_SECRET'),
            'region' => env('DO_SPACES_REGION'),
            'bucket' => env('DO_SPACES_BUCKET'),
            'endpoint' => env('DO_SPACES_ENDPOINT'),
            'use_path_style_endpoint' => true,
        ],

Then I fill in the .env as needed.

They provide a backup.php file that by the time I am done looks like this

<?php

return [

    'backup' => [

        /*
         * The name of this application. You can use this name to monitor
         * the backups.
         */
        'name' => 'sites_name_files',

        'source' => [

            'files' => [

                /*

                 */
                'include' => [
                    storage_path(),
                    public_path(),

                /*

                 *

                /*

        ],


        'temporary_directory' => storage_path('app/backup-temp'),

        'password' => env('BACKUP_ARCHIVE_PASSWORD'),

Then make sure the commands are set to run

        $schedule->command('backup:clean')
            ->environments('production')
            ->daily()->at('02:00');
        $schedule->command('backup:run')
            ->environments('production')
            ->daily()->at('02:30');
        $schedule->command('backup:monitor')
            ->environments('production')
            ->daily()->at('03:00');
