| 第一步: 
 添加provider复制代码$ composer require laravel-admin-ext/backup -vvv
 复制代码// config/app.php
'providers' => [
    // ...
    Spatie\Backup\BackupServiceProvider::class,
];
第二部
 
 复制代码php artisan admin:import backup
第三部:在数据库配置文件中加上如下代码(config/database.php)参照修改
 
 主要是dump备份路径位置复制代码'mysql' => [
    'driver'            => 'mysql',
    'host'              => env('DB_HOST', 'localhost'),
    'database'          => env('DB_DATABASE', 'forge'),
    'username'          => env('DB_USERNAME', 'forge'),
    'password'          => env('DB_PASSWORD', ''),
    'charset'           => 'utf8',
    'collation'         => 'utf8_unicode_ci',
    'prefix'            => '',
    'strict'            => false,
    'engine'            => null,
    'dump' => [
        'dump_binary_path' => '/path/to/directory/', // only the path, without `mysqldump` or `pg_dump`
        // 'dump_binary_path' => '/Applications/MAMP/Library/bin/', // works for MAMP on Mac OS
        // 'dump_binary_path' => '/opt/homebrew/bin/', // works for Laravel Valet on Mac OS
        'use_single_transaction',
        'timeout' => 60 * 5, // 5 minute timeout
        // 'exclude_tables' => ['table1', 'table2'],
        // 'add_extra_option' => '--optionname=optionvalue',
    ]
],
 第四部:发布配置文件
 
 第五步:config/bacpup.php内容如下:复制代码php artisan vendor:publish --provider="Spatie\Backup\BackupServiceProvider"
 复制代码return [
    'backup' => [
        /*

备份不能下载和删除,需要修改D:\WWW\syfw\vendor\laravel-admin-ext\backup\resources\views 里面的视图文件
