1、首先需要下载相应的类库，并把类库方法.\extends\org\下。点击下载
2、控制器内容：

<?php
namespace app\index\controller;

use think\Controller;

class Backup extends Controller
{
    //数据库备份
    public function index()
    {
        //获取操作内容：（备份/下载/还原/删除）数据库
        $type = input("type");
        //获取需要操作的数据库名字
        $name = input("name");
        $backup = new \org\Baksql(\think\Config::get("database"));
        switch ($type) {
            //备份
            case "backup":
                $info = $backup->backup();
                $this->success("$info", 'index/backup/bak');
                break;
            //下载
            case "dowonload":
                $info = $backup->downloadFile($name);
                $this->success("$info", 'index/backup/bak');
                break;
            //还原
            case "restore":
                $info = $backup->restore($name);
                $this->success("$info", 'index/backup/bak');
                break;
            //删除
            case "del":
                $info = $backup->delfilename($name);
                $this->success("$info", 'index/backup/bak');
                break;
            //如果没有操作，则查询已备份的所有数据库信息
            default:
                return $this->fetch("index", ["list" => array_reverse($sql->get_filelist())]);//将信息由新到老排序
        }
    }
}

3、视图中：

<div class="ibox-content">
    <div class="">
        <a class="btn btn-primary " href="{:url('index',['type'=>'backup'])}"onclick="return confirm('备份数据的时间较长，确定要备份所有数据吗?')"><i class="glyphicon glyphicon-plus"></i> <span class="bold">添加备份</span></a>
    </div>
    <table class="table table-striped table-bordered table-hover dataTables-example"  style="text-align: center">
        <thead>
        <tr>
            <td>序号</td>
            <td>备份名称</td>
            <td>备份时间</td>
            <td>备份大小</td>
            <td>操作</td>
        </tr>
        </thead>
        <tbody>
        {volist name="list" id="vo"}
        <tr class="gradeX" >
            <td>{$key+1}</td>
            <td>{$vo.name}</td>
            <td>{$vo.time}</td>
            <td>{$vo.size}</td>
            <td width="25%">
                <a  href="{:url('bak',['type'=>'dowonload','name'=>$vo.name])}" class="btn btn-success "><i class="glyphicon glyphicon-download-alt"></i> <span class="bold">下载</span></a>
                <a  href="{:url('bak',['type'=>'restore','name'=>$vo.name])}" class="btn btn-info " onclick="return confirm('备份还原后仅会显示当前备份的数据库的信息，您确定还原备份吗 ?')"><i class="glyphicon glyphicon-repeat"></i> <span class="bold">还原</span></a>
                <a  href="{:url('bak',['type'=>'del','name'=>$vo.name])}"  class="btn btn-warning" onclick="return confirm('数据库备份一旦删除不可找回，您确定操作吗?')"><i class="fa fa-warning"></i> <span class="bold">删除</span></a>
            </td>
        </tr>
        {/volist}
        </tbody>
    </table>
</div>
