### 配置文件

[](#配置文件)

```
$config=array(
    'path'     => './Data/',//数据库备份路径
    'part'     => 20971520,//数据库备份卷大小
    'compress' => 0,//数据库备份文件是否启用压缩 0不压缩 1 压缩
    'level'    => 9 //数据库备份文件压缩级别 1普通 4 一般  9最高
);

```

### 实例化

[](#实例化)

```
 $Backup= new Backup($config);

### 文件命名规则，请严格遵守（温馨提示）

[](#文件命名规则请严格遵守温馨提示)

```

### 备份文件列表

[](#备份文件列表)

```

### 备份表-单表备份

[](#备份表-单表备份)

 $table="数据库表1";
 $start= $Backup->setFile($file)->backup($table, 0);
 当$start返回0的时候就表示备份成功

```

### 备份表-多表备份

[](#备份表-多表备份)

```
 $tables=array();
 $file=['name'=>date('Ymd-His'),'part'=>1]

### 优化表

[](#优化表)

```
    $Backup->optimize($tables)

### 大数据备份采取措施1

[](#大数据备份采取措施1)

```
如果备份数据比较大的情况下，需要修改如下参数
//默认php代码能够申请到的最大内存字节数就是134217728 bytes，如果代码执行的时候再需要更多的内存,根据情况定义指定字节数
memory_limit = 1024M
//默认php代码申请到的超时时间是20s，如果代码执行需要更长的时间，根据代码执行的超时时间定义版本运行超时时间
max_execution_time =1000

```

### 大数据备份采取措施2

[](#大数据备份采取措施2)

```
    自由设置超时时间。支持连贯操作，该方法主要使用在表备份和还原中，防止备份还原和备份不完整
    //备份
    $time=0//表示不限制超时时间，直到程序结束，(慎用)
    $Backup->setTimeout($time)->setFile($file)->backup($tables[$id], 0);
    //还原
    $Backup->setTimeout($time)->setFile($file)->import($start);

```
