think-backup

【特别鸣谢】https://github.com/tp5er/tp5-databackup

think-backup扩展是在https://github.com/tp5er/tp5-databackup的基础上,做了部分调整。 目前可以满足个人需求。

主要功能有:

  • 数据表的备份(单表备份/多表备份)
  • 数据备份的还原
  • 数据表的优化(支持多表)
  • 数据表的修复(支持多表)
  • 备份文件的下载
  • 清空表(支持多表清空)

使用composer进行安装

     composer require yifeng/think-backup

使用composer update进行安装

    "require": {
        "yifeng/think-backup": "1.*"
    },

引入类文件

use think\Backup;

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

 $Backup= new Backup($config);

文件命名规则,请严格遵守(温馨提示)

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

数据类表列表

$Backup->dataList();

备份文件列表

$Backup->fileList();

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

 $tables=array();
 $file=['name'=>date('Ymd-His'),'part'=>1]
 $start=1;
 foreach ($tables as $table){
    $start= $Backup->setFile($file)->backup($table, 0);
 }
 当$start返回0的时候就表示备份成功

导入表

 $start=0;
 $start= $Backup->import($start);

删除备份文件

    $Backup->delFile($time);

下载备份文件

    $Backup->downloadFile($time);

修复表

    $Backup->repair($tables)

优化表

    $Backup->optimize($tables)

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

    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);

特别感谢
