oracle数据库的定时备份：导出压缩归类-优快云博客

本文介绍了一种通过命令行工具实现的自动化数据库备份方案，包括定时导出、自动压缩及按月归档等步骤。该方案利用了计划任务进行定时操作，并采用WinRAR进行文件压缩，最后将备份文件按月存储。

目标：

定时导出：利用计划任务
自动压缩：使用命令行的rar
自动按月存储：利用cmd

代码：

Cmd代码

@echo一定要进入指定路径,否则运行不正常

@setuserid=%owner%/erp_beijing_exp@dbsvr

@echo欢迎使用自动导库程序
@echo开始执行
@echo进入目录:%bk_path%

MKDIR %bk_path%/%THE_MONTH%
MOVE %bk_path%/*%THE_DATE%*.* %bk_path%/%THE_MONTH%
exit

遇到的问题和解决：

文件名中：小时在10点之前为“ X”有个空格导致文件名出问题，解决set MY_HOUR=%time:~0,2%
Cmd代码
1. if"%time:~0,1%"==""setMY_HOUR=0%time:~1,1%
```
if "%time:~0,1%"==" " set MY_HOUR=0%time:~1,1%
```
