我正在使用adityasatrio的批处理文件来备份本地MySQL数据库,并且希望仅保留30个最新的备份文件。在此示例中使用root:root。
@echo off set dbUser=root set dbPassword=root set backupDir="D:\MySQLDumps\dbs\" set mysqldump="C:\wamp\bin\mysql\mysql5.6.17\bin\mysqldump.exe" set mysqlDataDir="C:\wamp\bin\mysql\mysql5.6.17\data" set zip="C:\Program Files\7-Zip\7z.exe" :: get date for /F "tokens=2-4 delims=/ " %%i in ('date /t') do ( set yy=%%i set mon=%%j set dd=%%k ) :: get time for /F "tokens=5-8 delims=:. " %%i in ('echo.^| time ^| find "current" ') do ( set hh=%%i set min=%%j ) echo dirName=%yy%%mon%%dd%_%hh%%min% set dirName=%yy%%mon%%dd%_%hh%%min% :: switch to the "data" folder pushd %mysqlDataDir% :: iterate over the folder structure in the "data" folder to get the databases for /d %%f in (*) do ( if not exist %backupDir%\%dirName%\ ( mkdir %backupDir%\%dirName% ) %mysqldump% --host="localhost" --user=%dbUser% --password=%dbPassword% --single-transaction --add-drop-table --databases %%f > %backupDir%\%dirName%\%%f.sql %zip% a -tgzip %backupDir%\%dirName%\%%f.sql.gz %backupDir%\%dirName%\%%f.sql del %backupDir%\%dirName%\%%f.sql ) popd
现在,我对以下问题进行了很好的了解:
批处理文件以删除超过N天的文件
https://serverfault.com/questions/49614/delete-files-older-than-x- days
将7个最新文件保存在一个文件夹中的批处理文件
Windows批处理文件仅保留最后30个文件
现在想知道我是否可以简单地添加(https://stackoverflow.com/a/14267137/1010918)
for /f "skip=30 delims=" %%A in ('dir /a:-d /b /o:-d /t:c *.sql ^2^>nul') do if exist "%%~fA" echo "%%~fA"
(是的,我稍后将echo更改为del,但首先我想看看会发生什么)
或(https://stackoverflow.com/a/13368077)
for /f "skip=30 eol=: delims=" %%F in ('dir /b /o-d *.sql') do @del "%%F"
在批处理文件的末尾,就在
del %backupDir%\%dirName%\%%f.sql
做到这一点?
我以前从未做过此事,但已经搜索了MySQL数据库的自动本地备份应用程序/ php脚本/ mysqldump命令/ etc,甚至尝试使用Workbench只是发现在社区版中无法设置任何计划(感谢Oracle) 。
所有其他应用程序都需要有人打开该应用程序并单击“立即运行”,或者希望您为设置时间表付费(不用了,谢谢)。
我认为可以使用Windows 7及更高版本计算机上的工具来完成此操作。请帮助我将此功能添加到脚本中,太好了,谢谢。
编辑1:
当添加引号命令时,什么也不会发生。创建的备份目录也仅显示时间,而不显示年,月和日。做进一步的研究以找出原因。有任何想法吗?
此评论删除所有(除X个最新文件夹外)谈论删除5个最新文件夹,尽管当我像这样使用它时
for /f "skip=2 delims=" %%a in ('dir %backupDir%\%dirName% /o-d /b') do rd /S /Q "%backupDir%\%dirName%\%%a"
错误如下。
The system cannot find the file specified. The system cannot find the path specified.
edit2: 下面是使用@foxidrive帮助设置我喜欢的文件夹名称的代码,但最后一点是,尝试仅保留3个最新文件夹(仅用于测试目的3个),并删除其中的其余文件夹backupDir似乎无法解决。
感谢您的任何帮助。

在上面的@foxidrive的帮助下,我设法获得了想要的文件夹日期,它们是YYYY-MM-DD HH-MIN-SEC。
由于adityasatrio的MySQL Backup Batch Script,在这些文件夹中存储了gzip压缩的.sql数据库。
借助此答案中的@ Magoo,https://stackoverflow.com/a/17521693/1010918设法删除了所有文件夹(nameDir), 同时保留 了最新的N个文件夹(nameDir),并且也 没有 触摸任何可能在目录(backupDir)中。
这是完整的工作脚本。
随意删除任何出现pause并和echo对 不 上有什么命令提示符里面去。
pause
echo
此外,将其添加到Windows Task Scheduler中,您将获得一个针对使用MySQL数据库的本地开发环境的可靠备份解决方案。
请感谢帮助我完成此任务的人员。没有你们,我不得不只使用昂贵的Windows应用程序来本地保存MySQL数据库。
(..以及下一个技巧,如果备份.sql文件时出现错误,我们将通过电子邮件将错误日志发送给自己。.但这又是另一个问题和故事。.)
