sql server 2008新建好了发布订阅后，在每天自动同步完成后怎么删除发布数据库中快照文件

Posted 2023-04-13

即同步完成后怎么去自动删除D:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\repldata\unc文件夹中的文件。

可以写个批处理，在每天自动同步的时间后执行，删除快照文件。追问

请问有没有类似的文件可供参考，我的邮箱是[e-mail]。谢谢

追答

编辑一个文件名
比如xx.bat
内容为：

del 路径/文件名

然后保存
然后
系统工具——任务计划-〉添加任务计划-〉下一步-〉浏览到刚才编写的那个xx.bat

参考技术A 发布类型选择事务发布，旧快照会自动删除 参考技术B 这个就是用虚拟机做的追问

这个和虚拟机貌似没有半毛钱的关系啊！是数据库方便的。- -

参考技术C 会自动删除的。追问
