Sql server 2008 r2 SQL Server差异备份失败

我注意到我们的维护计划中存在差异备份故障。这似乎是尝试进行企业vault复制的结果，但目前无法确认。上一次完全备份是在下午5:00完成的，故障发生在晚上11:30

问题是，我似乎找不到这个新的完整备份，它是由12:30的差异备份创建的，作为它们的基础？有没有一种方法可以找到差异指向的基本文件？

一种方法是通过PowerShell脚本（在各种论坛上都可以轻松获得）自动执行此任务，您可以在其中为增量备份、完整备份和差异备份设置单独的参数。 我更喜欢的另一种方法是使用专用的备份软件设置来完成此任务。 早些时候，我让MS DPM管理SQL备份，它真的工作得非常出色。

我还尝试过Cloudberry备份SQL Server，它也是一种轻巧可靠的基于云的备份工具。

这与编程（本网站的全部内容）没有任何关系，但是对于DB管理层来说，这是一个离题的话题，属于投票表决。抱歉@marc_s。看来我不能这样做，因为我的声誉很好，如果你能帮忙的话，我很高兴它被移动了
