.net Powershell压缩。Zipfile错误

在Powershell中运行脚本时收到错误。该脚本在一个目录中查找两个特定文件夹（一个约13GB，另一个1.5GB），并在zip文件名后附加日期/时间字符串对其进行压缩。它已经无误运行了一年多。直到平安夜。通常仅在一个文件夹上接收错误，而另一个文件夹则正常处理。尽管脚本按特定顺序处理文件夹，但在哪个文件夹上发生错误似乎是随机的。该代码自一年前投入生产以来一直没有改变

我的错误

使用“4”参数调用“CreateFromDirectory”时出现异常：“数据错误（循环冗余检查）。”

您似乎正在正在压缩的文件夹中创建zipfile。尝试将其移到

$sourceFolder

tree@Eris正在压缩的文件夹是G:\MSSQL\u Backups\Alpha，文件Alpha\u 201301113123022（基于日期时间）正在压缩到G:\MSSQL\u Backups。是否尝试了其他压缩方法？
