为什么当有大量可用磁盘空间时，SharePoint 会声称没有足够的磁盘空间进行备份？

我正在尝试运行以下命令：

Backup-SPFarm -Directory E:\Backups -BackupMethod full -Verbose

但是它错误地指出磁盘空间不足...备份大小约为 1.8Gb，我有 27.52GB 的可用空间，那么为什么它认为我需要 30Gb？

VERBOSE: Leaving BeginProcessing Method of Backup-SPFarm.
VERBOSE: Performing operation "Backup-SPFarm" on Target "SHAREPOINTSERV".
Backup-SPFarm : There is not enough disk space. Free additional space on your h
ard disk and then try again. Approximate amount of space needed: 30.12 GB. Amou
nt of space free on disk: 27.52 GB.

该问题是由于 SharePoint_Config 日志文件太大 - 在我的情况下大约为 30Gb！

我发现这篇博客文章指向这里。

希望它有所帮助（我没有测试它 - 我将恢复模型更改为简单（运行完整备份后）然后缩小日志文件并将其改回完整 - 我怀疑下个月它会再次回到 30Gb？！？。我讨厌 sharepoint。
