我每晚都会在 510 个不同的文件(总是相同的文件)上收到以下警告消息:
警告:无法读取“[在此处插入文件名]”的部分内容。备份数据已损坏或不完整。此文件无法正确恢复。
我正在运行 SBS 2003,并且备份正在写入外部 USB 硬盘。
一些相关信息:
- 这个问题已在 3 个不同的外部硬盘上重现。这不太可能是存储介质的问题。
- 该问题已出现至少 2 个月。
- 在驱动器 vssadmin 列表编写器(在命令提示符下)上运行 chkdsk 后问题仍然存在,没有列出任何编写器上的错误。
- 备份硬盘上创建了 .bkf 文件。除了有警告的文件外,我可以成功恢复所有文件。有警告的文件可以恢复,但已损坏,即无法打开(原始文件可以打开)。
- 过去备份已成功完成。
- 我最近更换了硬盘,因为旧的 500GB 硬盘已接近容量上限(因此备份失败)。我使用的新硬盘是 4TB。但这个问题在旧硬盘和新硬盘上都出现了。
- 服务器还存在另一个问题,即其操作系统分区已达到容量上限,这导致了一系列问题。通过将 Exchange 数据库移至数据分区,解决了该问题。操作系统分区上的备份始终成功。产生错误的是数据分区。我怀疑该问题与服务器操作系统分区上的存储空间不足有关,因为该问题大约在同一时间(不到两个月前)开始出现。

这是昨晚备份的日志。我省略了所有错误消息,只留下一条通用消息。它们都一样,但一共有 510 条。
