如何验证备份是否无错完成

 

上一次修改主题: 2005-05-09

此主题说明如何验证备份是否无错完成。

  1. 在备份作业完成后,请确保“备份进度”对话框中显示“状态:已完成”。

    29646049-d4f5-4c1e-a636-60d2bcf3f3ae
  2. 单击“报告”查看备份日志文件,以确定在备份过程中是否发生了任何错误。

    默认情况下,日志文件设置为仅记录所执行的备份作业的摘要。如果在备份过程中收到错误消息,并且需要有关故障的更详细数据,可以再次执行备份并使用详细日志记录。然后可以搜索日志文件以确切了解所发生的情况。有关启用详细日志记录的详细信息,请参阅选择“备份”的默认设置

    下面是正确完成的 Windows 备份(其中包括 Exchange 文件夹)的备份日志示例:

  3. 检查备份日志文件中是否有错误。请确保备份日志文件中没有错误。

    note注意:
    每个备份作业都在该日志文件中添加信息。可能必须滚动到日志文件的底部,才能找到与最新的备份有关的信息。
  4. 如果对此备份作业启用了验证,可以查看日志文件的 Verify Status 部分,以便通过查看 Different: 来查看备份中的哪些文件(如果有)与磁盘上的原始文件不匹配(Different 为日志文件中的行)。请注意某些文件的变化是有规律的,并且文件之间的差异并不一定总是意味着有问题。

  5. 关闭日志文件和“备份进度”对话框。

  6. 单击“开始”,指向“所有程序”,再指向“管理工具”,然后单击“事件查看器”。

  7. 在事件查看器的控制台树中,单击“应用程序”。在详细信息窗格中,确保来源为“NTBackup”或“ESE”(可扩展存储引擎)的应用程序事件日志中没有报告“错误”条目。这些错误表示备份未成功完成。

    important重要提示:
    当备份 Exchange 数据时,此步骤至关重要。出现的某些错误仅显示在应用程序事件日志中。备份 Exchange 时,请不要仅依赖备份日志。
    note注意:
    要加快搜索的速度,请查看表示备份和验证过程开始和完成的事件。然后检查在此期间出现的任何事件。事件 8000 表示备份开始,事件 8019 表示备份结束。
  8. 查找错误后关闭事件查看器。
