备份作业已完成,但出现警告Backup jobs completed with warning
当 MARS 代理在备份过程中循环访问文件和文件夹时,可能会遇到各种情况,这些情况可能会导致备份标记为已完成,但出现警告。When the MARS agent iterates over files and folders during backup, it might encounter various conditions that can cause the backup to be marked as completed with warnings. 在这些情况下,作业显示为已完成,但出现警告。During these conditions, a job shows as completed with warnings. 这样是可以的,但这意味着至少有一个文件未能备份成功。That's fine, but it means that at least one file wasn't able to be backed up. 即作业跳过了该文件,但备份了数据源中的所有其他相关文件。So the job skipped that file, but backed up all other files in question on the data source.
可能导致备份跳过文件的情况包括:Conditions that can cause the backups to skip files include:
- 不受支持的文件属性(例如,OneDrive 文件夹中不支持压缩流和重新分析点)。Unsupported file attributes (for example: in a OneDrive folder, Compressed stream, reparse points). 有关完整列表,请参阅支持矩阵。For the complete list, refer to the support matrix.
- 文件系统问题A file system issue
- 其他进程干扰(例如,包含文件句柄的防病毒软件可能会阻止 MARS 代理访问文件)Another process interfering (for example: antivirus software holding handles on files can prevent the MARS agent from accessing the files)
- 应用程序锁定的文件Files locked by an application
备份服务会将日志文件中的这些文件标记为失败,采用以下命名约定:C:\Program Files\Azure Recovery Service Agent\temp 文件夹下的 LastBackupFailedFilesxxxx.txt 。The backup service will mark these files as failed in the log file, with the following naming convention: LastBackupFailedFilesxxxx.txt under the C:\Program Files\Azure Recovery Service Agent\temp folder.
若要解决此问题,请查看日志文件以了解问题的性质:To resolve the issue, review the log file to understand the nature of the issue:

排查缓存问题Troubleshoot Cache problems
如果缓存文件夹(也称为 scratch 文件夹)配置不正确、缺少必备项或具有受限访问权限,则备份操作可能会失败。Backup operation may fail if the cache folder (also referred as scratch folder) is incorrectly configured, missing prerequisites or has restricted access.
先决条件Prerequisites
要使 MARS 代理操作成功,缓存文件夹需要符合以下要求:For MARS agent operations to succeed the cache folder needs to adhere to the following requirements:
- 确保暂存文件夹位置有 5% 到 10% 的可用卷空间Ensure 5% to 10% free volume space is available in the scratch folder location
- 确保暂存文件夹位置有效且可访问Ensure scratch folder location is valid and accessible
- 确保缓存文件夹上的文件属性受支持Ensure file attributes on the cache folder are supported
- 确保分配的影子副本存储空间足以支持备份过程Ensure the allocated shadow copy storage space is sufficient for backup process
- 确保没有其他进程(例如防病毒软件)限制对缓存文件夹的访问Ensure there are no other processes (ex. anti-virus software) restricting access to cache folder
增加影子副本存储Increase shadow copy storage
如果用于保护数据源的影子副本存储空间不足,则备份操作可能会失败。Backup operations could fail if there isn't sufficient shadow copy storage space that's required to protect the data source. 若要解决此问题,请使用 vssadmin 增加受保护卷上的影子副本存储空间,如下所示:To resolve this issue, increase the shadow copy storage space on the protected volume using vssadmin as shown below:
- 在提升的命令提示符下检查当前的影子存储空间:Check the current shadow storage space from the elevated command prompt:
vssadmin List ShadowStorage /For=[Volume letter]:
- 使用以下命令增加影子存储空间:Increase the shadow storage space using the following command:
vssadmin Resize ShadowStorage /On=[Volume letter]: /For=[Volume letter]: /Maxsize=[size]
阻止访问缓存文件夹的其他进程或防病毒软件Another process or antivirus software blocking access to cache folder
如果你在服务器上安装了防病毒软件,请将所需的排除规则添加到这些文件和文件夹的防病毒扫描项中:If you have antivirus software installed on the server, add necessary exclusion rules to the antivirus scan for these files and folders:
- scratch 文件夹。The scratch folder. 其默认位置为
C:\Program Files\Azure Recovery Services Agent\Scratch
Its default location isC:\Program Files\Azure Recovery Services Agent\Scratch
C:\Program Files\Azure Recovery Services Agent\Bin
