适用场景

  • ONTAP 9
  • CIFS/SMB
  • Coheesity备份应用程序

问题描述

  • 还原过程失败
  • 在还原过程中、协力应用程序会从原始文件创建一个临时文件、然后写入该临时文件、并将该临时文件重命名为原始文件名。然后、它将更新原始文件的元数据时间戳和NTFS ACL。
  • 此时、协力士应用程序尝试通过发送open/setinfo调用来更新已还原的文件元数据(时间戳和DACL)
  • 更新元数据时、应用程序请求了写入属性/读取控制/写入所有者等访问权限
  • ONTAP对用于更新文件元数据的open/setinfo调用返回"access denied"。还原文件的时间戳是临时文件时间戳、而不是原始文件时间戳
示例:
  • 原始名称:<name>.xlsm
  • 还原名称: __ch__2735304_0_tlsm <name>
