Symptoms

E:\ 備份失敗  執行數小時後,在 Windows 用戶端上執行磁碟機。備份其他磁碟機或 DR 儲存集沒有問題。
工作流日誌中的錯誤訊息:

--- Job Indications ---
read failed on \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy15\<file with path>: No such file or directory.

操作紀錄中的錯誤訊息 (/nsr/logs/policy/<policy>/<workflow>/<backup_xxx_logs>/xxx.log):

91579:save: Unrecoverable readfile error captured, backup will not complete.
127945:save: read failed on \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy15\<file with path>: No such file or directory

Cause

捲影複製在開始備份時建立,但在備份完成之前移除,原因是 volsnap 事件 .
Windows 系統事件記錄 ID 25。

The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time.  Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.

Windows 儲存控制器驅動程式和韌體未更新,而且在 NetWorker 備份期間,有另一個本機備份用於在 E:\ 磁碟機上執行。然而,在本機備份完成後更新驅動程式/韌體和變更 NetWorker 備份開始時間,無法解決問題。
 

Resolution

磁碟機大小約為 7 TB,並有 2.3 TB 的可用空間。卷影副本的存儲設置為 700GB。
將捲影複本儲存裝置增加至 1.2 TB 後,此問題已解決
