2020-03-31 23:18:44 avhypervvss Error <41659>: Backup did not complete successfully 

在次要節點上,我們可能會在記錄中看到這些錯誤 (通常在 C:\Program Files\avs\var 目錄中):

Cause

Hyper-V 彈性變更追蹤 (RCT) 範圍位於傳送至 Data Domain 的權杖要求中。如果 RCT 範圍過多,DDR 權杖要求會失敗。
avagent 軟體修正會停用在權杖要求中包含 RCT 範圍的功能,因為這不是必要的。

Resolution

以解決此問題。
  • 將 Avamar Server 升級至 19.4.100-124 版或更新版本
  • 此修正已納入 Avamar 版本 19.4 及更新版本的軟體版本中

Additional Information

即使將 avagent 軟體修正套用至所有叢集節點,Hyper-V 備份仍可能會失敗。如果是這種情況,則其他問題可能會導致問題。這些問題,例如 Java 程序停止回應,或 Avamar Utility Node 上的 DDRmaintlog 轉換失敗,都需要 Avamar 支援調查。
