avhypervvss Error : Failed to backup Virtual Machine 'SCVMM Avamar Resources'


從次要節點 C：\Program Files\avs\ 目錄內的記錄中，我們看到以下錯誤：

Cause

啟用工作階段安全性時，可能會因為 SSL 憑證錯誤而發生隨機的 Hyper-V 備份失敗。

從 Avamar 伺服器收到的私密金鑰無效。用戶端 Avagent 服務會傳送 IPv6 localhost （：：1） 作為分頁位址。此 IPv6 位址是環回位址，屬於主機名稱清單的一部分，但 MC 服務似乎僅儲存 IPV4 位址。

Resolution

有兩種因應措施可解決此問題：

1） 刪除 C：\Program Files\avs\etc 目錄中的檔案，然後在該節點上重新啟動 Backup Agent 服務。

2） 在次要節點的 C：Program Files\avs\var 目錄中建立 avagent.cmd 檔案，並新增下列旗標：

--ipupdateinterval=43200
--addr-family=4
-netbind=<<IP address that can access the Avamar server>>

範例：

--ipupdateinterval=43200
--addr-family=4
-netbind=192.168.1.1

保存檔，然後在 services.msc 控制台中重新啟動備份代理服務以使更改生效。
