Symptoms

由於 SnapShotManager 作業，Avamar 映像備份或還原工作失敗/緩慢。

Cause

SnapShotManager 服務的背景：  

SnapshotManager 是在 Avamar 伺服器上運作的 Web 服務。在備份或還原作業期間，當 Avamar 代理執行快照作業 （建立、刪除或整合） 時，它會使用 SnapshotManager 服務。此方法可集中快照作業，讓快照作業能排入 Avamar 伺服器佇列，而非 vCenter。但是，這種集中式模型引入了潛在的瓶頸和服務依賴關係，可能需要禁用才能解決備份或還原問題。

若要檢查 SnapshotManager 狀態，請按照下列步驟操作：

如果已啟用 SnapshotManager，映像備份記錄會顯示下列資訊： 
avvcbimage Info <42215>: SnapshotManager: initializing at Avamarserver:443, vCenter vc6-avamar.example.com(root), datacenter(/Burlington), httpsTimeout_ms(3600000), maxDeleteRetries(-1)
avvcbimage Info <42191>: GET: curl_easy_getinfo succeeded with httpcode(200)
avvcbimage Info <44033>: AvSnapMgr::getData Succeeded httpCode: 200


 如果 SnapshotManager 已停用，映像備份記錄會顯示： 
 avvcbimage Info <40643>: NOT using SnapShot Manager - using proxy method of calling vSphere API functions.
 avvcbimage Info <18648>: The snapshot '' could not be removed.

Resolution

長期解決方案：
此問題將在未來的 Avamar 版本中解決。在未來的 Avamar 版本中，Avamar 代理將不會使用 SnapshotManager 服務。
 

如何在目前版本中停用 Snapshot Manager：

若要停用 SnapshotManager 服務，請使用以下兩種方法之一修改代理的avvcbimageAll.cmd：
 

使用 goav 的自動化方法：

1. 使用 KB Avamar 安裝 goav：Avamar：Goav 工具
