2014-04-29 20:13:27 avmossvss Error <0000>: The back-end client SQLBACKEND will be dropped later in the process.
2014-04-29 20:16:27 avmossvss Error <0000>: The back-end plug-in on client SQLBACKEND (10.1.1.1) terminated with errorcode 10019: Externally cancelled by Administrator.

Cause
後端資料庫伺服器上的 SQL 維護作業要麼與前端用戶端上的 SharePoint 備份同時啟動,要麼重疊。這些衝突的備份工作會導致其中一個或兩個工作失敗。雖然 SharePoint 備份在前端用戶端上啟動,但該前端用戶端會向每個後端用戶端發送子工作順序以備份 SharePoint 資料庫。如果另一個程序鎖定 SharePoint 資料庫,則 SharePoint 附掛程式無法備份後端用戶端上的資料庫。
SharePoint 場中的後端用戶端註冊到與前端用戶端不同的 Avamar 網格也可能導致類似的錯誤。
Resolution
將 SQL 維護或 Avamar SharePoint 備份的排定工作重新排列至不同的時間範圍,以避免它們重疊。
如果 SharePoint 場中的伺服器已註冊到不同的 Avamar 格線,請將所有伺服器重新註冊到相同的 Avamar 格線。若為同盟備份 (SharePoint、Exchange、SQL AlwaysOn),不支援將 Windows 用戶端註冊至不同的 Avamar 格線。
