NetWorker VMware Protection 整合是透過 vProxy 裝置進行設定。備份已成功運行一段時間，並且它們開始間歇性失敗，並顯示”
VMware 保護原則備份動作記錄中一個 VM 故障的範例：
The VM backup request is not valid.」備份動作記錄顯示它會持續重試一小時，以直接儲存至 NetWorker 儲存節點，直到失敗並顯示訊息。

Cause
NetWorker 儲存節點
nsrmmd 在工作流程執行期間，程序或目標 Data Domain 超載。Data Domain 讀取串流用盡使 VMware 保護原則備份動作無法啟動備份工作階段。Resolution
錯開環境中的傳統用戶端和 VMware 工作流程，以在一天中分散目標 Data Domain 的負載。
