Síntomas

NetWorker VMware Protection (NVP) 集成已通过 vProxy 设备进行配置。备份间歇性失败，并显示 resource not found NetWorker Management Console 中的消息。虚拟机的后续备份将完成，但可能会影响其他虚拟机。

虚拟机备份日志和 NetWorker Management Console 消息显示：

Causa

NetWorker 服务器会持续检查备份会话的状态，并在备份会话完成后请求日志。在 NetWorker 服务器在几分钟内未请求更新后，vProxy 会完成备份并使会话保持老化。随着会话老化，vProxy 无法再为 NetWorker 服务器提供状态更新或日志，并且失败并显示 resource not found 错误，请参阅概述的步骤以帮助解决该问题。NetWorker 服务器状态请求延迟通常是由于 NetWorker 存储节点与 Data Domain 通信之间的高延迟造成的。

Resolución

在备份执行期间，NetWorker 存储节点到 Data Domain 的延迟应降至 50 毫秒以下。此指导准则记录在《 Dell NetWorker 性能优化规划指南》的“TCP 窗口大小和网络延迟注意事项”部分中。如果无法降低延迟，则建议在远程站点配置 NetWorker 存储节点以管理 Data Domain 设备。

以下文章详细介绍了如何执行一些网络故障处理：NetWorker：如何对网络相关问题进行故障处理。

以上文章详细介绍了如何从 NetWorker 存储节点和 Data Domain 执行带时间戳的 ping。确认时区匹配，让 ping作在后台运行并输出到文件。重现备份问题时，在发现备份问题的时间段内检查 ping 输出文件的时间范围是否存在高延迟。
