XenServer无法备份：

我有这个问题一年又一年，我想我应该终于发布一些东西。

当在XenServer 6.5 SP1的三个主机池上进行服务器 – >备份时，出现“无法从传输连接读取数据：连接尝试失败，因为连接方在一段时间后没有正确响应，或者build立的连接失败因为连接的主机没有响应。“

谷歌search这并没有得到我太多，除了一个较旧的职位没有一个直接的解决scheme：

• Powershell和par2命令行
• 如何还原Windows Server中的特定系统状态项
• 监视位级存储的变化
• find/更新与档案支持？ （tar.gz等）
• Azure：Linux VM还原不起作用

发生此错误时，我不会丢失连接池。 错误发生在多个工作站上，并在两个不同的池上。 在最近的情况下，我能够获得池主服务器的备份，但成员服务器失败并出现此错误。
