Avamar 虚拟机映像恢复在显示任何进度字节之前失败

• 虚拟机映像恢复在显示任何进度字节之前失败，我们可以从活动日志中看到以下错误消息：

• 上面提到的错误意味着代理尝试从 Data Domain 检索虚拟机元数据，但无法与其通信。
• 这导致发送到 vCenter 的代理请求无效，因此虚拟机创建步骤失败。 

• 启动恢复时，Data Domain 上的加密模式会保持为“默认”值，即使在 Avamar 和 Data Domain 上进行备份时将加密强度设置为“High”也是如此。

• 要解决此问题，请在启动恢复时执行以下步骤：

1-确保在 Avamar 上将加密强度设置为“High”，如下所示：

2-然后，单击“More Options”，在 Data Domain 上将加密设置为“High”，如下所示：

• 映像恢复应能够正常完成。
