Avamar：被动节点的 Exchange VSS DAG 备份错误 41466 “所选目标列表为空”

Exchange DAG 代理备份失败，并显示类似于以下内容的错误：

avexvss Info <41087>: Excluding passive database 'DB1' from backup because only store (active) writer has been selected.
avexvss Info <41087>: Excluding passive database 'DB2' from backup because only store (active) writer has been selected.

avexvss Error <41466>: List of selected targets is empty. Unable to complete backup.
avexvss Error <13077>: Unable to complete backup

将数据集配置为仅备份 Exchange 数据库的活动拷贝。有问题的 Exchange 节点仅包含被动拷贝。

由于激活到与代理节点不同的 Avamar 网格的辅助 Exchange 节点，也可能会出现问题。这不是 Avamar Exchange DAG 备份（代理和联合）支持的配置。

将“Set when backup occurred on clustered or DAG systems”字段的值更改为“Always”。此选项指示插件在所有 Exchange DAG 节点上备份 Exchange 数据库的主动和被动拷贝。

将辅助 DAG 节点重新注册到与代理节点相同的 Avamar 网格。
