除了提供灾难恢复功能外,两个配对的池彼此用作对方的备份注册器。In addition to providing disaster recovery ability, two paired pools serve as the backup Registrars for each other. 在 Lync Server 2013 中,前端池之间的备份注册器关系始终为1:1 和互惠。In Lync Server 2013, backup Registrar relationships between Front End pools are always 1:1 and reciprocal. 这意味着,如果 P1 是 P2 的备份,则 P2 必须为 P1 的备份,两者均不能成为任何其他前端池的备份。This means that if P1 is the backup for P2, then P2 must be the backup for P1, and neither can be the backup for any other Front End pool. 这是 Lync Server 2010 的更改,在这种情况下,前端池备份关系可能是多到一。This is a change from Lync Server 2010, in which Front End pool backup relationships could be many to one.

尽管两个前端池之间的备份关系必须为1:1 和对称关系,但每个前端池仍可以是任意数量的 Survivable 分支设备的备份注册器,就像在 Lync Server 2010 中一样。Even though backup relationships between two Front End pools must be 1:1 and symmetrical, each Front End pool can still also be the backup registrar for any number of Survivable Branch Appliances, just as in Lync Server 2010.

请注意,Lync Server 2013 不会将灾难恢复支持扩展到驻留在 Survivable 分支设备上的用户。Note that Lync Server 2013 does not extend disaster recovery support to users homed on a Survivable Branch Appliance. 如果前端池用作 Survivable 分支设备的备份,则登录到 Survivable 分支设备的用户将进入恢复模式,即使在前端池上驻留的用户故障转移到备份前端池之后也是如此。If a Front End pool that serves as the backup for a Survivable Branch Appliance goes down, users signed into the Survivable Branch Appliance fall into resiliency mode even after users homed on the Front End pool are failed over to the backup Front End pool.
