Recovering from Failure Using SCR
Switching from an SCR source to an SCR target server is called activation It is important to note that SCR is not designed for temporary server outages The right approach to protect from such temporary server outages is by using failover clustering either CCR or SCC SCR should be a second line of defense, to be used when there is significant failure, and other recovery mechanisms, such as restoring from backup, will take too long In an SCC scenario, if the shared storage on which Exchange storage groups reside fails, or a database is corrupt, SCR activation can be the next line of defense In a CCR scenario, if both the cluster nodes fail or the databases on both nodes becomes corrupt, SCR can be the next line of defense In a site failure scenario, SCR provides the important capability of getting users up and running in the shortest amount of time, compared to recovering from a backup There are two paths you can take to activate an SCR target The first one involves recovering a server or a CMS depending on whether the source is a CMS or a standalone server The second one involves using Database Portability to mount the replica database to the SCR target server, followed by moving users to the SCR target using the with the Move-Mailbox command ConfigurationOnly switch The starting point for both methods is to disable SCR and make the SCR replica on the target server ready for mounting This is done using the following command:
Restore-StorageGroupCopy "SourceServer\Storage Group Name" StandbyMachine "SCR Target Server Name"
This command ensures all transaction logs from the source storage group have been copied to the replica on the target server Attempts are made to copy any missing files to the replica However, if the source server is unavailable, the command should be used with the Force switch appended
The Path to Recovery
When planning to use SCR, you need to consider recovery scenarios and choose a recovery path from the two choices outlined earlier

TIP Although SCR allows using a CMS (SCC or CCR) as the source and a standalone server as a
target, as well as the other way around, such combinations eliminate one path of recovery, or at least make it considerably more time consuming For instance, a source that is clustered cannot be recovered using /RecoverServer if the target is a standalone server It makes sense to use a clustered target for a clustered source to be able to use /RecoverCMS instead You do not need additional servers in a typical two-node configuration to use a clustered target a single node suffices The only difference in cost is the Enterprise edition of Windows Server that failover clustering requires (Alternatively, if the target for a clustered source is a standalone server, you can uninstall Exchange, install and configure the Cluster Service, and then use /RecoverCMS However, as stated earlier, this makes recovery more time consuming) Similarly, if the source is a standalone Exchange server, it is logical to expect the target be a standalone server as well, although SCR allows the use of a clustered target in this scenario
In the case of a failure of a source server or CMS with multiple storage groups being replicated to an SCR target, recovering a CMS provides the fastest path If the source and target servers are clustered, Exchange is already installed on the SCR target cluster, but no CMS has been created Using Setup /RecoverCMS creates the CMS on the target
TIP It may be desirable to locate the SCR target on a cluster, even if it consists of a single node This
provides the ability to use Setup /RecoverCMS on an already existing Exchange installation for a speedy activation of the standby cluster
When /RecoverServer is used, Exchange is installed on the server, which gets the identity of the server being recovered In other words, the server gets the same server name and is associated with the same msExchExchangeServer object in the Configuration container Obviously, this is not possible on the SCR target server without uninstalling Exchange Server from it it already has an identity (unlike a cluster with no CMS created) In this case, Exchange Server needs to be uninstalled and reinstalled with the /RecoverServer option If the failure is limited to a storage group or two (for instance, due to database corruption or the loss of a disk volume), it is easier to use Database Portability and point the affected users to the SCR target using the move-mailbox command
