Install-CsMirrorDatabase

Associates a mirror database with a Skype for Business Server database. A database mirror enables you to simultaneously maintain two copies of a database, each copy residing on a different server. This cmdlet was introduced in Lync Server 2013.

Description

Mirror databases enable you to simultaneously maintain two copies of a database: when data is written to Database A, a copy of that data is also written to its mirror database. This provides the ability to instantly replace Database A should that database become unavailable: you can "failover" to the mirror database with minimal disruption to your users and with minimal data loss. After you have installed your primary databases you can then install and configure mirror databases by using the Install-CsMirrorDatabase cmdlet.

By default, the Install-CsMirrorDatabase cmdlet installs and configures mirror databases for all the Skype for Business Server databases housed on the specified server. However, you can use the DatabaseType or the ExcludeDatabaseList parameters to specify exactly which mirror databases should or should not be installed. DatabaseType enables you to specify only the databases that should be installed; ExcludeDatabaseList lets you specify the databases that should not be installed.

Skype for Business Server Control Panel: The functions carried out by the Install-CsMirrorDatabase cmdlet are not available in the Skype for Business Server Control Panel.

Examples

-------------------------- Example 1 --------------------------

Install-CsMirrorDatabase -ConfiguredDatabases -FileShare "\\atl-fs-001.litware.com\DbBackup" -SqlServerFqdn "atl-primary-001.litwareinc.com" -DropExisitingDatabasesOnMirror

The command shown in Example 1 installs any predefined database. The ConfiguredDatabases parameter causes the Install-CsMirrorDatabase cmdlet to use the current topology to determine which databases should be.
