Last modified: April 18, 2016

Applies to: SharePoint Foundation 2013 | SharePoint Server 2013

This article describes the supported high availability and disaster recovery options for SharePoint 2013 databases. For detailed information about these databases, such as size and supported backup and recovery tools, see Database types and descriptions (SharePoint 2013). You can also view or download a model (Databases that support SharePoint 2013) of these databases on the Database types and descriptions (SharePoint 2013) page.

In this article:

The scope of this article is the supported high availability and disaster recovery solutions for each SharePoint 2013 system and service application database. These solutions address the database level, instead of the database instance or database server level and include the following: database mirroring, database availability groups, and log shipping.

When you evaluate a high availability or a disaster recovery option for SharePoint, you must understand that not all of the options are supported by each SharePoint database. This is because of design requirements and feature characteristics.

This article identifies the supported option for each SharePoint database. These databases are grouped by SKU and then by feature.

The Configuration, the SharePoint Central Administration website Content, and Content databases are the databases that are automatically installed when you deploy any SharePoint 2013 edition.

The following tables provide the supported high availability and disaster recovery options for the SharePoint system databases.

SharePoint Server 2013 is built on SQL Server and uses the following SQL Server system databases: master, msdb, tempdb, and model. SQL Server provides a complete set of administrative tools that let users fully administer their system and manage all users and objects in a database. For more information about the SQL Server system databases, see System Databases.

You can only mirror user databases, put them in a SQL Server AlwaysOn availability group or log ship them. You can’t use these approaches to provide high availability or disaster recovery for the system databases.

The following SQL Server Reporting Services (SSRS) databases can be used as part of a SharePoint 2013 deployment:

  • Report Server Catalog (ReportingService_<GUID>) - Stores all report metadata including report definitions, report history and snapshots, and scheduling information.
Note Note

  When Report Server Catalog is used, report documents are stored in SharePoint content databases.

  • ReportServerTempDB (ReportingService_<GUID>_TempDB) - Stores all the temporary snapshots while reports are running.
  • Report Server Alerting (ReportingService_<GUID>_Alerting) - Stores all Data Alerts and runtime information.

A Reporting Services report server is a stateless server that stores application data, content, properties, and session information in two SQL Server relational databases. The best way to ensure the availability of Reporting Services functionality is to do the following:

  • Use the high availability features of the SQL Server Database Engine to maximize the uptime of the report server databases. If you configure a Database Engine instance to run in a failover cluster, you can select that instance when you create a report server database.
  • Use SQL Server AlwaysOn Availability Groups with the Reporting Services databases and for data sources where applicable.
  • Configure multiple report servers to run in a scale-out deployment, where all the servers share a single report server database. Deploying multiple report server instances on different servers can help increase the level of uninterrupted service.
