Database types and descriptions in SharePoint Server

APPLIES TO: yes-img-132013 yes-img-162016 yes-img-192019 yes-img-seSubscription Edition no-img-sopSharePoint in Microsoft 365

This article describes the databases that are installed for SharePoint Server. Each database description includes information about sizing and placement. For more information see Storage and SQL Server capacity planning and configuration (SharePoint Server).

Databases for SharePoint Server 2019 can be hosted in Microsoft SQL Server 2016 and Microsoft SQL Server 2017. Databases for SharePoint Server 2016 can be hosted in SQL Server 2014 Service Pack 1 (SP1) and SQL Server 2016. Databases for SharePoint Server 2013 can be hosted in SQL Server 2008 R2 with Service Pack 1 (SP1) or SQL Server 2012. For more information see System requirements for SharePoint Servers 2016 and 2019 and Hardware and software requirements for SharePoint 2013.

All database names that are listed in this article are automatically created when you run the SharePoint Products Configuration Wizard. You do not have to use these naming conventions. You can either specify your own database names when you create them or change the names after they are created. For more information, see Move or rename service application databases in SharePoint Server

The database sizes listed in this article are based on the following ranges.


Descriptor Size range
Very Small
Up to 100 megabyte (MB)
Small
1 gigabyte (GB) or less
Medium
Up to 100 GB
Large
Up to 1 terabyte
Extra-large
More than 1 terabyte

You can download the SharePoint Server 2016 database poster, as either a PDF or Visio file.

For a graphical overview of the databases that support SharePoint Server 2013, see Database model.

SharePoint Server system databases

The following databases are part of all SharePoint Server deployments. These databases are installed when any SharePoint Server edition is deployed. The Configuration, Central Administration Content, and Content databases are the three databases that are automatically installed when you deploy SharePoint Server.

Configuration

The configuration database contains data about the following:

  • SharePoint databases

  • Internet Information Services (IIS) web sites

  • Web applications

  • Trusted solutions

  • Web Part packages

  • Site templates

  • Web applications

  • Distributed Cache configuration objects

    The configuration database tracks the state of all servers in the farm that run the Distributed Cache service.

The configuration database also contains specific data for SharePoint Server farm settings, such as default quota settings and blocked file types.

Configuration database

Category Description
Default database name when it is installed with the SharePoint Products Configuration Wizard
SharePoint_Config
Location requirements
Must be co-located with the Central Administration database
General size information and growth factors
Small
Transaction log files that are stored in the configuration database are likely to become large. For more information, see Additional notes.
Read/write characteristics
Read-intensive
Recommended scaling method
Must scale-up because only one configuration database is supported per farm. (Significant growth is unlikely.)
Associated health rules
None
Supported backup tools
SharePoint Server backup and restore, SQL Server, and System Center Data Protection Manager. Backing up and restoring the configuration databases is special because of the transaction log. For more information, see Additional notes.
Default recovery model
Full. We recommend that you keep the configuration database on the full recovery model and take backups to truncate the log files.

Additional notes

Transaction log files. We recommend that you back up the transaction log for the configuration database regularly to force truncation. If you are using SQL Server Always On availability groups or database mirroring, you should also keep the database running in full recovery mode. For more information, see The Transaction Log (SQL Server).

Backup and Restore. The configuration database is backed up when you perform a SharePoint farm configuration and content backup. Note that some configuration settings from the database are exported and stored as XML file. When a farm is restored, the configuration database is not restored. Instead, the saved configuration settings are imported. The configuration database can be successfully backed up and restored by using SQL Server or other tools if the SharePoint farm is first taken offline.

Note

Many configuration settings are not saved during a farm configuration-only backup or restore. These configuration settings may include particular Web application settings, service application settings, and settings that are specific to the local server. These settings are saved during a farm content and configuration backup. But some of them, such as service application proxy settings, cannot be restored during a farm recovery. For information about what is saved during a configuration backup, see Back up farm configurations in SharePoint Server. For information about how to document and copy configuration settings that are not backed up, see Copy configuration settings between farms in SharePoint Server.

Central Administration content

The Central Administration content database is considered to be a configuration database. It stores all configuration data for the Central Administration site collection. If SQL Server Power Pivot for SharePoint Server 2016 is installed, the Central Administration content database also stores the Excel Online worksheets and Power Pivot data files used in the Power Pivot Management Dashboard.

Note

Power Pivot for SharePoint can only be installed on SharePoint Server 2016 when you use SQL Server 2016 CTP 3.1 or later as the database server.

For more information, download Deploying SQL Server 2016 PowerPivot and Power View in SharePoint 2016. For details about configuring and deploying business intelligence in a multiple server SharePoint Server 2016 farm, download Deploying SQL Server 2016 PowerPivot and Power View in a Multi-Tier SharePoint 2016 Farm.

Note

Excel Services and its associated business intelligence capabilities are no longer hosted on SharePoint Server 2016. Excel Services functionality is now part of Excel Online in Office Online Server (this is the next version of Office Web Apps Server), and SharePoint users can use the services from there. For more information, see Office Online Server and Configure Excel Online administrative settings.

If SQL Server 2012 Power Pivot for SharePoint 2013 is installed, the Central Administration content database also stores the Excel worksheets and Power Pivot data files used in the Power Pivot Management Dashboard. Note that Power Pivot for SharePoint 2013 can only be installed on SharePoint Server 2013.

Central Administration content database

Category Description
Default database name prefix when it is installed by using the SharePoint Products Configuration Wizard
SharePoint_AdminContent_<GUID>
Location requirements
Must be located on the same database engine instance with the configuration database.
General size information, and growth factors
Small
If you use Power Pivot for SharePoint and use the default settings that keep usage data collection and data refresh history for 365 days, the Central Administration content database will grow over the span of one year.
Read/write characteristics
Varies
Recommended scaling method
Must scale-up. The database must grow larger because only one Central Administration content database is supported per farm. (Significant growth is unlikely.)
Associated Health rules
None
Supported backup tools
SharePoint Server backup and restore, SQL Server, and System Center Data Protection Manager. Backing up and restoring the Central Administration content databases is special. For more information, see Additional notes.
Default recovery model
Full

Additional notes

Backup and restore. The Central Administration content database is backed up when you perform a SharePoint farm configuration and content backup. When a farm is restored, the Central Administration content database is not restored. The Central Administration content database can be successfully backed up and restored by using SQL Server or other tools if the SharePoint farm is first taken offline.

Content databases

Content databases store all content for a site collection. This includes site documents or files in document libraries, list data, Web Part properties, audit logs, and sandboxed solutions, in addition to user names and rights.

All of the files that are stored for a specific site collection are located in one content database on only one server. A content database can be associated with more than one site collection.

Content databases also store the following:

  • Project Server 2016 data and objects

  • Power Pivot for SharePoint user data

Note

Note that Power Pivot for SharePoint can only be installed on SharePoint Server 2016 when you use SQL Server 2016 CTP 3.1 or higher as the database server. Download SQL Server 2016 CTP 3.1 from Microsoft Download Center.

Power Pivot for SharePoint 2013 can't be installed on SharePoint Foundation 2013, only on SharePoint Server 2013.

Note that to use the business intelligence (BI) tools in SharePoint Server 2013 you must install SQL Server 2012 with Service Pack 1 (SP1) or SQL Server 2014, 64-bit version. For more information, see System requirements for SharePoint Servers 2016 and 2019 and Software requirements for business intelligence in SharePoint Server.

Content database

Category Description
Default database name when installed by using the SharePoint Products Configuration Wizard
WSS_Content
Location requirements
None
General size information and growth factors
We recommend limiting the size of content databases to 200 GB to help ensure system performance. For more information, see Additional notes.
Content database size varies significantly by usage. For more information, see Additional notes.
Read/write characteristics
Varies by usage. For example, collaboration environments are write-intensive and document management environments are read-intensive.
Recommended scaling method
Content databases that support a site collection must scale-up. The database must be able to grow larger as needed. You can create additional site collections that are associated with a Web application and associate the new site collection with a different content database. If a content database is associated with multiple site collections, you can move a site collection to another database. For information about how to size content databases, see Storage and SQL Server capacity planning and configuration (SharePoint Server).
Associated Health rules
None
Supported backup tools
SharePoint Server backup and restore, SQL Server, and System Center Data Protection Manager.
Default recovery model
Full

Additional notes

Recommended content database size limitations

Content database sizes up to 1 terabyte are supported only for large, single-site repositories and archives in which data remains reasonably static, such as reference document management systems and Records Center sites. Larger database sizes are supported for these scenarios because their I/O patterns and typical data structure formats have been designed for, and tested at, larger scales. For more information about large-scale document repositories, see "Estimate Performance and Capacity Requirements for Large Scale Document Repositories", available from Storage and SQL Server capacity planning and configuration (SharePoint Server).

Content database size estimation

Content database size varies significantly with the usage of the site. Growth factors include the number of documents, number of users, use of versioning, use of Recycle Bins, size of quotas, whether the audit trail is configured, and how many items are chosen for auditing.

If Power Pivot for SharePoint is being used, the Excel Online files stored in SharePoint Server 2016 grow larger, which increases the size of the content database. For more information, see PowerPivot for SharePoint (SSAS).

If Power Pivot for SharePoint is being used, the Excel files stored in SharePoint Server 2013 grow larger, which increases the size of the content database. For more information, see Plan a PowerPivot Deployment in a SharePoint Farm.

For detailed recommendations about how to calculate the size of a content database, see Storage and SQL Server capacity planning and configuration (SharePoint Server).

SharePoint Server service application databases

The following service application databases are available in SharePoint Server deployments.

App Management database

The App Management database is used by the App Management Service application. It stores the app licenses and permissions that are downloaded from the SharePoint Store or App Catalog.

App Management database

Category Description

Search service application databases

The Search service application has four databases that support SharePoint Server 2016. The four Search service application databases are shown in the following list. The tables that follow the list display the relevant database information.

  • Search Administration: The Search Administration database hosts the Search service application configuration and access control list (ACL) for the crawl component.

  • Analytics Reporting: The Analytics Reporting database stores the results for usage analysis reports and extracts information from the Link database when needed.

  • Crawl: The Crawl database stores the state of the crawled data and the crawl history.

  • Link: The Link database stores the information that is extracted by the content processing component and the click through information.

Important:

In SharePoint 2013 the backup and restore process for all Search service application databases with SQL Server tools is limited to the following specific scenarios:

  • Backup and Restore of the Search Administration database can be done for configuration migration or upgrade activity.

  • Perform a backup and restore of Search service application databases only when the SharePoint farm is fully stopped. When the SharePoint farm is stopped you can back up the farm to snapshots or make a backup with SQL Server tools to ensure the search indexes are synchronized with the search databases. Note that a restore must include all of this backup set.

  • We do not support restoring search database backups that are not synchronized with the search indexes. This might result in unexpected search experiences and has a high risk of search index corruption. You should perform all database backups within the same time frame to avoid databases that are out of sync with each other.

Search Administration database

Category Description
Default database name when installed by using the SharePoint Products Configuration Wizard
Search_Service_Application_DB_<GUID>
Location requirements
The Administration database should fit into RAM on the server so that the server can handle the end-user query load most efficiently. Because of this requirement, it is usually best not to have the Administration and Crawl databases located on the same server.
General size information and growth factors
Medium. The factors that influence growth include the number of best bets, the number of content sources and crawl rules, the security descriptions for the corpus, and how much traffic.
Read/write characteristics
Equal read/write ratio
Recommended scaling method
Scale-up the database that supports the service application instance. Scale out by creating additional instances of the service application, however, the decision to create a separate service application is likely to be based on business, rather than scale, requirements.
Associated Health rules
None
Supported backup tools
SharePoint Server backup and restore, PowerShell, and SQL Server.
Default recovery model
Simple

Analytics Reporting database

Category Description
Default database name when installed by using the SharePoint Products Configuration Wizard
Search_Service_Application_AnalyticsReportingStoreDB_<GUID>

Associated Health rules
None
Supported backup tools
SharePoint Server backup and restore, PowerShell, and SQL Server.
Default recovery model
Simple

Link database

Category Description
Default database name when installed by using the SharePoint Products Configuration Wizard
Search_Service_Application_LinkStoreDB_<GUID>
Location requirements
We recommend that if you have sites that have heavy traffic, the Link database should use separate spindles from other databases.
General size information and growth factors
Medium to Large. The Link database grows on disk by 1 GB per 1 million documents fed. The click through data grows linearly with query traffic, 1 GB per million queries.
Read/write characteristics
Write heavy during content processing.
Recommended scaling method
Scale out by creating additional Link database per every 60 million documents crawled. Also add additional Link database per 100 million expected queries per year.
Associated Health rules
None
Supported backup tools
SharePoint Server backup and restore, PowerShell, and SQL Server.
Default recovery model
Simple

Secure Store Service database

The Secure Store Service application database stores and maps credentials, such as account names and passwords.

Secure Store database

Category Description
Default database name when installed by using the SharePoint Products Configuration Wizard
Secure_Store_Service_DB_<GUID>
Location requirements
For secure credential storage, we recommend that the Secure Store database be hosted on a separate database instance or database server that has access limited to one administrator. By default, if the database is hosted on the default SharePoint database server and instance, all database administrators will have access to the Secure Store database.
General size information and growth factors
Small. Size and growth are determined by the number of target applications, number of credential fields per target application, and the number of users stored in each target application. If auditing is turned on, the number of read and write operations performed against a given target application also affects size.
Read/write characteristics
Equal read/write ratio
Recommended scaling method
Scale-up the database that supports the service application instance. You can scale out by creating additional instances of the service application, however, the decision to create a separate service application is likely to be based on business, rather than scale, requirements.
Associated Health rules
None
Supported backup tools

Managed Metadata Service service application database

The Managed Metadata service application database stores managed metadata and syndicated content types. Managed metadata consists of terms in a hierarchical structure that can be used for tagging content and building site collections.

Important:

The Managed Metadata Service is the taxonomy service and provides the Term Store Management Tool in the SharePoint Central Administration website. This tool can also be accessed from each site collection. You can navigate there using the Site Settings menu, and clicking Term Store Management.

The Managed Metadata service application database stores the taxonomy, (terms, structure, and metadata). The Managed Metadata Service is also required for content type syndication, even though this is not a feature of the service, most organizations deploy Managed Metadata using content types so the two are often deployed together.

SQL Server system databases

SharePoint Server is built on SQL Server and uses the SQL Server system databases. SQL Server does not let users directly update information in system objects such as system tables, system stored procedures, and catalog views. Instead, 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.

master database

The master database records all the system-level information for a SQL Server instance. This includes logins, configurations, and other databases.

The tempdb database holds temporary objects or intermediate result sets. For example, it holds all temporary tables, temporary stored procedures, and any other temporary storage needs. The tempdb is recreated every time SQL Server starts.

tempdb

Category Description
Default database name
tempdb
Location requirements
Locate on a fast disk, on a separate spindle from other databases. Create as many files as needed to maximize disk bandwidth. Using multiple files reduces tempdb storage contention and yields significantly better scalability. However, do not create too many files because this can decrease performance and increase management overhead. As a general guideline, create one data file for each CPU on the server and adjust the number of files up or down as necessary. Note that a dual-core is two CPUs.
General size information and growth factors
Medium, depending on activities such as how many users are using the system, in addition to the specific processes that are running. For example, online rebuilds of large indexes, or large sorts cause the database to grow quickly.

SQL Server Reporting Services databases

The following SQL Server Reporting Services (SSRS) can be used as part of a SharePoint Server 2016 deployment.

Important:

If you are running Access Services in SharePoint Server 2013, then SQL Server 2012 is required. The requirements for Reporting Services depend on the mode in which you are running, as follows:

  • Local mode requires only SharePoint Server 2013 and the SQL Server Reporting Services Add-in.

  • Connected mode requires SharePoint Server 2013, the SSRS Add-in, and SQL Server 2016, available in Standard or Enterprise Edition.

Report Server Catalog database

The SQL Server Reporting Services Report Server Catalog database stores all report metadata including report definitions, report history and snapshots, and scheduling information. When Report Server Catalog is used, report documents are stored in SharePoint content databases.
