Configure the recovery interval Server Configuration Option

Article
06/13/2017

This topic describes how to configure the recovery interval server configuration option in SQL Server 2014 by using SQL Server Management Studio or Transact-SQL. The recovery interval option defines an upper limit on the time recovering a database should take. The SQL Server Database Engine uses the value specified for this option to determine approximately how often automatic checkpoints to issue automatic checkpoints on a given database.

The default recovery-interval value is 0, which allows the Database Engine to automatically configure the recovery interval. Typically, the default recovery interval results in automatic checkpoints occurring approximately once a minute for active databases and a recovery time of less than one minute. Higher values indicate the approximate maximum recovery time, in minutes. For example, setting the recovery interval to 3 indicates a maximum recovery time of approximately three minutes.

Before You Begin

Limitations and Restrictions

The recovery interval affects only databases that use the default target recovery time (0). To override the server recovery interval on a database, configure a non-default target recovery time on the database. For more information, see Change the Target Recovery Time of a Database (SQL Server).

Recommendations

This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
Typically, we recommend that you keep the recovery interval at 0, unless you experience performance problems. If you decide to increase the recovery-interval setting, we recommend increasing it gradually by small increments and evaluating the effect of each incremental increase on recovery performance.
If you use sp_configure to change the value of the recovery interval option to more than 60 (minutes), specify RECONFIGURE WITH OVERRIDE. WITH OVERRIDE disables configuration value checking (for values that are not valid or are nonrecommended values).

Security

Permissions

Execute permissions on sp_configure with no parameters or with only the first parameter are granted to all users by default. To execute sp_configure with both parameters to change a configuration option or to run the RECONFIGURE statement, a user must be granted the ALTER SETTINGS server-level permission. The ALTER SETTINGS permission is implicitly held by the sysadmin and serveradmin fixed server roles.

Using SQL Server Management Studio

To set the recovery interval

In Object Explorer, right-click server instance and select Properties.
Click the Database settings node.
Under Recovery, in the Recovery interval (minutes) box, type or select a value from 0 through 32767 to set the maximum amount of time, in minutes, that SQL Server should spend recovering each database at startup. The default is 0, indicating automatic configuration by SQL Server. In practice, this means a recovery time of less than one minute and a checkpoint approximately every one minute for active databases.

Using Transact-SQL

To set the recovery interval

Connect to the Database Engine.
From the Standard bar, click New Query.
Copy and paste the following example into the query window and click Execute. This example shows how to use sp_configure to set the value of the recovery interval option to 3 minutes.

USE AdventureWorks2012 ;  
GO  
EXEC sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE ;  
GO  
EXEC sp_configure 'recovery interval', 3 ;  
GO  
RECONFIGURE;  
GO
