Server configuration: recovery interval (min) - SQL Server The recovery interval (min) 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 to issue automatic checkpoints on a given database
Adjust TARGET_RECOVERY_TIME to Reduce SQL Server IO Spikes Now let’s reduce the TARGET_RECOVERY_TIME to 15 seconds which will have the side effect of increasing the frequency of checkpoints on the database where we are seeing the IO spikes Here is the TSQL to change this setting
Target Recovery Interval and Indirect Checkpoint If the Target Recovery Time (Seconds) is set to zero (0), it means that the database uses automatic checkpoint By setting a value greater than zero (0), the new, indirect checkpoint will be
0 to 60 : Switching to indirect checkpoints - SQLPerformance. com I quickly decided that I wanted to track checkpoint durations for a few of these more troublesome databases, before and after changing their target recovery interval from 0 (the old way) to 60 seconds (the new way)
How to check recovery status progress of a SQL Server database Object Explorer > YourServerName > Management > SQL Server Logs > most recent Current Opened up a log viewer that shows the recovery process of the database: 'Recovery of database 'MyDatabase' (10) is 55% complete (approximately 1066 seconds remain)'
Common SQL Server Consulting Advice: Setting Target Recovery Interval DECLARE @sql nvarchar(max) = N''; SELECT @sql += N'ALTER DATABASE ' + QUOTENAME(d name) + N' SET TARGET_RECOVERY_TIME = 60 SECONDS;' + NCHAR(13) FROM sys databases AS d WHERE d target_recovery_time_in_seconds <> 60 AND d database_id > 4 AND d state = 0 AND d is_in_standby = 0 AND d is_read_only = 0; SELECT cmd = @sql;
Target Recovery Interval and Indirect Checkpoint - Catalyze SQL If your value of ‘recovery interval (min)’ is set to zero, that means automatic checkpoints are typically occurring every minute Setting Target Recovery Time (Seconds) to 60 at the database level maintains the same checkpoint interval, but uses the indirect checkpoint algorithm
Database Settings Changed Away from Defaults - Brent Ozar Unlimited® SQL Server has flipped the Target Recovery Time default setting around back and forth between 0 and 60 People have seen it at different numbers in the wild, and Microsoft’s SSDT is reported to tweak it too We’re fine with either of those numbers – but if that value is important to you, you may want to dig deeper
How to Optimize SQL Server Recovery Interval in High-Transaction . . . Optimizing the SQL Server Recovery Interval in high-transaction environments requires balancing recovery time, I O load, and compliance needs Adjustments should be guided by workload patterns, infrastructure capabilities, and automated monitoring tools
