I noticed an interesting feature that’s released with SQL Server 2012. In this version now you can set recovery time at database level. In other words now you can set when checkpoint should happen to a database which directly relates to the recovery time of the database. Before stepping into further I would like to explain you what’s recovery time and how does it matter in recovery situation.

Day 14–Trace Flag 3505–Control SQL Server Checkpoint Behavior
What’s is checkpoint? Checkpoint is a process which will write all dirty pages (modified page in buffer cache which is not written to disk) from buffer cache to disk. It helps in recovery time of the database so that when the database start’s up there is no need to do this for all dirty pages, so checkpoint happens in an regular interval. For more information on checkpoint refer the KB article http://msdn.microsoft.com/en-us/library/ms188748.aspx.
