Consequently, it is achievable to affect recovery time for conditions the place the buffer cache is quite substantial or wherever you'll find stringent restrictions on the length of crash/occasion recovery. Scaled-down values of this parameter impose greater overhead during ordinary processing because much more buffers need to be written. Alternatively, the smaller the value of this parameter, the higher the recovery efficiency, since less blocks must be recovered.

The next example assumes a mission-significant database system for which an entire database backup is created each day at midnight, a differential database backup is produced within the hour, Monday by Saturday, and transaction log backups are produced each individual 10 minutes throughout the day.
