Smart Transaction Log Backups

Tracy Boggiano has started a new series on smart transaction log backups.  Part one involves taking smarter transaction log backups in SQL Server 2017:

SQL Server 2017 introduced two fields to help with taking smart backups.  One was for taking smarter log backups, for this have DMV sys.dm_db_log_stats that have two fields log_backup_time and log_since_last_backup_mb.  With the combination of these two fields, we can put some logic in the jobs that I use for Ola’s scripts that use my config tables from my Github repository.  To support this change we will be added three new fields to the DatabaseBackupConfig table:

  • SmartBackup

  • LogBackupTimeThresholdMin

  • LogBackupSizeThresholdMB

Click through for scripts.
