Operation 4. Log Files are Truncated
Once the log files are stored to the backup set, they are no longer needed on disk. During full and incremental
backup operations, ESE truncates the log files on disk once transaction log back up is completed. The lower of
either the checkpoint log generation or the log generation listed in the database header for the current full
backup determines which log files ESE truncates.
Operation 5. Backup Operation Complete
After the log files are truncated, the backup operation is complete and the backup application closes the
backup set. ESE returns to normal database-engine operations and permits the checkpoint to advance.
