Here's how you can control exactly when and what type of database backup you are getting:
1) Create two schedules for your SQL server(s). One with the backup type set to FULL, and the other set to LOG.
2) For the LOG backup schedule, configure that to be a repeating schedule throughout the day. In your case, every 15 minutes.
3) For the FULL backup schedule, configure that to happen just once a day. In your case this would happen once each night after your LOG backups end.
SMART mode is an easy way of automatically handling SQL backup jobs, but should probably only be used for customers backing up SQL once each day. For more information on how each backup type works, check out our TechLib article:
