Circumstances that promote SQL Server backups to level full

Transaction log backups are promoted to full backups in certain situations.

By default, transaction log backups are promoted to level full in the following scenarios:

When there is not an existing level full backup.
When a log gap is detected.
When the recovery model is changed.
When the backup includes simple model databases, either the simple model databases are promoted to a full backup or the simple model databases are skipped, depending on the backup settings.

Options to tune the behavior of automatic promotion are available while configuring a backup. The ddbmsqlsv -a "BACKUP_PROMOTION" command flag and the Microsoft app agent for Application Direct SSMS plugin Backup Promotion option both control backup promotion.
