Vlad Drumea doesn’t need no steenkin’ transaction log backups:
This brief post contains a script that can help switch a whole SQL Server instance, model and all user databases, to SIMPLE recovery.
The script is useful in case of dev/test/QA/UAT instances that have been left by accident to use the default FULL recovery model, yet do not have or need transaction log backups.
Read on for the script. It also shrinks the transaction log file after the switch-over.
