You need to change the Recovery model to FULL. If you are using Microsoft SQL Server 7.0/2000.
If you are using MSDE, please issue the following commands:
osql -E -S [Server Name] -Q "ALTER DATABASE [Database Name] SET RECOVERY FULL"
These will enable transaction logging option for your MSDE databases and allow incremental/differential backup to be run with no problems.
