As of November 20, 2012 @ 23:00 GMT -5, the database backups available on the Sync site are now SQL Server 2008R2. In order to use the database with a SQL Server 2008 instance, the database will need to be restored to a 2008R2 instance and then the data exported to a 2008 instance. We are working on a feature that will be available within the Sync site to automate the process of obtaining a backup in the older 2008 format.
