ModelDB Recovery Model best practices report by SPDocKit determines whether the model database is set up correctly.
This check determines whether the model database is set up correctly.
SharePoint Server uses SQL Server to store configuration and user data. Therefore it is extremely important that SQL Server be as optimized as possible. The model database can be set up in such a manner to reduce administration overhead significantly.
The model database is used as the template for all databases created on an instance of SQL Server. The entire contents of the model database, including database options, are copied to the new database. Changing the settings on the model database will affect all databases created afterwards.
There are three database recovery models in SQL Server:
Simple – No log backups. The following operations are not supported, as they require transaction log backups: Log shipping, AlwaysOn or Database mirroring, Media recovery without data loss, Point-in-time restores.
Full – Requires log backups. No work is lost because of a lost or damaged data file. Can recover to an arbitrary point in time (for example, prior to application or user error).
Bulk logged – Requires log backups. This is an adjunct of the full recovery model that permits high-performance bulk copy operations. If the log is damaged or bulk-logged operations have occurred since the most recent log backup, changes since that last backup must be redone. Can recover to the end of any backup. Point-in-time recovery is not supported.
Because the model is small and rarely changes, backing up the log is unnecessary. However, all new databases will use settings from the model database. Therefore, it is advisable to set the recovery model on the model database to Full to reduce the administration overhead.
Set recovery model on the model database to Full. To do so, start SQL Server Management Studio and connect to the SQL server instance which hosts your content databases. In the Object Explorer tree, navigate to Databases > System Databases, select the model database, right-click on it and click Properties. In the Database Properties window, select Options page. Click the Recovery model drop down box and select Full. Click OK to exit and save the changes.
