To continue the series on disaster recovery scenarios in SQL Server 2005, let us look at another means to increase the availability of your highly critical databases. Isolating critical objects gives you the advantage of increasing your database availability. You should create a separate filegroup for your critical database objects. In fact, you should be creating your database objects in a different filegroup other than the default primary filegroup. Most of the time, we think of filegroups as a means to improve performance or manage database files. However, we tend to forget the fact that filegroups can be used as a means to improve database availability and should be considered as part of our disaster recovery plan.
