I accidentally deleted one of my StrataFrame projects that had all my BO mappings and stuff... so now I have to re-created them. Is there any way to back that information up and then restore it?

That is why we use SQL Server.  We backup our databases nightly for just that very reason.  There are a number of ways to do this.  You can use a backup utility like Veritas.  Or you may use the standard backup features that come with SQL Server Management Studio.  It allows you to backup to a file on disk and restore the same way.  So when this happens, it is just a few minute problem.  Sorry for your trouble, I know what it is like to have to re-create a project
