We backup the databases on the production server. No need to backup the database on the reporting server (the replicated server). Would be rather redundant.

Also, the T-SQL Checkpoint is done to write all the dirty pages to disk. We do that just to "clear things out" of the databases we aren't backing up.

I'd like to do that in my SSIS package. I know that's somewhat vague but this is what we've been doing for quite sometime but I'd like to simplify the process by using SSIS.
