I've been reading about the new Management Data Warehouse (MDW) feature in SQL 2008. It looks good on paper. Instant baselines, trend analysis capabilities and historical performance analysis are all potentially a click away. There are canned reports with drill-down capability out-of-the-box.
By default you get 2 years of file size data (data and logs) and 2 weeks of query and system info before the automatic purge routines kick in.
My question is to those who have actually implemented this as a solution: How do I archive the reports?
Based on what I've read the MDW grows by 1 GB every 3-4 days or so. But for true performance analysis you would want to be able to look back over long periods.
I'm sure someone will have a quick, easy answer but I haven't stumbled across it yet.
As an aside... if you have set it up - how is it working for you?
