Not long ago I came across a graph plotting acceptable system downtime and acceptable data loss in an easy-to-understand format in the context of disaster recovery. The idea of the presentation was that acceptable maximum downtime limits and maximum data loss limits should be agreed with the business/customer in the SLA, and these thresholds guide the DBA's disaster recovery strategy.

I've seen this graph/concept before in a couple of places, and it has a specific name, too, but it's eluding me. Does anyone know what I'm talking about and can post a link or more details (or did I just dream the whole thing up?)

Thanks!

Do you mean the Recovery Time Objective and Recovery Point Objective? RTO being how long it takes to get back online and RPO being how much data you can afford to lose.
