When you back up your SaaS apps (because you know you are supposed to), should you back them up to a SaaS service or on on-premises backup system? After defining what SaaS is and isn't, Prasanna and Curtis discuss this important question. First they look at how sizing a SaaS system for backup is different than when you do it in a datacenter, and how that creates challenges for backup design. Does it make sense to use on-premises backup to backup a cloud resource like SaaS?
