Indeed. Another example would be that of scientific computing. If I've got a job that has been running for a couple of weeks, and will finish in just a couple weeks more, I'd rather not reboot the system. Redundancy gains me nothing (since I'm utilizing all my computing resources already). The code could be trained to checkpoint (and some of my code is so enabled), but that generally has a high cost (in terms of bandwidth and disk use), so you don't want to checkpoint very often, if at all.
