I encrypt the data before shipping it off to CrashPlan mostly because it's the most flexible. I have a small amount of "sensitive" data related to my research work. It's not really anything that is actually worth protecting IMO, but I'm obligated to meet certain requirements when storing it. Encrypting it before uploading lets me have more fine-grained control over how it's encrypted. I also like to use different keys for different machines. I do actually trust CrashPlan, but I like doing it this way. The NAS isn't exposed to the internet, so that's not the issue. Restoring from CrashPlan is basically as you describe. Assuming my home NAS isn't destroyed, I've just restored from the appropriate Attic repo for the machine off the NAS. If the NAS was destroyed too, well I'd have to restore from CrashPlan. My backups are targeted though, so a full restore is only at most like a TB of data (basically, my documents, configuration files and music collection).
