Interesting point. I think my idea of pushing to a network share and turning the base station into a NAS are two separate and valid ideas. The push is important because it means any existing storage can be used and it does not depend on proximity to the base station. It also doesn’t demand long term storage on the base station. From a development point of view, if they already have the feature to back up to base station, this same feature can be extended to support any network share, like many network printers have.
As for turning the base station into a NAS, that would mean the introduction of a NAS server, security and such. It’s not impossible, to be sure, but it would also have to be a self-powered USB drive. I don’t think the little 12V adapter the base station comes with could power a drive too. I’m just thinking out loud here. On the surface, a good idea but I don’t know if they have enough space in their firmware storage for this. That’s not me being negative, it’s me saying I truly don’t know.
