More broadly speaking, distributed backup and similar stuff generally needs reliability guarantees that Freenet can't provide. Also, look at their goals - performance is important, privacy is not. Until and unless Freenet shows that it is in fact possible to have really good performance while still having hard privacy, this is not an appropriate use case. One interesting factor is that we should have tools to probe data retrievability without having to bootstrap a new node, and to automatically maintain either your site or somebody else's. This is planned, or at least, there's a bug for it and it's been suggested many times. -------------- next part -------------- A non-text attachment was scrubbed...
