Perché ho bisogno di uno storage a blocchi?

Yes, I understand. The costs isn’t a major concern here, but more of server management. The reason why I’m hesitating Amazon S3 because based on my experience, it’s usually for big websites with user-generated content only. And the caveat of going for it is its rigidity. You… are stuck with the Amazon S3 forever. You can’t change or undo, because the URLs can’t be undone unless done manually.

And I’m very confused with this Discourse forum software. Since there’s no cPanel, and there’s no documentation for me to review, I’m very concerned that my complete ignorance of how this entire things work may spell trouble in the future when I move servers. Like I really need to know why block storage is needed, if I don’t, where are the files stored? And how can I access the code files? And is it convenient to move Discourse between servers, or restore from backup? (I don’t even know how to use SSH to manage files, I’m worried I can’t restore from backup quickly enough if problems arise)
