Ok, so you're at 25/mo + 5/mo + 10/mo = $40/mo for self hosted. That's almost exactly "halfway between 12 and 70/mo". Plus, S3/Glacier and a backed up hard drive (even with raid) are nowhere near the same product.
But like I said, my internet bandwidth + quota is not high enough to replace my fileserver with cloud hosting, so I'd still have that expense -- and the $25/month fileserver also acts as a security camera recorder, a media server and a few other things, so it's more than a fileserver.
And yeah, S3 is not a fileserver replacement,AWS's best solution for that would be EFS, but that'd cost me $900/month for my usage.
