I have a 45W 9TB fileserver at home (5x3TB disks, RAID-6), which costs me around $5/month in electricity. Plus another $10 for the Crashplan backup.

I'm using around 3TB of space on it currently, which would cost around $70/month in S3 or $12/month in Glacier (in reality I'd use a combination of S3/Glacier so my costs would be somewhere between $12 and $70/month)

Granted, the hardware costs me around $25/month amortized over 3 years but my internet speed isn't fast enough (or unlimited enough) to let cloud storage be a viable replacement of a local fileserver.

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.
