I agree that at that price it's not a good idea, but I also think there
might be some room here for negotiation.
Checking Amazon S3 prices, 5 TB would run us $550 per month at the regular
rate. So the price isn't astronomical.
The odd point for me, is that we have multiple VMs based on their advice,
technically we only have 2 machines, if you count clients that way we are
talking 1 TB of space at $100/month, if we need 2 TB then maybe we could
negotiate for say $150-200 a month (1800-2400/yr) which seems much more

We should also realize we don't backup everything this way. The download
server has long operated on make an rsync of it. Many of the old foss4g
websites and uploads contained are archival in nature, not changing. So I
think we should calculate out what's static and what's dynamic.

Basically a full dump of the downloads folder every week seems silly, but a
full dump of various postgres/mysql databases running sites and compressed
on dump seems good, but that won't take the same space it takes on the
running server. So I think estimating disk space based on a full 1:1 of the
complete amount of disks we have is quite an overestimation of our needs.

Just want to make sure we do a good comparison before deciding and factor
things in like "cost" of maintaining the backups.
