The archive server is io-bound[1], and use network bandwidth to
snapshots repositories and serve files through http.
When the build server is cpu-bound with few network traffic and may
suffer of the archive disk usage.

A year of snapshots is about 460GiB, so we can host 2 years of snapshot
on a 1TB server.

So, my preference would go to take one separate server with unlimited
traffic and dedicated disks. OVH and Online.net lease these kind of
servers (don't find such at Hetzner).
If we go trough this option, I suggest this one:
* Online: Xeon E3 1220v2, 16GB RAM, 2x1TB, 300Mbps, 29€ HT [2]

but cheaper alternatives may also fit (with no RAID).
* OVH: i5-750 2.6GHz, 16GB RAM, 1x2 To HDD, 100 Mbps, 14,99 € HT [3]
* Online: Intel C2750, 8GB RAM, 1x1To HDD, 200Mbps, 15.99€ HT [4]

Upgrading celestia is also a suitable solution.
