OBSD Amsterdam is pretty cool. I am currently running an instance on it. One feature that could also be considered a bug is that the VPSes run on the native OpenBSD virtualization scheme. My instance has suffered a few crashes over the years. It's been solid more recently. I suspect that OBSD Amsterdam and users have contributed to improvements to the native virtualization.

So you control your instance by sshing into a BSD account on the server. You configure your reverse DNS the same way. It's OpenBSD all the way down. So, as mentioned, pretty cool. Possibly not for the OBSD user who prefers some sort of web based configuration for their VPS.

It comes with access to a server you can copy your backups to. You of course do that from your instance using ssh.

You could also manually partition.

As an OpenBSD noob I prefer not to until I get a good feel for how much will end up in them across a few sysupgrades.

If you run it as a server mostly, I think the home partition at least can be shrunk to like 2GB or something.
