I'm at OVH as well (in the BHS datacenter, fortunately). I run my entire production system on one beefy machine. The apps and database are replicated to a backup machine hosted with Hetzner (in their Germany datacenter). I also run a tiny VM at OVH which proxies all traffic to Hetzner. I use a failover IP to point at the big rig at OVH. If the main machine fails, I move the failover IP to the VM, which sends all traffic to Hetzner.
If OVH is totally down, and the fail over IP doesn't work, I have a fairly low TTL on the DNS.
I backup the database state to S3 every day.
Since I'm truly paranoid, I have an Intel NUC at my house that also replicates the DB. I like knowing that I have a complete backup of my entire business within arm's reach.
