Client: Help, emergency. I have 24 hours to move my workload to another server. What do we do?
Me, five minutes later: "Done. Your workload is now running on the new server."
Client: "How did you move over 200GB with just a minute of downtime, from one provider to another and in a different country?"
Me: "Thanks to FreeBSD, ZFS, and a little bit of proactive planning."

I have a task that replicates all the VMs from one server to another every 15 minutes using zfs-send/zfs-receive. This VM connects to a VPN with two reverse proxies.
Meaning, when I move this VM, we don’t need to change any IPs since it’s not directly exposed.
I powered it off, cloned the differences in seconds, and restarted it.

Client in disbelief.
Me, relaxed and happy.

Thank you, FreeBSD, thank you, ZFS!
