I have been looking into this, and my current idea is tending towards using VMs running DragonflyBSD. VM-1 - local NFS server that runs DBSD and Hammer filesystem with many nice features (auto snapshots, etc.) Will be fast, especially if the VM-1 is on the same physical host-node as my worker VMs. VM-2 is remote, and receives the DBSD filesystems I send it. All snapshots etc. from the original FS are retained. If the connection is interrupted, the Hammer sync code will figure it out and restart from the latest successful transaction.
