Native ZFS VDEV for Object Storage (OpenZFS Summit)

Yes, this is a core use case ZFS fits nicely. See slide 31 "Multi-Cloud Data Orchestration" in the talk.

Not only backup but also DR site recovery.

  The workflow:

  1. Server A (production): zpool on local NVMe/SSD/HD
  2. Server B (same data center): another zpool backed by objbacker.io → remote object storage (Wasabi, S3, GCS)
  3. zfs send from A to B - data lands in object storage

  Key advantage: no continuously running cloud VM. You're just paying for object storage (cheap) not compute (expensive). Server B is in your own data center - it can be a VM too.

For DR, when you need the data in cloud:

  - Spin up a MayaNAS VM only when needed
  - Import the objbacker-backed pool - data is already there
  - Use it, then shut down the VM

Could you do this with two separate zpools on the same server?

    zfs send -R localpool@[snapshot] | zfs recv -F objbackerpool

Is there a particular reason why you'd want the objbacker pool to be a separate server?
