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
Not only backup but also DR site recovery.
