ZFS: Use mirror vdevs, not RAIDZ

Unless you have tons of data churn or really love burst uploads, you should treat Jottacloud as roughly 15TB of capacity. Here's the speed chart: https://docs.jottacloud.com/en/articles/3271114-reduced-uplo...

So for 24TB you would use two accounts, assuming they're fine with that, and your uploads would run at 5Mbps per thread, with 12 threads in parallel.

That will let you upload 100GB every 4 hours, which should be enough. And the total cost would be 180EUR/year, which is pretty far from $1000.

Thanks for taking the time to explain the details of their offering. I agree that looks well thought out and a much better value than anything else I've seen, especially for the market of personal NAS stuff we're talking about. And a quick search looks like it can be supported by Free (ie secure) backup solutions like duplicity.
