I have some automation that does a weekly archive of everything important to a ZFS-based NAS. Home directories are also stored there over NFS, with hourly/weekly/monthly snapshots.

Once a month or so, I plug in two separate 5TB external HDDs and run a backup script that rsync's everything to each one (2 is 1 and 1 is none). These are stored outside my home.

I should probably get some kind of cloud-based / encrypted backup thing going as well. I don't claim that my current backup system is very good.

https://www.rsync.net/ does ZFS receives, so you can send those encrypted / without unlocking.

That's minimum $60 p/m, a bit steep.

There are a couple of different offers. https://www.rsync.net/signup/order.html?code=710b50 is hn discount. There's https://www.rsync.net/products/git-annex-pricing.html and https://www.rsync.net/products/borg.html

I recommend Backblaze B2 - $5 / TB, and supports s3's api.

Backing up 100+ gigs of data to Backblaze B2 is PAINFULLY slow. I tried to back up a few terabytes and gave up after a few gigabytes because it was so extremely throttled (paid plan) that a backup would have taken weeks or months to complete. (I have gigabit fiber optic service).
