I almost certainly don't save any money considering electricity cost. I have a dell r630 for compute and an r730xd that I use as a NAS. Then I have one switch for the rack and a POE switch for the house. Probably 3-5amps total?

If I started over, I would probably choose more efficient gear.

That said, I don't mind paying for the electricity too much. I enjoy the warm fuzzies of knowing my data lives under my roof.

A raspberry pi draws 2+ amps. Your dual Xeon server is drawing a lot more power. That said, typically you’d want to measure in watts because amps is relative. Eg a RPI is 2A at 5V while a computer is probably 5A at 120V - an order of magnitude more total energy consumed.

do you backup offsite? if not, in the event of a fire, your data will live under your "poof!"

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).
