DIY Cloud backup 2022 update

Update to the DIY Cloud backup project
2022 update!

In 2017 I built a DIY cloud backup solution (which you can find documented here). This has been running every since but somewhere end of 2021 I decided the used hardware could use a little update.

I’ve been trying to do a video series of basically a re-imagining of the project but I’m having a hard time following it through!

With this post video part 4 (and 5) are going to be released and we are finally heading towards the end of the project!

Lots of External HDD on a single Power Supply

Sometimes you accumulate a lot of equipment in one spot that all runs on 12v. This can for instance be a rack with multiple switches and routers or, as in my case, 15 External Hard Drives, a USB HUB and some fans that all need 12v. To cut down on the clutter, let’s take out the 18 Adapters to run this and replace them with a single power supply.

The absolute best way to get per room temperature sensing into Home Assistant in my opinion!

Innodisk 3TG6-P 2TB SSD Review

I was in need for some 2.5″ storage for an upcoming project and while looking around I wondered if 2.5″ SSDs has approached the price of physical disks. And while close, even QLC SSDs where still much more expensive. But on ebay I was able to find new 2TB SSDs for around 150$, still more expensive then spinning disk but interesting enough to try it out anyway, let’s see how well they perform!

Seagate IronWolf 10TB Firmware Fix (CRC errors with ZFS)

I’ve been using Seagate IronWolf disks for a few years now and currently have about 20 in service, most of those are the 10TB (and 12TB) Non-Pro (ST10000VN0004) variety. Most of my experience with them has been great so when the new server build came along I bought a few more to run as my main ZFS pool. Sadly, things didn’t go exactly as planned, but I think I was also able to fix it, so let’s see what happened!
