Mail server, but mostly because deliverability in this day and age is a nightmare. If you're some one off running your own mail server in 2023 be prepared to deal with many headaches around IP reputation.
If you've got a copy of the data that's local, why are you opening up ports? Just run the backup job internally.
I'm also not fond of using SBCs as a NAS, by nature their I/O is extremely limited. It will probably work as a backup, but man do I not trust a USB interface at all.
I also recommend not relying on email for notifications - too unreliable. I use the healthchecks.io docker image and have it send me notifications via Pushover when something fails.
People who value their sanity. WiFi is unreliable.
All the servers I've spun up in the past few years have been Debian instead of my usual Ubuntu.
The last straw was kinda when I learned that installing docker via the install menu gives you the snap version instead of the normal one, with no indication that this is the case.
Who in the world is using a USB printer in 2023?
Ethernet bby
Lemmynsfw.com has plenty
As others have said, bitwarden. I've also heard good things about roboform.
I really love that bitwarden is not only open source but has been professionally code reviewed, and can be self hosted if you've got the knowledge to do so.
Of course, if you're self hosting it make sure you have a solid backup strategy for your vault.
I've been testing some alternative SBCs like the OrangePi 5.
Currently mine is a fallback DNS server and reverse proxy for my network, trying to come up with some other uses for it.
They're still low power ARM boxes, but they're much cheaper than the RPi is at the moment.
I really hope you have that backed up
I'm using DuckDNS, it has a plugin for pfSense / OpnSense.
Sounds like a cost of living adjustment to me.
I'd also like to know where these surveys are being run, as the COL varies wildly between states.
