You should have all your data separately stored, it shouldn’t be locked inside containers, and using a VM hosted on a device to serve the data is a little convoluted

I personally don’t like TrueNAS - I’m not a hater, it just doesn’t float my boat (but I suspect someone will rage-downvote me 😉)

So, as an alternative approach, have a look at OpenMediaVault

It’s basically a Debian based NAS designed for DIY systems, which serves the local drives but it also has docker on, so feels like it might be a better fit for you.

Definitely suspect.

You should be able to let memtest run for days with no problems, so a reboot would either be a faulty stick or possibly a faulty motherboard slot.

Swap the RAM between slots to isolate the root cause

That’s an interesting point…

I’d like to share some (holiday) photos with my friends & family, so I can put those onto Pixelfed / Friendica / etc… I don’t necesarily want to share all the photos…

And that’s using the cloud.

Job Done. The self-hosting + federated cloud future is here!

Rejoice.
