This is the most simple solution and probably a lot safer than the alternatives. Another good option would be to use OpenVPN.

I would say no. The main benefit of having lossless audio is for archival and transcoding, neither of which matter in the context of streaming.

That being said if you are using Bluetooth headphones this will avoid possible double transcoding, and if you want the maximum quality no matter what then yeah consider lossless streaming.

Other than that? Not worth it. I have extremely high end electrostatic headphones and I still use YouTube Music. Modern codecs like Opus, AAC, and Vorbis are all perfectly capable of producing compressed audio that you cannot tell apart from the source.

If a program screws up and crashes while writing data to your drive, it can take out more than just the data it was dealing with. RAID will simply destroy data on both your drives at the same time, making any data recovery impossible.

Someone on lemmy here suggested Restic, a backup solution written in Go.

I back up to an internal 4TB HDD every 30 minutes. My most important files are stored in an encrypted file storage online in the cloud.

Restic is good stuff.

Part of being free and accessible for everyone is allowing defederation.

That’s not how the fediverse works though. Google and Facebook were the two biggest sites online, but even then they still couldn’t “squash” the world wide web, the most successful federated service.

By being the first major social network to adopt activityhub, it means they have an advantage when/if activityhub takes off.
