I run Truenas scale on home server and on the off-site backup at a friend’s house. ZFS Snapshots get synced to backup server nightly. The snapshot system is nice because it only needs to send what has changed since the last synced snapshot.

Now that I have it setup it is mostly no effort on my part. But the initial ramp up to understand Truenas and ZFS was a second job for a few weeks. HexOS may be good choice if you want the power of Truenas but the handholding of setup wizards and such. But HexOS is currently $200 and Truenas is free. Pay in time or dollars.

Linus has literally talked about that multiple times. He learns just enough to cover what is needed for the video, does the video, then forgets most of.

They are more entertainment and light education. They are trying to target a very wide audience, so they can’t really do deep on things. For actually learning I like LearnLinuxTV and LawrenceSystems.
