It does not seem like you heard the arguments presented in the article. It isn't about being offended by any left or right wing politics, but because women engineers and scientists were uncomfortable about it for a variety of reasons. In a field which struggles to attract and keep female talent, this is a pretty big thing. The model herself spoke out and asked to be "retired from tech".

Is weird that I like and use both Fedora and Debian?

I do the same. Fedora on my laptop because I want a balance of stability and having the newest features. Servers run Debian, because I don't have time to fix and update things.

What are the most paranoid network/OS security measures you've implemented in your homelab?

Logcheck. It took ages to make sure innocent logs are ignored, but now I get an email as soon as anything non-routine happens on my servers. I get emails with logs from every update, every time I log in, etc. This has given me the most confidence that nothing unexpected is happening on my servers. Of course, one needs to make sure that the firewall is configured well, and that you use ssh keys etc., but logcheck is how I know I'm doing enough.

How often do you back up?

How do you upload a snapshot?

Basically, as you said. Mount the data somewhere and back up its contents.

I back up snapshots rather than current data, because I don't want to stop the running containers that read and write from that data. I'd rather avoid the situation where the container is writing data while it's being backed up. The back up happens shortly after the daily snapshot is made so the difference between current and snapshot data is small.

As others have said, with an incremental filesystem level mechanism, the backup process won't be too taxing for the CPU. I have ZFS set up which makes this easy and I make hourly snapshots using sanoid which also get sent to another mirrored pair of connected drives using syncoid. Then, once a day, I upload encrypted daily snapshots to a bucket in the cloud using restic. Sounds complicated, but actually sanoid/syncoid and restic do all the heavy lifting. All I did is automate their schedules using systemd timers and some scripts to backup the right directories.
