As far as I’m aware, Calibre-Web serves are web front-end for calibre. I think you might have to install plugins manually on the desktop version, but it should be active when importing a book over the Calibre-web, especially DeDRM.

I get that. But I think the quote refers to corporate infrastructure. In the case of a mail server, you would have automated backup servers that kick-in and you would simply pull the rack of the failed mail server.

Replacing drives based on SMART messages (pets) means you can do the replacement on your time and make sure you can do resilvering or whatever on your schedule. I think that is less burdensome than having a drive fail when you’re quite busy and being stressed about having the system is running in a degraded state until you have time to replace the drive.

I mean if it’s homelab, it’s ok to be pets. Not everything has to be commoditized for the whims of industry.
