I like what u/mosiacmango said.
Also, as someone new to self hosting, Linux, containers, networking and assembling computers, Unraid has made the steep learning curve easier to climb.
From my perspective, staring at Unraid’s Black Friday pricing, it was a no brainer when the alternatives seem to be truenas and maybe Synology. Truenas would’ve had a steeper learning curve, and Synology provides a cookie cutter experience and learning little.
Nice, I’ve been doing something similar, using the obsidian-git plug-in for Obsidian and the Working Copy app on iOS.
Obsidian is my front-end, and it saves the notes in markdown files in a git-synced folder on my computer.
The plug-in pushes and pulls automatically, and Working Copy does the same thing on iOS, just before opening the Obsidian app on iOS.
