This might not be exactly what you're looking for, but in terms of having local backups I like to use Bvckup2 (https://bvckup2.com/). It's perpetual software, data is saved to your chosen destination (I use a separate portable & encrypted SSD to backup all my personal files, but local network servers might work too),…
Is there any tutorials on how to get a custom character, textured, materials edited on it, and ready for presentations? Is SSS shaders and metal shaders covered?
