i never know what’s expected on those type of captcha. if the handle bars of a bike go into an adjacent box and are 99% covered by a hand does that count? what do you do when you have a blurry image full of jpg artifacts and are asked to identify if it contains a fire hydrant. I’m pretty sure it usually classifies me as a bot for being too exact since I’m asked follow ups for a few minutes until i give up and just close the tab out of annoyance.

no one understands how these models work, they just throw shit at it and hope it sticks

caches are never really a concern to me they will regen after the fact, from your description i would worry more about db, this is dependent though in what you’re using and what you are storing. if the concern is having the same system intact then my primary concern would be backing up any config file you have. in cases of failure you mainly want to protect against data loss, if it takes time to regenerate cache/db that’s time well spent for simplicity of actively maintaining your system
