Doing something very similar, hosting a lot of things on a Raspberry Pi 4 with 400 GB SD card.

Not as easy though, I still need to figure backup strategy and everything. My goal is to eventually remove photos, and almost everything hosted entirely really.

What kind of SD card are you using? How many writes/transfer speed? The fact that the card can die on you and lose 400 GB of data gives me nightmares.

I got a Rock Pi recently and it supports M.2 slot and eMMC that goes up to 64 GB, this makes me less nervous.

I have a simple script that tars and gpg encrypts specific directories nightly. It’ll also reap backups in a sane way (only keep one per week for the last month, one per month for the last year, etc). And it’ll stop/start services/containers while backing up as needed. Then I distribute the backups to various devices using Syncthing.

I’ve been thinking about also having an off-site backup (for a house fire, electrical storm when everything is plugged in, etc), but that might be slightly paranoid.
