You can boot the RPI off of an SSD nowadays, or boot off an SD card with the root file system on an SSD.

I also used to be concerned about persisting data on a RPIs because of the SD card problem.

But this setup is quite comparable to a standard Linux box with no replication. From there you can setup ZFS if you care to, or be satisfied with daily backups to the cloud.

I poked around and found her product page for the Rpi device, and she does couple it with a 120GB SSD and two USB sticks for backup. https://www.open3a.de/page-open3ABox

Also as this is managed solution, I would offer encrypted offsite "cloud" storage.

Any part of the box fails? Send over a new one the next day which will automatically pull all saved data once the login/password is typed on the setup page.

I'd probably lean the other way. I'd build that so that you could say

"Any part of the box fails? Send over a new one then next day then plug one of the USB sticks in and it'll automatically pull the encrypted saved data from itonce the login/password is entered."

If people are choosing a local box instead of her hosted offering, cloud backup might be a deterrent rather than a feature. For the ultra paranoid you could even sell them a spare which they can keep on-hand to swap in and get back invoicing immediately.

Oh, nice! I've never thought about using flash for backups, that's a very nice trade-off of for form factor and cost efficiency.
