Here's how I do it:

Regularily backup pages 0x800 [RAM] (to 0x1FE) and 0x804 [MMU] (to 0x1FF) to flash.

Then, semi-regularly backup those flash pages to PC via HP-IL using the CLILUP module.

See my full backup/restore system here: https://github.com/isene/hp-41_CL

And of course the HP-IL update system here: https://github.com/isene/hp-41cl_update

Thanks @Geir for this link, I'll enter the program later today and will report back. Appreciate you sharing it!

Waiting for @Monte to tell us about the V5 board behavior regarding sector 1F8 as per @Angel's comment. I was naively assuming upward compatibility (what works on V3 works on V5) which shows my ignorance when it comes to hardware. He probably also put it in the manual and I just cant find it / understand it...
