you just have to

:3:Filename Enter
then do Archive and it Saves everything to the SD Card

if you need to restore then

:3:Filename Enter
then do restore and the 50g is restored

3 is for the SD card
2 is for the Flash memory

I'm lazy I just want to push a button

ARCHIVE does that, sortof. You should save your flags in some variable in HOME. Same thing with your keys. You can turn the stack into a LIST as shown in the doc, something like

DEPTH ->LIST and save it in a variable. Put this all in a program and you have a backup for all you want, except that you have to either delete the previous version or use generated names.

In HP 48 Insights Vol 1. there is a backup program shown. Can you get a copy?

Yes, STARTUP. See User Guide Appendix D-9.

thanks for the tips, I can't get/find that 48 Insights, I now remember something about the STARTUP I'll have to research it some and do more coding

I started to write my own code and it does work good but occasionally gives "object in use" error when it's saving to the SD card.
The built in archive command is good but misses some stuff (like the stack). I'll keep coding my little program but thought there might be something written mostly in RPL that everyone is using.

"Object In Use" can be a bit tricky to debug, because there's a wide variety of causes. One in particular that I believe is consistent is if you try to store something in a port (or create an ARCHIVE) when there's already an object with the same name in that location. I'm pretty sure you'll have to PURGE the pre-existing object before the 50g will allow that. There's other causes, too. Try googling the comp.sys.hp48 group for "object in use" and you'll find quite a few references. You'll also find a wealth of information there pertaining to ARCHIVE, RESTORE, issues pertaining to key assignments, alarms, etc.

Another set of commands you may want to investigate is PUSH and POP. Those might be useful for what you are doing.

PUSH and POP might work for the flag changes in my program but not so much for storing flags, for that i'm RCLF then storing it in a directory just before archiving. next I need to store some STARTUP program to restore the flags and the stack after the RESTORE boots the calculator?

I kind of have it figured out, just need to try some code and add some error traps.
Thanks for all your hints and tips.
