I think that the tile says it all; I am looking for a gratis for business use, portable, very basic, schedulable, backup program for Windows.
It will run once per day and backup two small directories totalling 50mB. No further features are needed.

Open control Panel -> Administrative Tools -> Task Scheduler.
You can create any simple repeatable task to fire at any time you'd like, such as 4:00 am when you're otherwise not using the machine.
I've used this before for this very purpose, copy active work to some place every night just in case the next day is one of those "everything I touch turns to crap" days - which happens...
Hope that works for you
backup_YYYYMMDD.zip
and use the copy/move commands to put it where you like. Let me guess: you don't want to keep backups eternally, but only the last N (one more requirement)? For 365 it's easy by naming itbackup-DOY.zip
(DayOfYear), for weekly*DOW*
etc. so you have a "ring buffer" (the oldest file gets overwritten). As for compression: I didn't say so. Simply "store" (1 file per backup, easier to handle).
