Questions about back ups on BBM

For what it’s worth (good song, BTW):
I insert the SD card into my computer,
I launch BBM, which detects the SD, asks me if I wish to create a backup.
I always select “no.”
I make sure to save the project TO the SD card.

Whenever I have selected “yes,” BBM uses my last backup as the Project folder. I don’t believe it syncs changes to the SD, but I could be mistaken.
If I want to back up my SD card, I do so manually, independent of BBM.

Should I have to do it this way, or will BBM sync changes back on to the SD card?
