Thank you for your reply, it's nice to know I can finally check TSV and ESV without fear of messing my save file.
As for the second answer, I do not intend to place the backup on another cartrige, I intend to put it back in the same one (just in case my terrible fear of losing my save file happens..), just not at the same save file, as I intend to use that cart to replay Alpha Sapphire over and over.
