So I've been burned by Nintendo's antiquated online bullshit systems and had my Pokebank cleared because I didn't get a new 3DS soon enough after I lost my old one. Now I want to use Powersaves to backup.

I've read some shit that says they can brick a game. Are there any precautions I can take? Any tips on how to reduce chance of corruption, etc? I don't intend to use it to cheat, just to backup my saves.
