It's always worth it though, isn't it? One of these days I will make two backup copies of all my legendaries, shinies and important team members I spent time breeding/training: one for storage on my second game cartridge and the other for PokeBank (since I worry about my save file health due to all the cloning).
Okay, make that 5 then. Forgot I did two for myself then three. Still bit of time for it all, but you're right. It is worth it. I've cloned all my shinies I've hatched/caught and put them in Pokebank to be part of my shiny dex. Plus kind of keep them there so when I train and evolve them, I still have them in level 1 form.
I'm kind of anal like that as well though. It's a copy so I can revive them in original form if I need to. But also as a backup. Should something happen to any of my saves, I have my most precious Pokemon still there for me. I keep extra event Pokemon in an Event folder in Pokebank as well. Recently tossed in my CoroCoro Charizard, later today gotta toss in the Darkrai.
Of course, even though I've never had any save problems in past with Pokemon games, I'm anal at this point I'll lose them. Just wish we could get Gen 1 Pokemon off. I'd kill to have my original Venusaur before it dies. (Last check I did it hadn't yet.)
Edit: Though to be fair, I question the health of the save file more due to WT. Having to save, I know why they do it, but having to save before every time even before i got into cloning made me question the health of the save file. And also why I don't do it as much.
