eShop compatibility = easy save backups, cloning Pokemon and "multiple" files?

You can just backup your SD card's data to your computer hard drive and make as many copies as you'd like, right?

How so?

You trade all of your Pokemon to your friend's 3DS, then overwrite the SD card with a previous backup. You now have all of your Pokemon back again.

NOPE!

I made a topic about this already..it doesn't work that way. If you overwrite your SD card, the old data on your computer may become unusable. The only way for multiple save files to work is if you download the game multiple times on multiple SD cards.

Sorry, I'm a bit confused because I admit I've never tried this before >_>

When you say becomes unusable, what happens? Does the save become corrupted or something? The only way I could see this is if the 3DS checked timestamps or something like that. Otherwise, you're writing an exact image of what's been on the SD card previously.

Save file is encoded to the SD card ID.

Yes. So let's say for example you downloaded the game on the SD card you're using right now right? Then you wanna transfer data to another SD card using the computer? Yeah, data will work fine on that new card but once you save your game or play through it on the new card, data will become unusable on the old card.
So you would have to download the game multiple times on multiple cards to have multiple save files. Don't worry, once you purchase the game on the eShop, you can download it how ever many times you want. (I'm not sure if there are limits)

I read another website (unfortunately can't be linked here due to piracy discussion) and I think their explanation is clearer now:

What the game does is, every time you save, it writes a Save ID number or timestamp to the 3DS internal memory as well as the SD card.

So let's say you start out with Save #1, which has 100 Pokemon on it.

You back up the data for Save #1 from your SD Card to your computer.

You trade those 100 Pokemon to a friend, now your Save ID is updated to 2. This ID is updated in the 3DS' memory as well as the new SD card save.

You wipe your SD card containing Save #2 and try to restore data for Save #1 from your computer back to the SD Card. Once this SD Card is inserted into the 3DS, the game will complain that there is an ID/timestamp mismatch and will delete your data for being corrupted.

Couldnt you just rename the first file to match the name of the second save after backing them up?
