According to a report from Ars Tehnica, there is actually no way to backup your save data on the Nintendo Switch which can be pretty dangerous in the event of you losing your save files.
In a post-launch update to our initial Nintendo Switch review, we noted that there is no way to externally back up game save data stored on the system. A recent horror story from a fellow writer who lost dozens of hours of game progress thanks to a broken system highlights just how troublesome this missing feature can be.
Over at GamesRadar, Anthony John Agnello recounts his experience with Nintendo support after his Switch turned into a useless brick for no discernible reason last week (full disclosure: I know Agnello personally and have served with him on some convention panels). After sending his (under warranty) system to Nintendo for repair, Agnello received a fixed system and the following distressing message from the company two days later:
We have inspected the Nintendo Switch system that was sent to us for repair and found that the issue has made some of the information on this system unreadable. As a result, the save data, settings, and links with any Nintendo Accounts on your system were unable to be preserved.
Agnello says he lost 55 hours of progress on The Legend of Zelda: Breath of the Wild, as well as more progress on a few other downloadable games. While he was able to redownload the games that were deleted, he’d have to start from scratch on each one (if only all that progress was easily, instantly unlockable in some way…)
Apparently, the Wii U had the same issue with backing up saved files as the Nintendo switch does now. One would think they had learned from their past mistakes.
The Nintendo switch was released March 3, 2017 and has sold more than 500,000 units already.
