Didn't need it but out of curiosity I tried to find it in my PC. Couldn't find it. Anyone have any ideas where it would be?

As jtonline said in his reply, it's probably held on the Mazda Naviextras servers. In fact, the backup process is so extremely quick it must just be a flag held against your username allowing a restore - essentially a reinstall - to take place were the files on SD card become corrupted in some way.

It may be of interest that the install files downloaded when running the install process in the Toolbox app are stored on the user's PC - for Windows, it is in the folder C:\Users\{Username}\AppData\Roaming\Mazda\download_cache. These are not removed once the SD card has been successfully updated until I assume the next download takes place. They take up around 6 GB currently. I doubt if these would be used in the restore process.
