Advanced - Reconstruction
Solstory deliberately verifies data not data location. This means you're not limited to immutable storage locations to prove data hasn't been tampered with. It also means that data locations can change, and Solstory will succeed in verifying that the data is the same. We call moving all the data from one location to another "reconstruction" and hopefully you'll never have to do it. But, should your storage blockchain/S3 bucket/webserver etc go down, it's possible to use a backup to reupload the missing data somewhere else, then append a new item to your Solstory that points to this new location.
A more detailed guide on how to do so will be written up later (presumably when someone needs it). For now, poke us on discord if you ever end up in this situation.
