In one line: a snapshot is a “version record,” a backup is a “copy”

The two terms often get mixed up, but they emphasize different things:

  • A snapshot is a version record of your world at a single moment, carrying its hash, size, source, and more. Its core purpose is rollback — letting you return precisely to “that moment,” and compare and pick between multiple points in time.
  • A backup is a saved copy of your world, kept either locally or in the cloud. Its core purpose is safekeeping — so that if a file is lost or your device has a problem, you still have a copy to get back.

Another way to put it: snapshots are like a series of “time photos” of your world, making it easy to choose which one and which moment to return to; a backup is filing away a separate copy of the whole album. To learn systematically how to make a reliable archive of your world, see Back up a Minecraft world.

The shared bottom line: neither overwrites your current world

Whether it’s a snapshot or a backup, TopoBlocks has one rule it never breaks: restoring creates a new copy by default and never overwrites your current world, and every version it generates keeps a traceable hash.

This means:

  • When you roll back to a snapshot, you get a new copy — your original world is still there;
  • The same is true when you restore from a backup, so there’s no risk of “one-tap restore wiping out your current progress”;
  • Even if you pick the wrong point in time, you simply end up with one extra copy, with zero loss.

To understand the exact steps and caveats of rolling back, see Restore a world from version history.

How to use it in TopoBlocks: the free part and the paid part

Let’s be honest about the boundaries, so you don’t pay for something you can’t use:

  • On-device manual snapshots — free. Take a snapshot of your current world and record its version info; it’s done on your device by default and is not uploaded.
  • Exporting a .mcworld backup — free. Export the world to a single file kept locally or in cloud storage, which is a standalone offline backup.
  • Cloud backups + version history — require a World Pro subscription (¥22/month, 20GB). If you want automatic cloud backups and a longer version history, consider subscribing. Exact limits and pricing are shown in the app.

If you manage a server world, snapshots work a little differently — they get embedded into a safe deployment flow of “snapshot → verify → atomic switch → health check → automatic rollback on failure.” This is part of a full management capability that requires your explicit authorization.
