Short answer: on-device snapshots are free, cloud backup needs a subscription
The safest way to back up a Minecraft world is to take a manual snapshot on your device first, then decide whether to go to the cloud:
- On-device manual snapshot (free) — In TopoBlocks, create a local snapshot of the world, recording this version’s hash, size, and source. The data stays on your device and isn’t uploaded; you can use it to review or restore at any time.
- Cloud backup + version history (World Pro, ¥22/mo, 20GB) — If you want off-site storage and the ability to retrieve worlds after switching devices, subscribe to World Pro. It adds cloud storage and version history on top of on-device snapshots.
Two things worth emphasizing: a world is uploaded to the cloud only after you explicitly authorize it — the app never quietly uploads behind your back; and prices are shown in the app, as are the subscription terms. If you just want to understand how backups work in the first place, start with Back up a Minecraft world.
How to use cloud version history
A backup isn’t just “saving a copy” — it’s about being able to retrieve “the version from a specific point in time.” Here’s how TopoBlocks handles it: every backup creates a new version, and cloud version history records each version’s hash, size, and source, so you can go through version by version to see when you changed what and which version to roll back to.
Because every version carries a hash, the same world isn’t silently rewritten — what you see is a traceable chain of versions, not a single file that keeps getting overwritten. To learn how version history and “restore as a new copy” work in detail, see How to use version history and “restore as a new copy”.
One honest note: cloud backup stores the world files themselves — it keeps them off-site and lets you retrieve them by version, but it won’t fix non-file problems like in-game mod conflicts or version incompatibilities. Those need a separate diagnosis/repair workflow.
Restore never overwrites your current world
This is a product red line, worth stating one more time at the end: restore creates a new copy by default and never overwrites your current world. Whether you restore from an on-device snapshot or from cloud version history, your existing world and the original files — along with their hashes — are kept and remain traceable, so a single restore won’t lose your current progress.
If you’d rather not click manually every time, you can set up automatic backups; see How to automatically back up a Minecraft world. Automatic backups that involve the cloud still require your explicit authorization, and restores still create a new copy. If a paid job fails, you’re automatically refunded. Prices are shown in the app.
