What a server world snapshot is and how to use it

A server world snapshot is a traceable copy of your live world taken at a point in time, used as a rollback point before a deploy or update—so if an update breaks the world, you can return to the state captured in that snapshot. With TopoBlocks’s full management feature you can create a remote snapshot of a live world:

  1. Authorize full management to connect—a snapshot is a write operation, so you have to explicitly authorize full management for the target server. The free “monitor only” mode only shows online status, version, player count, and latency; it has no write access and can’t take a snapshot.
  2. Create a remote snapshot—save a copy of the live world, recording the hash, size, and source so it’s traceable.
  3. Verify restorability—full management includes a “snapshot is restorable” check that confirms the snapshot can actually be restored, rather than saving a file that turns out to be unrecoverable.

Restoring never overwrites your existing world

A lot of people worry whether “restoring will wipe out my current world.” It won’t. Restore creates a new copy by default, and your current live world and the original files, along with their hashes, are all preserved and traceable—never overwrite the source files, and generate a new traceable version every time is a product red line that both snapshot and restore follow.

The most common use of a snapshot is alongside a safe deploy: take a snapshot and verify it’s restorable before replacing the world, and after going live, if the health check fails, it automatically rolls back to the pre-deploy snapshot. To learn how to make this process more reliable, see Updating a server world safely and the in-depth tutorial Safe server world deploys. For how to roll back when something goes wrong, see How to roll back a broken server world.

A few honest notes

  • A snapshot is not all-purpose insurance. It only covers the moments you’ve actually taken snapshots; earlier or later changes you never snapshotted aren’t included—so we recommend taking one before every important update.
  • Full management is a paid feature that only runs after your explicit authorization; prices are shown in-app, and failed jobs are refunded automatically. The free monitor-only mode doesn’t read the world directory and needs no credentials.
  • Beyond servers, you can also take manual snapshots of local worlds to protect your saves (with a subscription you also get cloud backup + version history). To add a layer of safety to the world saves on your phone or computer, see How to back up a Minecraft world.
