Why Hetzner Snapshots Do Not Fully Protect Your Minecraft World

Hetzner Cloud Backups and Snapshots are useful, but they do not include attached Volumes. This guide explains the risk, the operational consequences, and the safer backup pattern for Minecraft.

Turn this into a backup workflow you can rely on

Use the Backup Guide when you want offsite storage, restores, Discord notifications, and a clear setup instead of isolated backup steps.

Open Backup Guide

The short version

Hetzner Cloud Backups and Snapshots copy the server disk. They do not include attached Volumes.

That single detail creates a dangerous false sense of safety for Minecraft operators who moved world data onto a Volume.

If your live world is on a Volume and you rely only on Cloud Backups or Snapshots, your restore plan is incomplete.

Why this matters for Minecraft

Minecraft world data changes constantly:

  • chunk saves
  • player data
  • plugin or mod state
  • region files

Many admins place ./data or the world directory on a separate Volume for storage flexibility. That is operationally reasonable, but it changes what Hetzner infrastructure features can actually recover.

If the world lives on an attached Volume, a server-level Snapshot will not capture it.

What Hetzner documents

Hetzner's documentation makes three important points:

  • Backups and Snapshots are copies of a server's disk
  • Backups are created automatically once per day
  • each server gets seven backup slots

Most importantly, Hetzner states that Backups and Snapshots do not include attached Volumes.

That is the line many Minecraft admins miss.

Typical failure scenario

A very common layout looks like this:

  • OS and Docker on the main server disk
  • Minecraft world data on an attached Volume

After an outage or bad update, the admin restores a Snapshot and expects the world to come back. What actually comes back is only the server disk state. The separate Volume state is not part of that restore point.

What to do instead

Use Hetzner Backups or Snapshots as infrastructure recovery, not as your only Minecraft backup strategy.

For the world itself, add an application-aware backup path such as docker-mc-backup.

That combination gives you:

  • server rebuild options from Hetzner
  • world-level restore points from inside the Minecraft stack

Safer architecture for setupmc.com-style deployments

For a small production setup, the practical model is:

  1. use Hetzner Backups for the server disk
  2. run itzg/mc-backup for the Minecraft data
  3. test restores with a real restore runbook

If your world is on a Volume, this is not optional housekeeping. It is the difference between a full recovery plan and an incomplete one.

FAQ

Are manual Snapshots still useful?

Yes. They are useful before major infrastructure changes, but they are not a complete world-protection strategy when Volumes are involved.

What if I keep everything on the server disk?

Then Hetzner Backups and Snapshots cover more of your Minecraft setup, but an application-aware backup is still better for consistent restore operations.
