# Uninstalling (/operations/uninstalling)

  Uninstalling permanently deletes every service, database and volume on the instance. Download
  anything you need first, and make sure your database backups are somewhere else.

## Uninstall [#uninstall]

On the server, run:

```bash
sudo unbind uninstall
```

It asks you to confirm. Then it removes the storage system and its data, removes k3s and everything running on it, and cleans up what they left on disk.

If you added more servers, remove k3s on each of them as well:

```bash
sudo /usr/local/bin/k3s-agent-uninstall.sh
```

## Clean up the firewall rules [#clean-up-the-firewall-rules]

Leftover network rules can get in the way of whatever you install next. Flush them:

```bash
sudo iptables -F
sudo iptables -t nat -F
sudo iptables -t mangle -F
sudo iptables -X
```

Or reboot the server, which has the same effect.

## What is not removed [#what-is-not-removed]

* **Packages** the installer added, like `git`, `curl` and the iSCSI tools.
* **The swap file**, if the installer created one: `/swapfile` and its line in `/etc/fstab`.
* **DNS records** at your DNS provider.
* **The GitHub App** Unbind created in your GitHub account. Delete it under GitHub > **Settings** > **Developer settings** > **GitHub Apps**.
* **Backups** in your S3 buckets.

The cleanest way to leave is still to delete the server.
