…e on Elastic Metal description: Learn how to recover and download backups of your data from a Scaleway Elastic Metal server using rescue mode with SFTP content: h1: How to rescue and recover your data using rescue mode paragraph: Learn how to recover and download backups of your data from a Scaleway Elastic Metal server using rescue mode with SFTP. tags: recovery rescue data rescue-mode dates: validation: 2025-04-01 posted: 2025-04-01 categories: - elastic-metal-serrs --- If your server encounters issues but does not have a hardware failure, you can still recover your data using rescue mode, regardless of whether you are using Windows or Linux. <Macro id="requirements" /> - A Scaleway account logged into the [console](https://console.scaleway.com) - A [created](/elastic-metal/how-to/create-server/) and [installed](/elastic-metal/how-to/install-server/) Elastic Metal server ## Booting into rescue mode 1. Follow [these instructions](/elastic-metal/how-to/use-rescue-mode/) to start your server in rescue mode (emergency system) via the Scaleway console. 2. Log into your server using one of the following methods: - [PuTTY](http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe) on [Windows](/elastic-metal/how-to/connect-to-server/#how-to-connect-to-an-elastic-metal-server-from-windows) - `ssh` from a terminal on [Linux or macOS](/elastic-metal/how-to/connect-to-server/#how-to-connect-to-an-elastic-metal-server-from-osx-mac-and-linux). <Message type="tip"> The rescue mode credentials (username and password) are displayed in your Scaleway console. </Message> ## Gaining root access By default, you are logged in as a regular user in rescue mode and may not have permission to execute all necessary commands. 1. Switch to the `root` account by typing the following command and pressing Enter: ```bash sudo su ``` 2. Enter the rescue user password displayed in the Scaleway console and press Enter. <Message type="tip"> For security reasons, the password will not be visible when typing. </Message> ## Mounting partitions To access your data, you need to mount your server’s partitions in rescue mode. If this step succeeds, you can likely recover your files. 1. As the `root` user, run the following command to mount all partitions: ```bash mountall.sh ``` The partitions will be mounted in the `/mnt` directory. <Message type="note"> You may encounter errors such as `swap cannot be mounted` or `many partitions do not exist`. These can be safely ignored. </Message> ## Recovering your data You can recover your data by downloading it directly to your local computer via SFTP. <Message type="important"> Exercise caution when editing your data in rescue mode. The `root` user has full permissions, including the ability to irreversibly delete files. </Message> ### Backing up data to your personal computer (via SFTP) You can use an SFTP client like [FileZilla](https://filezilla-project.org/) to download data from your server. 1. Open FileZilla and fill in the following details: - **Host**: Your server’s IP address - **Username**: Rescue mode username (e.g., `em-XXXX`) - **Password**: Rescue mode password - **Port**: 22 <Message type="tip"> These details are available in your console once rescue mode is active. </Message> #### Example configuration <Lightbox src="sftp.webp" /> Your data will be located in the `/mnt`, `/sda1`, or `/sda` directories. You can download it before reinstalling the server or transferring data to another server. <Message type="tip"> If you encounter difficulties, consider contacting a [certified outsourcer](https://www.scaleway.com/en/dedibox/outsourcing/) for professional data recovery. </Message>
