# Receiving and Decrypting Cloud Backup Data

If necessary, the Illumina Support team can provide a backup of your Clarity LIMS data. The data are contained in an encrypted file, which can be downloaded from a secure SFTP server.

### Prerequisites

To receive the backup data file, provide the Illumina Support team with a GNU Privacy Guard (GPG) public key.

For instructions on generating a GPG public key, see the following documentation:

* For Microsoft® Windows®, see [Creating a certificate](https://www.gpg4win.org/doc/en/gpg4win-compendium_12.html).
* For Linux® or Mac®, see [Generating a new GPG key](https://help.github.com/articles/generating-a-new-gpg-key/).

### Receiving and Decrypting your Backup Data

1. After the Illumina Support team has received the GPG public key, they do the following actions:
   * Create a backup file encrypted with the key.
   * Place the backup file on the LIMS SFTP server at sftp.clarity-lims.com.
   * Provide a username and password so you can access your data. The backups are added to the FTP server weekly.
2. After downloading the backup file, there are several tools available to decrypt the data.
   * For Windows, use the **gpg4win** tool. For details, see the [Gpg4win Compendium](https://www.gpg4win.org/documentation.html).
   * For Mac/Linux, use the **GPG** command on the command line. For details, see [Encrypting and decrypting documents](https://www.gnupg.org/gph/en/manual/x110.html).
