# Encrypt backups using GPG
The image supports encrypting backups using GPG out of the box.
In case a `GPG_PASSPHRASE` environment variable is set, the backup archive will be encrypted using the given key and saved as a `.gpg` file instead.
Assuming you have `gpg` installed, you can decrypt such a backup using (your OS will prompt for the passphrase before decryption can happen):
```console
gpg -o backup.tar.gz -d backup.tar.gz.gpg
```
