# 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
|
|
```
