* `MAILX_ARGS` - Optional. If specified, the content of `/var/log/backup-last.log` is sent via mail after each backup using an *external SMTP*. To have maximum flexibility, you have to specify the mail/smtp parameters by your own. Have a look at the [mailx manpage](https://linux.die.net/man/1/mailx) for further information. Example value: `-e "MAILX_ARGS=-r 'from@example.de' -s 'Result of the last restic backup run' -S smtp='smtp.example.com:587' -S smtp-use-starttls -S smtp-auth=login -S smtp-auth-user='username' -S smtp-auth-password='password' 'to@example.com'"`.

To use rclone as a backend for restic, simply add the rclone config file as a volume with `-v /absolute/path/to/rclone.conf:/root/.config/rclone/rclone.conf`.
Note that for some backends (Among them Google Drive and Microsoft OneDrive), rclone writes data back to the `rclone.conf` file. In this case it needs to be writable by Docker.
If the the container fails to write the new `rclone.conf` file with the error message `Failed to save config after 10 tries: Failed to move previous config to backup location`, add the entire `rclone` directory as volume: `-v /absolute/path/to/rclone-dir:/root/.config/rclone`.
