# Backup to SSH remote server


As described for s3 backup section, to change the storage of your backup and use SSH Remote server as storage. You need to add `--storage ssh` or `--storage remote`.
You need to add the full remote path by adding `--path /home/jkaninda/backups` flag or using `REMOTE_PATH` environment variable.

{: .note }
These environment variables are required for SSH backup `SSH_HOST`, `SSH_USER`, `SSH_REMOTE_PATH`, `SSH_IDENTIFY_FILE`, `SSH_PORT` or `SSH_PASSWORD` if you dont use a private key to access to your server.
Accessing the remote server using password is not recommended, use private key instead.

```yml
services:
  mysql-bkup:
    # In production, it is advised to lock your image tag to a proper
    # release version instead of using `latest`.
    # Check https://github.com/jkaninda/mysql-bkup/releases
    # for a list of available releases.
    image: jkaninda/mysql-bkup
    container_name: mysql-bkup
    command: backup --storage remote -d database
    volumes:
      - ./id_ed25519:/tmp/id_ed25519"
    environment:
      - DB_PORT=3306
      - DB_HOST=mysql
      #- DB_NAME=database
      - DB_USERNAME=username
      - DB_PASSWORD=password
      ## SSH config
      - SSH_HOST="hostname"
      - SSH_PORT=22
      - SSH_USER=user
      - REMOTE_PATH=/home/jkaninda/backups
      - SSH_IDENTIFY_FILE=/tmp/id_ed25519
      ## We advise you to use a private jey instead of password
      #- SSH_PASSWORD=password

    # mysql-bkup container must be connected to the same network with your database

### Recurring backups to SSH remote server

As explained above, you need just to add required environment variables and specify the storage type `--storage ssh`.
You can use `--cron-expression "* * * * *"` or  `BACKUP_CRON_EXPRESSION=0 1 * * *` as described below.

```yml
services:
  mysql-bkup:
    # In production, it is advised to lock your image tag to a proper
    # release version instead of using `latest`.
    # Check https://github.com/jkaninda/mysql-bkup/releases
    # for a list of available releases.
    image: jkaninda/mysql-bkup
    container_name: mysql-bkup
    command: backup -d database --storage ssh --cron-expression "0 1 * * *"
    volumes:
      - ./id_ed25519:/tmp/id_ed25519"
    environment:
      - DB_PORT=3306
      - DB_HOST=mysql
      - DB_NAME=database
      - DB_USERNAME=username
      - DB_PASSWORD=password
      ## SSH config
      - SSH_HOST="hostname"
      - SSH_PORT=22
      - SSH_USER=user
      - REMOTE_PATH=/home/jkaninda/backups
      - SSH_IDENTIFY_FILE=/tmp/id_ed25519
     # - BACKUP_CRON_EXPRESSION=0 1 * * * # Optional
      #Delete old backup created more than specified days ago
      #- BACKUP_RETENTION_DAYS=7
      ## We advise you to use a private jey instead of password
      #- SSH_PASSWORD=password
     # mysql-bkup container must be connected to the same network with your database
