Configuration

GoBackup will read config from following paths:

~/.gobackup/gobackup.yml
/etc/gobackup.yml

You must use YAML (opens in a new tab) format.

Config file example

web:
  # host: your-host.com
  # port: 2703
  username: <your-name>
  password: <your-web-ui-password>
models:
  # special a model name
  model_name1:
    before_script: |
      # Run script before this model perform backup.
      echo "before script"
    after_script: |
      echo "after script"
    # config compress
    compress_with:
      # compress type
      type: tgz
    split_with:
      # Split backup file into multiple files, each file in 1gb.
      chunk_size: 1g
    # storage
    storages:
      ftp:
        # storage type
        type: ftp
        # other config for this storage type
        host: ftp.your-host.com
        username: ...
        password: ...
    # database source support multiple instance
    databases:
      # special a database name
      my_app1:

        type: mysql
        # other config for this database type
        host: localhost
        database: my_app_production

    compress_with:
      type: tgz
    default_storage: local_a
    storages:
      local_a:
        type: local
        path: /data/backups/my_app2
      cloud_s3:
        type: s3
        keep: 20
        bucket: your-bucket
        region: ap-southeast-1
        path: backups
        access_key_id: xxxxx
        secret_access_key: xxxxxxxx

ENV variables

since: 1.6.0

GoBackup supports to use ENV variables in config, to keep secrets info more secure.

Use $ENV_KEY or ${ENV_KEY} to get ENV variables.

For example:

models:
  example:
    databases:
      postgresql:
        type: postgresql
        database: demo
        username: $POSTGRESQL_USERNAME
        password: $POSTGRESQL_PASSWORD
    storages:
      s3:
        type: s3
        bucket: gobackup-test
        region: ap-southeast-1
        path: backups
        access_key_id: $AWS_ACCESS_KEY_ID
        secret_access_key: ${AWS_SECRET_ACCESS_KEY}

Now you can set ENV in your bash or in .env file.

POSTGRESQL_USERNAME=postgres
POSTGRESQL_PASSWORD=this-is-my-password
AWS_ACCESS_KEY_ID=xxxxxx
AWS_SECRET_ACCESS_KEY=xxxxxxxxxxx
