Bahub API client

Bahub is an automation tool for uploading and restoring backups. Works in shell, can work as a docker container in the same network with scheduled automatic backups of other containers, or can work as an UNIX daemon on the server without containerization.

Contents:

• Configuration reference
  • Environment variables
  • Application configuration
• Basic usage
  • Sending a backup
  • Listing stored backups
  • Restoring a backup
  • Recovery from disaster
  • Making a snapshot of multiple services at once
• Monitoring errors with Sentry
• Notifications

Setup

Bahub can be running as a separate container attached to docker containers network or manually as a regular process. The recommended way is to use a docker container, which provides a working job scheduling, installed dependencies and preconfigured most of the things.

Using docker container

There exists a bahub tag on the docker hub container, wolnosciowiec/file-repository:bahub You can find an example in “examples/client” directory in the repository.

docker-compose.yml

version: "2"
services:
    backup:
        image: wolnosciowiec/file-repository:bahub
        volumes:
            - "./cron:/cron:ro"
            - "./config.yaml:/bahub.conf.yaml:ro"
            - "/var/run/docker.sock:/var/run/docker.sock"
        environment:
            - BACKUPS_ENCRYPTION_PASSPHRASE=some-very-long-passphrase-good-to-have-there-64-characters-for-example
            - BACKUPS_TOKEN=111111-2222-3333-4444-55555555555555
            - BACKUPS_REDIS_COLLECTION_ID=12345678-cccc-bbb-aaa-1232313213123
            - COMPOSE_PROJECT_NAME=test_client

    redis:
        image: redis:3-alpine
        volumes:
            - ./redis:/data
        command: "redis-server --appendonly yes"

/cron

# schedule REDIS server backup on every Monday, 02:00 AM
0 2 * * MON bahub backup some_redis_storage

/bahub.conf.yaml (see: Configuration reference)

accesses:
    some_server:
        url: http://api.some-domain.org
        token: "${BACKUPS_TOKEN}"

encryption:
    my_aes:
        passphrase: "${BACKUPS_ENCRYPTION_PASSPHRASE}"
        method: "aes-128-cbc"

backups:
    some_redis_storage:
        type: docker_volumes
        container: "${COMPOSE_PROJECT_NAME}_redis_1"
        access: some_server
        encryption: my_aes
        collection_id: "${BACKUPS_REDIS_COLLECTION_ID}"
        paths:
            - "/data"

Note: It’s very important to specify the project name in docker-compose with “-p”, so it will have same value as “COMPOSE_PROJECT_NAME”. You may want to add it to .env file and reuse in Makefile and in docker-compose.yml for automation*

Using bare metal

Use Python’s PIP to install the package, and run it.

pip install bahub
bahub --help
