BigQuery backup scripts

Project description

# bqup

BigQuery backup scripts

## Dependencies

1. [Python BigQuery Client Library](

## Usage

bqup [-p PROJECT_ID] [-d TARGET_DIR] [-fvx]

-p PROJECT_ID, --project PROJECT_ID Project ID to load. If unspecified, defaults to current project in configuration.
-d TARGET_DIR, --dir TARGET_DIR The target directory where the project will be written. Defaults to current timestamp.
-f --force Overwrite target directory if it exists.
-v --verbose Print a summary of the loaded project.
-x --schema Export table schemata as json.

## Development

1. Set up `gcloud` to run with your personal account (aka run with scissors)
1. Set up [application-default]( `gcloud auth application-default login`
1. Install wheel: `pip3 install wheel`
1. Install `bqup` with `pip3 install -e .` (or `python3 develop`)
1. Run `bqup` (see [Usage](#usage))

## Production

**Note: When deploying for a new GCP project, consider using [Cloud Scheduler](**

1. Turn off your host Google Instance.
1. Enable BigQuery on the instance's Cloud API Access Scopes
1. Start the instance.
1. `ssh` into the Google Instance you want to run `bqup` from.
1. Authorize your Compute Instance Account to read from the target BigQuery project.
1. Install `bqup` by cloning this repo and running `pip3 install --user -e .` inside the repo.
1. Run `bqup`
- If it still doesn't work, check in IAM that the service account you are using has BigQuery read access.

### Setting up regular backups

1. On the machine that will run your backups, set up your git config (username, email, the usual).
1. Make a directory to use as the Git repository. For this example, let's use `repo`:

mkdir repo
cd repo
git init

1. Add the remote to the git repository (ideally a GCP repository). For this example, let's use `google`:

git remote add google <url-to-remote-repository>

1. Create a script called `` that follows the following template. For our example, our repository is dedicated to backups, so we just assume that our `HEAD` is the latest and just push gently to `master`.

<path-to-bqup> -p <project-id> -d <path-to-repo>/projects -fv >> <path-to-log-file>
cd <path-to-repo>
date > last-updated.log
git add .
git commit -m "Automated bqup"
git push <remote> <branch>

1. Add this script to your [crontab]( to run as frequently as your heart desires.

## Distribution

- Rebuild the `dist` directory

rm -rf dist
python3 bdist_wheel

- Test upload (optional, needs account)

twine upload -u thinkdatasci --repository-url dist/*

- Final upload

twine upload -u thinkdatasci dist/*
