Apache Airflow: Mastering Backup Automation
As data volumes continue to grow, backup processes can become increasingly complex and chaotic. Apache Airflow provides a powerful solution to this problem, allowing users to create repeatable jobs, define retention rules, and store data in encrypted repositories. In this article, we will walk through a hands-on backup checklist using Apache Airflow, covering jobs, reports, and test restores.
Understanding Apache Airflow Backup Capabilities
Apache Airflow is a popular open-source platform for automating workflows and data processing. Its backup capabilities make it an attractive alternative to expensive backup suites. With Airflow, users can create custom backup jobs, schedule them to run at specific times, and store data in a variety of locations, including local and offsite repositories.
Airflow’s backup features include:
