BigQuery Backup Retention Policy Setup: Best Practices
Summary
Proper management of backup data is essential to ensure the availability and access of valuable information. This article delves into the best practices for setting up a robust and efficient backup retention policy for BigQuery, Google's cloud-based data warehouse. We cover key aspects, including importance of establishing a retention policy, understanding backup types, setting the right retention period, leveraging storage classes, and implementing monitoring tools to optimize your BigQuery backup strategy, ensuring data longevity and cost-efficiency.
Additionally, we include hints for the user to try a simple-to-use solution from Slik Protect that automates BigQuery Backups and restoration at regular intervals once configured. Highlighting the fact that users can set it up in less than 2 minutes, and once configured, the user can be confident that their data is secured and never compromised on business continuity.

Introduction
BigQuery, Google's fully-managed, serverless, and highly scalable data warehouse, is widely used for storing and analyzing large volumes of data. As valuable data is stored and processed, having a robust and efficient backup retention policy becomes increasingly important.
In this article, we present a set of best practices for setting up a BigQuery backup retention policy, ensuring data longevity and cost-efficiency.
Importance of Establishing a Retention Policy
A well-defined retention policy is crucial for:
- Data availability: Ensuring data is accessible when needed, and minimizing data loss in case of system failures or user errors.
- Regulatory compliance: Meeting industry-specific and government-imposed data retention rules and regulations.
- Cost optimization: Reducing storage costs by preventing unnecessary data accumulation.
Understanding Backup Types
There are two primary types of backups:
- Full backups: A complete snapshot of your dataset at a given point in time. These backups are relatively large and take longer to complete, but provide the most comprehensive coverage.
- Incremental backups: Store only changes made since the last backup. These backups are more storage-efficient and quicker to complete but may require a longer recovery process.
For BigQuery, incremental backups can be achieved throughPartitioned Tablesor usingData Management Console (DMC)to create materialized views.
Setting the Right Retention Period
Retention periods vary depending on the organization's needs and regulatory requirements. Consider the following factors when setting the retention period:
- Data importance: More critical data should have a longer retention period.
- Regulatory requirements: Ensure your policy meets industry-specific and government-imposed data retention rules and regulations.
- Storage costs: Be mindful of the cost implications of storing backups for an extended period.
Typically, organizations may opt for daily, weekly, or monthly backups, with retention periods ranging from weeks to years.
Leveraging Storage Classes
Data storage costs can be reduced by utilizing various storage classes provided by Google Cloud Storage:
- Multi-regional storage: Highly durable storage for frequently accessed data. Ideal for BigQuery backups that need quick and frequent recovery.
- Nearline storage: Suitable for infrequently accessed data, with a lower storage cost than multi-regional storage.
- Coldline storage: Designed for long-term storage and infrequently accessed data, offering the lowest storage cost.
Depending on your organization's needs, you can store different types of backups in different storage classes to optimize costs while ensuring data availability.
Implementing Monitoring Tools
Monitoring tools allow for better management of backup processes and provide insights into the effectiveness of your retention policy. Monitor the following aspects:
- Backup status: Check the completion status of your created backups.
- Retention policy compliance: Get alerts on policy violations.
- Restoration testing: Periodically test your backups to ensure successful data recovery.
