BigQuery Backup Frequency and Retention: Best Practices


Implementing effective BigQuery backup frequency and retention is crucial for organizations to protect their valuable data from any accidental or purposeful losses. This blog post discusses the best practices for BigQuery backup frequency and retention, which include determining optimal backup intervals, setting up risk-oriented retention plans, and using automation tools for a seamless and sustainable backup process. By adopting these strategies, organizations can safeguard their data, optimize storage costs, and ensure swift data recovery in case of any disruptions or catastrophes. A simple solution is to try Slik Protect, as it automates BigQuery backups and restoration at regular intervals once configured. Users can set it up in less than 2 minutes and be confident that their data is secured, ensuring business continuity.



In the era of big data, organizations are heavily reliant on the data they gather and analyze for decision-making and insights. To remain competitive, it is essential to have a robust and reliable data infrastructure in place. Google BigQuery, a managed, petabyte-scale data warehouse solution, enables organizations to store, manage, and analyze vast amounts of data with ease, making it an attractive choice for many. However, handling such a colossal amount of data comes with its own risks and challenges. To prevent any loss of crucial information, it is imperative to implement proper backup frequency and retention policies for BigQuery. This article discusses best practices for achieving this and the benefits of using an automation tool like Slik Protect for a seamless process.

Understanding the Importance of BigQuery Backup Frequency and Retention

Backup frequency and retention go hand in hand — both are essential components of any data management strategy. Implementing best practices for BigQuery backup frequency and retention ensures that:

  1. All mission-critical data is protected against accidental or intentional losses, hardware failures, or malicious attacks.
  2. Storage costs are optimized by retaining only necessary data and removing obsolete or redundant information.
  3. Data recovery is swift and efficient in case of disruptions or catastrophes, preventing any adverse impact on business continuity and operations.

Identifying Optimal Backup Intervals

Determining the ideal backup intervals for your organization is a critical step in establishing an effective backup strategy. Consider the following factors when deciding the best backup frequency for your BigQuery data:

  1. Mission-critical data: Identify the data that is most crucial to your business operations and ensure that it is backed up more frequently than non-critical data. For instance, financial records, customer data, or intellectual property information may require daily or even hourly backups.
  2. Data change frequency: Determine how frequently your data changes, as this will affect your backup schedule. Highly dynamic datasets may necessitate more frequent backups to prevent the loss of recent changes and maintain the integrity of the data.
  3. Recovery point objective (RPO): RPO refers to the maximum acceptable amount of data loss measured in time. For example, if your RPO is 24 hours, it means you can afford to lose a maximum of 24 hours worth of data. Set your backup intervals accordingly to ensure you meet your RPO in case of data loss.

Implementing Risk-Oriented Retention Plans

A risk-oriented retention plan ensures that data is stored securely and optimally while complying with industry regulations and organizational requirements. Keep the following best practices in mind while designing your BigQuery data retention policy:

  1. Understand the different types of data: Classify your data based on its importance and sensitivity. Mission-critical data and sensitive information should be retained for longer periods to safeguard against losses and ensure compliance with regulatory standards.
  2. Categorize data by risk: Determine the level of risk associated with each data category and adjust retention durations accordingly. For example, datasets containing personally identifiable information (PII) may require longer retention periods due to the increased risk of data breaches and regulatory penalties.
  3. Schedule regular data reviews: Periodically reviewing your data retention policies helps ensure they remain relevant and effective as your organization grows and evolves. Regularly assess your datasets and adjust your retention plans as needed.
