Leveraging Snowflake’s Time Travel for Data Recovery and Analysis

About the Client:

A leading commercial real estate firm with a robust portfolio of office, retail, and industrial properties across major metros. Their operations are data-intensive, relying on rich datasets like acquisition pipelines, leasing terms, tenant data, financial KPIs, and valuation models.

Background:

The client had recently migrated their analytics and operational workloads to Snowflake, consolidating fragmented systems and dramatically improving query speed. Teams relied on real-time and frequently updated datasets, but the high data velocity introduced issues around data integrity, rollback, and historical analysis. The absence of efficient historical data access posed barriers to agility and compliance.

Challenge:

The client faced recurring issues that limited their ability to recover and analyze data effectively:

  • Accidental data overwrites or deletions caused by multiple users and automated pipelines
  • Inability to easily answer questions like “What did this dataset look like last Tuesday?”
  • Manual and inefficient rollback processes for erroneous loads or transformations
  • Difficulty testing “what-if” scenarios without risking live data
  • Gaps in maintaining immutable historical records for audits and regulatory compliance

Solution:

To solve these issues, our team implemented Snowflake’s native Time Travel feature, embedding it into both operational workflows and governance processes.

Awareness & Education

  • Introduced Time Travel concepts to data engineers, analysts, and stakeholders
  • Conducted hands-on workshops on syntax, retention, and real estate-specific use cases

Operational Integration

  • Created playbooks for instant recovery using UNDROP and CLONE AT
  • Enabled analysts to query datasets as of specific timestamps for robust comparisons
  • Instituted validation workflows comparing transformed data with historical versions
  • Empowered data science teams to run zero-copy experiments without impacting production

Governance & Optimization

  • Reviewed and tailored Time Travel retention policies (up to 90 days) for cost-effective historical access
  • Integrated Time Travel with audit workflows, reducing compliance overhead

Ensured role-based access control for secure use of Time Travel functions

Outcome:

By embedding Time Travel, the client unlocked major operational and strategic gains:

  • 90% faster recovery from accidental drops and corruptions, minimizing disruption
  • Effortless historical comparisons enabled sharper valuations and better decision-making
  • Boosted trust in data integrity, with every change trackable and reversible
  • Accelerated experimentation, allowing safe, instant cloning for sandbox testing
  • Streamlined compliance, with immutable historical states available on demand
  • Cost-efficient versioning compared to traditional snapshots or backups
