Among AWS customers building these environments, Apache Iceberg has become one of the fastest-growing table formats on Amazon S3, providing the transactional consistency, schema evolution, and performance needed for modern analytics. --- AWS customers manage Iceberg tables today through the AWS Glue Data Catalog or adopt AWS’s fully managed option, Amazon S3 Tables, to streamline operations and improve performance. --- As AWS customers evaluate the growing importance of their Iceberg-based data lakehouses, considerations around protection, resilience, and migration to Amazon S3 Tables naturally become part of that planning. Many teams are now looking for a simple, reliable way to move from Glue-managed Iceberg tables to S3 Tables while strengthening the protection of these critical datasets. --- As [AWS’s 2025 Global Storage Partner of the Year](https://www.commvault.com/news/commvault-awarded-2025-aws-global-storage-partner-of-the-year), Commvault is deepening its collaboration with AWS to help customers modernize, protect, and optimize their cloud-native data. --- Through [Clumio](https://www.commvault.com/clumio), Commvault delivers an [Iceberg-aware, air-gapped cyber resilience solution for AWS](https://www.commvault.com/news/commvault-delivers-industry-first-cyber-resilience-for-ai-data-lakehouses) – and now helps automate migration from Iceberg tables registered in the AWS Glue Data Catalog to Amazon S3 Tables, while enabling long-term protection and recovery. You can start your free trial in the [AWS Marketplace](https://aws.amazon.com/marketplace/pp/prodview-hdul2n6jr5dou). --- ### **The Challenge: Limited Options for Moving to S3 Tables** --- Organizations are increasingly evaluating migrations from Glue-managed Iceberg tables to fully managed Amazon S3 Tables to improve data lake performance and simplify operations. According to AWS, S3 Tables can deliver up to [3 times faster query performance and up to 10 times higher transactions per second](https://aws.amazon.com/about-aws/whats-new/2024/12/amazon-s3-tables-apache-iceberg-tables-analytics-workloads/) compared to Iceberg tables stored in general purpose S3 buckets. --- Many teams also want to offload undifferentiated heavy lifting – such as compaction, snapshot management, and unreferenced file cleanup – while reducing overall storage and query costs. --- However, existing AWS and community guidance, such as [AWS’s migration framework](https://aws.amazon.com/solutions/guidance/migrating-tabular-data-from-amazon-s3-to-s3-tables/), outlines a manual, multi-step process requiring custom scripting and orchestration. Migrating data while maintaining schema, metadata, and version history can be time-consuming and error-prone, and most current approaches focus on replication rather than Iceberg-aware recovery or rollback. --- Clumio’s migration support for Apache Iceberg tables provides the Iceberg-aware, enterprise-grade migration and resilience capability that modern data lakehouses have been missing. [Request a demo](https://www.commvault.com/clumio/request-demo) to see how Clumio streamlines your migration. --- ### **How Clumio Simplifies Migration and Protection** --- [Clumio for Apache Iceberg on AWS](https://www.commvault.com/clumio/workloads/apache-iceberg) helps automate migration from Iceberg tables registered in the AWS Glue Data Catalog to Amazon S3 Tables, while simultaneously enabling long-term protection for these modern data lakehouse assets. --- The same Iceberg-aware platform provides air-gapped, immutable backups, isolated recovery points, point-in-time or snapshot-level restores, and retention capabilities that help support compliance requirements – extending Commvault’s leadership in cloud-native cyber resilience. --- Migration and protection work hand in hand: --- - Help protect Iceberg tables registered in the AWS Glue Data Catalog. - Restore as fully managed Amazon S3 Tables. - Continue helping protect those Iceberg tables with Clumio’s cyber resilience capabilities. --- For teams that prefer Infrastructure-as-Code deployment, [Clumio](https://www.commvault.com/clumio) offers a publicly available [Terraform module](https://registry.terraform.io/modules/clumio-code/aws-template/clumio/latest) that supports Apache Iceberg. --- As AWS customers adopt Amazon S3 Tables, protecting these modern data assets becomes even more important. Threat vectors such as [ransomware](https://www.commvault.com/explore#topic-ransomware), accidental deletion, malicious or mistaken changes, and account compromise can disrupt AI and analytics pipelines and lead to costly reprocessing. Clumio helps customers mitigate these risks with [immutable, air-gapped backups](https://www.commvault.com/use-cases/immutability-and-storage) and flexible recovery options across accounts, regions, snapshots, and points in time. For a deeper look at why data lakehouses need purpose-built protection, see [Closing the Gap in Data Lakehouse Protection](https://www.commvault.com/blogs/closing-the-gap-in-data-lakehouse-protection). --- ### **How It Works – From Backup to Restore** --- The migration process using Clumio follows a straightforward backup-and-restore workflow, designed to minimize effort and help maintain Iceberg table integrity. --- **Step 1:** Connect with the Commvault team for migration program review and approval. Please [contact us](https://www.commvault.com/clumio/contact-us-today). --- **Step 2:** Discover and back up Iceberg tables registered in the AWS Glue Data Catalog, with underlying data stored in S3, using Clumio. --- **Step 3:** Restore Iceberg table backups – whether the full snapshot history, a selected subset, or a specific point-in-time version – as Amazon S3 Tables in any account or region. --- **Step 4:** Enable incremental backups to maintain protection for your new Amazon S3 Tables. --- Clumio’s architecture helps reduce the need for and helps provide transactionally consistent Iceberg recovery across accounts, regions, and snapshots. --- To see the full migration workflow in action – including Iceberg discovery, backup selection, snapshot options, and restoration to Amazon S3 Tables – watch the demo video embedded below. It walks through the entire backup-and-restore flow end to end, showing how Clumio handles the data, metadata, and snapshot migration with no manual configuration required. --- --- ### **Comparing Migration Options** --- Most migrations to Amazon S3 Tables today depend on manual scripts or native tooling. Here’s how those methods compare against Clumio’s Iceberg-aware approach. --- | **Method** | **Description** | **Key Considerations** | |---|---|---| | **DIY scripts/ open source tools** | Custom scripts using Athena or Glue APIs to copy data and metadata | Best suited for teams with scripting expertise and custom migration requirements | | **Native AWS processes/ snapshots** | AWS documentation and community guides outline snapshot-based or query-driven migrations | Suitable for teams using native AWS services and managing multi-step migration processes | | **Clumio** | SaaS-based, Iceberg-aware backup and recovery solution for AWS | Simple, Iceberg-aware migration workflow that helps preserve metadata and snapshot lineage while integrating ongoing protection | --- [Request a demo](https://www.commvault.com/clumio/request-demo) to learn how Clumio simplifies migration at scale. --- ### **Why This Matters for AWS Customers** --- As AWS customers modernize their data lakehouses, they need a simple, scalable way to migrate Iceberg tables to Amazon S3 Tables and protect them against operational and cyber risks.
