AIandlatency-sensitive analytics workloads increasingly depend on data lakehouses as their underlying data architecture. 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,andperformance 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 operationsandimprove performance.As AWS customers evaluate the growing importance of their Iceberg-based data lakehouses, considerations around protection, resilience,andmigration 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, Commvault is deepening its collaboration with AWS to help customers modernize, protect,andoptimize their cloud-native data.ThroughClumio, Commvault delivers anIceberg-aware, air-gapped cyber resilience solution for AWS –andnow helps automate migration from Iceberg tables registered in the AWS Glue Data Catalog to Amazon S3 Tables, while enabling long-term protectionandrecovery.

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 performanceandsimplify operations. According to AWS, S3 Tables can deliver up to3 times faster query performanceandup to 10 times higher transactions per second compared to Iceberg tables stored in general purpose S3 buckets.Many teams also want to offload undifferentiated heavy lifting – such as compaction, snapshot management,andunreferenced file cleanup – while reducing overall storageandquery costs.However, existing AWSandcommunity guidance, such as AWS’s migration framework, outlines a manual, multi-step process requiring custom scriptingandorchestration. Migrating data while maintaining schema, metadata,andversion history can be time-consuminganderror-prone,andmost 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 migrationandresilience capability that modern data lakehouses have been missing.

How Clumio Simplifies MigrationandProtection
Clumio for Apache Iceberg on AWS 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,andretention capabilities that help support compliance requirements – extending Commvault’s leadership in cloud-native cyber resilience.Migrationandprotection 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,Clumiooffers a publicly availableTerraform module 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, accidental deletion, malicious or mistaken changes,andaccount compromise can disrupt AIandanalytics pipelinesandlead to costly reprocessing. Clumio helps customers mitigate these risks withimmutable, air-gapped backupsand flexible recovery options across accounts, regions, snapshots,andpoints in time.

How It Works – From Backup to Restore
The migration process using Clumio follows a straightforward backup-and-restore workflow, designed to minimize effortandhelp maintain Iceberg table integrity.Step 1: Connect with the Commvault team for migration program reviewandapproval. Please contact us.Step 2: Discoverandback 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 forandhelps provide transactionally consistent Iceberg recovery across accounts, regions,andsnapshots.To see the full migration workflow in action – including Iceberg discovery, backup selection, snapshot options,andrestoration 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,andsnapshot 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.
| DIY scripts/ open source tools |
Custom scripts using Athena or Glue APIs to copy dataandmetadata | Best suited for teams with scripting expertiseandcustom migration requirements |
| Native AWS processes/ snapshots |
AWS documentationandcommunity guides outline snapshot-based or query-driven migrations | Suitable for teams using native AWS servicesandmanaging multi-step migration processes |
| Clumio | SaaS-based, Iceberg-aware backupandrecovery solution for AWS | Simple, Iceberg-aware migration workflow that helps preserve metadataandsnapshot lineage while integrating ongoing protection |
