Serverless cloud-native backup and recovery for AWS and Google Cloud data with air-gapped immutable protection against ransomware.

Clumio is a cloud-native data protection platform founded in 2017 by Poojan Kumar, Kaustubh Patil, and Woon Ho Jung. The company built a SaaS-based backup and recovery service focused on AWS and Google Cloud workloads, addressing a market where cloud-native organizations needed ransomware-resistant, air-gapped backup strategies. By 2024, Clumio had achieved 4x year-over-year ARR growth and protected over 100 petabytes of data for hundreds of customers, including Atlassian, LexisNexis, Duolingo, Cava, and Warner Bros.

Discovery. The platform specializes in immutable, serverless backups with instant recovery capabilities for S3, DynamoDB, RDS, Aurora, and other AWS native services, along with Microsoft 365 protection. Clumio raised $261 million across five funding rounds, most recently a $75 million Series D in February 2024 led by Sutter Hill Ventures.

In June 2024, co-founder Poojan Kumar stepped down as CEO, replaced by Rick Underwood, who had joined as Chief Revenue Officer nine months prior. Underwood brought over a decade of go-to-market experience from Snowflake and EMC. The company's momentum shifted dramatically when Commvault acquired Clumio for $47 million in September 2024—an 82 percent discount to its latest funding valuation.

The deal marked a strategic consolidation in the enterprise backup sector, positioning Clumio's AWS expertise within Commvault's broader cyber resilience platform. By early 2026, Commvault announced Clumio's expansion to Google Cloud Storage with immutable backup protection for cloud-native datasets powering AI workloads, signaling continued product evolution within the larger organization.

Strengths and what to watch

Strengths

Agentless, serverless architecture with zero infrastructure maintenance; customers report setup in days rather than weeks
Air-gapped immutable backups with composite encryption prevent ransomware propagation; 86 NPS and 5-star AWS Marketplace rating attest to effectiveness
Rapid recovery at petabyte scale with S3 Instant Access feature allows applications to stay online during incidents without waiting for full restore

Watch for

Acquisition by Commvault at steep discount ($47M for a company that raised $261M) signals struggle with independent unit economics or market saturation; integration losses and talent attrition risk in year one
Single-cloud heritage: early strengths centered on AWS; Google Cloud expansion (April 2026) still in early access, showing late entry to multi-cloud market that competitors dominated years prior
Reporting granularity and advanced workload coverage gaps noted by Gartner reviewers; per-account onboarding model creates cost friction at scale

Frequently Asked Questions

What is Clumio?

Clumio is a serverless, cloud-native data protection platform providing backup and recovery for AWS and Google Cloud workloads. Founded in 2017, it specializes in ransomware-resistant, air-gapped immutable backups with instant recovery capabilities for databases, storage, and business applications without requiring infrastructure.

How does Clumio protect against ransomware?

Clumio uses air-gapped, immutable backups with composite encryption that prevent ransomware from propagating to backup copies. Its serverless architecture separates backup storage from production systems, ensuring threat actors cannot encrypt or delete protected data even if they compromise primary infrastructure.

What AWS services does Clumio backup?

Clumio provides agentless backup and recovery for AWS S3, DynamoDB, RDS, and Aurora databases. Its serverless architecture supports rapid recovery with S3 Instant Access, allowing applications to stay online during incidents without waiting for full restore completion across petabyte-scale deployments.

What is an immutable backup?

An immutable backup is a copy of data that cannot be modified, encrypted, or deleted after creation. Once written, immutable backups remain locked from alteration, making them a strong defense against ransomware attacks that try to corrupt or encrypt backup files to prevent recovery.

Does Clumio work with Google Cloud?

Yes, Clumio extended its platform to Google Cloud Storage in April 2026, now offering air-gapped immutable backups for cloud-native datasets powering AI workloads. This expansion brings rapid recovery capabilities previously limited to AWS environments, with general availability targeted for summer 2026.

Who acquired Clumio and why?

Commvault acquired Clumio in September 2024 for $47 million. The acquisition consolidated Clumio's cloud-native AWS expertise and ransomware protection capabilities into Commvault's broader cyber resilience platform, positioning the combined entity to serve enterprise backup and recovery requirements across cloud deployments.
