HPE StoreOnce

HPE StoreOnce is a family of scalable, cyber-resilient backup and data deduplication appliances engineered to protect enterprise data assets, minimize secondary storage footprints, and ensure rapid, dependable disaster recovery following ransomware incidents. Utilizing patented HPE StoreOnce Catalyst technology, the platform optimizes data deduplication at the backup source, media server, or target appliance, slashing network bandwidth consumption by up to 95% and significantly accelerating backup and recovery windows across physical and virtualized workloads.

The platform provides robust, hardware-enforced defense against ransomware attacks targeting enterprise backup archives. Key capabilities include Catalyst Copy with immutable data locking, which prevents malicious actors or rogue administrators from deleting, encrypting, or modifying backup data before a defined retention window expires. Additional features include AES-256 data encryption at rest and in flight with enterprise key management, secure data erasure, automated cloud tiering to public cloud object storage (Cloud Bank Storage), and high-availability hardware clustering. By isolating backup repositories behind non-standard, secure protocol interfaces, StoreOnce prevents malware from traversing corporate networks to infect backup repositories.

HPE StoreOnce integrates natively with industry-leading backup applications, including Veeam Backup & Replication, Commvault, Veritas NetBackup, and Micro Focus Data Protector, as well as HPE GreenLake. Primary enterprise use cases include establishing immutable, ransomware-proof backup targets, optimizing multi-site disaster recovery replication, meeting stringent backup retention regulations, and reducing long-term data archiving costs. HPE StoreOnce delivers bulletproof data immutability, extreme deduplication efficiency, and rapid disaster recovery readiness.
