HPE StoreOnce
Fast backups, faster recovery, and far less storage to pay for
Overview
HPE StoreOnce is a purpose-built backup appliance that shrinks the cost of protecting your data while making recovery quick and dependable. Industry-leading deduplication cuts how much storage you need, and built-in security features like immutable backups and encryption keep your data safe from ransomware. It works with the backup software you already run and scales from a single edge site to the largest data center.

Why HPE StoreOnce
Cut storage costs with deduplication
Fine-grained 4 KB deduplication and compression deliver data-reduction ratios of up to 60:1, so you store and pay for a fraction of the raw backup data.
Built-in cyber resilience
Immutable backups, encryption, dual authorization, and air-gapped copies guard your data against ransomware and keep it recoverable when an attack hits.
Recover fast to meet tight windows
High-performance backup and rapid restore, including all-flash options, help you hit demanding recovery point and recovery time targets.
Works with your backup software
Tight integration with Veeam, Commvault, Veritas NetBackup, and standard NAS protocols lets you protect your stack without ripping anything out.
Extend backups to the cloud
Cloud Bank Storage moves only unique, deduplicated data to object storage for low-cost long-term retention, without changing your existing workflows.
Manage everything from one place
Centralized monitoring and automated management give you a single view across systems, from a single edge appliance to the full enterprise.
