HPE StoreOnce Supported Features

The HPE StoreOnce Catalyst technology offers a set of features for advanced data processing. Veeam Backup & Replication supports the following features:

Synthetic Full Backups

HPE StoreOnce Catalyst improves synthetic full backup file creation and transformation performance. When Veeam Backup & Replication creates or transforms a synthetic full backup, HPE StoreOnce does not physically copy data between the existing backup chain and the target full backup file. Instead, it performs a metadata-only operation — updates pointers to existing data blocks on the storage device. As a result, the operation completes much faster. This mechanism helps improve performance of primary backup jobs and backup copy jobs that are scheduled to create periodic archive full backups (GFS).

Accelerated Data Recovery

Integration with HPE StoreOnce improves data recovery performance for different restore scenarios: Instant Recovery, file-level recovery and application items recovery with Veeam Explorers.

WAN-based Catalyst Store Support

Veeam Backup & Replication provides advanced support for WAN-based HPE Catalyst stores. If a WAN connection to HPE StoreOnce is weak, you can instruct Veeam Backup & Replication to compress VM data and calculate checksums for data blocks going from the source side to HPE StoreOnce.

HPE StoreOnce Replication

HPE StoreOnce replication improves copying data between two HPE StoreOnce backup repositories. For more information on copying, see Creating Backup Copy Jobs for HPE StoreOnce Repositories.

Supported Protocols

Veeam Backup & Replication supports HPE StoreOnce storage systems working over the following protocols:

  • TCP/IP protocol: Veeam Backup & Replication communicates with the HPE StoreOnce appliance by sending commands over the LAN.
  • Fibre Channel protocol: Veeam Backup & Replication communicates with the HPE StoreOnce appliance by sending SCSI commands over Fibre Channel.

Data processing over Fibre Channel (FC) connectivity enables local area network-free backup to HP StoreOnce, eliminates the load from backup activities and increases availability of LAN resources to production workloads.


Currently, Veeam Backup & Replication does not support HPE StoreOnce data immutability.
