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.
Independent Software Vendor (ISV) Controlled Data Immutability (ISV-DI)
Together with HPE StoreOnce Independent Software Vendor (ISV) Controlled Data Immutability (ISV-DI), Veeam Backup & Replication allows you to prohibit deletion of data from the HPE StoreOnce deduplicating storage appliances by making that data temporarily immutable. This is required for improved security: immutability protects your data from loss as a result of malware activity or unplanned actions.
You can enable the immutability feature and specify the immutable period when adding or editing the HPE StoreOnce backup repository. For more information, see Configure Backup Repository Settings. Once imposed, immutability prohibits deletion of data from the deduplicating storage appliance until the immutability expiration date comes. Note that if you enable immutability and Veeam Backup & Replication does not start a new backup chain and still continues the chain, the whole backup chain is marked as immutable. Once you disable immutability, newly created backups are not marked as immutable.
In many respects, HPE StoreOnce with enabled immutability works similarly to the hardened repository. For more information on how repositories with immutability operate as a part of a scale-out backup repository, see Hardened Repository as Performance Extent. For more information on how retention periods set in jobs and in the deduplicating storage appliance correlate, see Retention Scenarios.
Fixed Block Chunking
Together with fixed block chunking, Veeam Backup & Replication improves performance when creating incremental and synthetic full backup files. Fixed block chunking improves performance up to 4-5 times compared to variable chunking,
Veeam Backup & Replication supports fixed block chunking functionality for HPE StoreOnce software version 4.3.2 or later. To be able to use this functionality in Veeam Backup & Replication, check that the Align backup file data blocks option is enabled in the repository settings.
Fixed block chunking is supported for the following types of backups:
- Backups of VMware vSphere virtual machines created by Veeam Backup & Replication
- Backups of Microsoft Hyper-V virtual machines created by Veeam Backup & Replication
- Backups of virtual and physical machines created with Veeam Agent for Microsoft Windows, Veeam Agent for Linux, Veeam Agent for Oracle Solaris or Veeam Agent for IBM AIX
- Backups of Nutanix AHV virtual machines created by Veeam Backup for Nutanix AHV
- Backups of RHV VMs created by Veeam Backup for RHV
