Advancing the data protection that your agile, virtualized data center really needs. As long-time technology partners, HPE and Veeam have one goal: to enhance and deliver data protection for virtual environments that really works. Veeam integration with HPE 3PAR StoreServ and StoreVirtual snapshots has been available for many years.You might want to check out this blog with an in-depth demo on HPE and Veeam integration designed to protect virtual environments.

Today we take another significant step in advancing data protection with the announcement of Veeam Availability Suite v9 with HPE StoreOnce Catalyst. Before we get into the specifics of the integration, let’s take a step back to understand why good data protection is crucial as data centers become more agile and virtualized.

Forces of change

The consumerization of IT and business competition have forced the need for “always-on” and instant-access to applications. Data centers are increasingly adopting technologies such as flash to improve application performance, reduce latency, and so on. The backup windows are fast diminishing and the RPO/RTO parameters are drastically changing application recovery criteria. Data protection must evolve. As a result, we see a large portion of IT budget is now directed* toward improving overall application availability by modernizing data protection.


It all begins with 3-2-1 data protection best practicesintegration2_ATSB_shutterstock_127048415_09Sept_sized.jpg

The core tenet of Veeam and HPE solution is the 3-2-1 (3 copies of data on 2 separate media sets and 1 offsite copy) best practices for data availability and protection aligned with business objectives. Here’s how:

  • Step 1: Use storage snapshots to provide rapid protection and recoverability (think low RPO/RTO) without impacting application SLAs. With integration of Veeam and HPE 3PAR StoreServ and StoreVirtual, you can simply create VM-aware application-consistent snapshots on the storage array every few minutes (for more granular restore points) without impacting application SLA (or VM stuns) or burdening hypervisor. You can also instantly recover VMs or application files in minutes from 3PAR/StoreVirtual snapshots. - key for applications with low downtime tolerance.
  • Step 2: Don’t put all your eggs in one basket. Backup your production data. But backing up mountains of data every day (or night) at least once and retaining them longer is not easy or cheap. You need not only a fast backup but also effective data reduction solution. This is where the integration of HPE StoreOnce and Veeam shines through. I’ll elaborate on this shortly.
  • Step 3: Protect against site-wide disaster. Electronically replicate the backups offsite from StoreOnce disk target or copy to StoreEver tape (most economical media for long term retention) and vault it to a secondary location.

What does integration of Veeam and HP StoreOnce Catalyst mean to you?

First, more about HPE StoreOnce and StoreOnce Catalyst.

HPE StoreOnce is the industry-leading disk based deduplication and backup target device. HPE StoreOnce Catalyst is a backup and recovery optimized device type that uses a more efficient protocol than NAS or VTL for faster performance. Another significant advantage of Catalyst is that it controls where the backup data deduplication processing takes place (i.e. application server, backup server or the target device) to optimize the use of available server resources and network bandwidth.


Now let’s focus on the benefits.

  • Benefit #1: 2-in-1 solution: Delivering higher performance and deduplication efficiency! If you had to choose between a left or a right eye which one would you pick? Doesn’t make sense right? Backups were pretty much like that. Prior to the Catalyst-integrated Veeam solution, you had to choose between a backup target optimized for storage (dedupe) efficiency or performance (simple NAS device or a JBOD), but never both. To address this dilemma, some created a tiered architecture with landing zone (non-deduplicating NAS share or a JBOD) for faster backups and recovery and a deduplicating device behind it for long-term retention. It sure worked but it was complex. Why should you compromise on a data protect solution? The integrated Catalyst-Veeam solution simplifies the backup architecture so you can get faster performance as well as higher space savings from StoreOnce’s 4K variable length inline deduplication. With Catalyst, you now have the flexibility to use StoreOnce deduplication on Veeam proxy servers (source side deduplication) which only sends block level increments to StoreOnce appliance thus significantly reducing network bandwidth consumed by backups. You also have the ability to get better storage utilization both within and across multiple Veeam backup jobs while finishing backups faster. Bake your cake and eat it too!
  • Benefit #2: Shorten your backup windows and recover faster. For most of us, full backups every day are not feasible, considering the data growth and the workload impact of backups on production storage. Yet for the fastest restores, we want to use full backups. Veeam addresses this challenge with full backup synthesized from low impact incremental backups. However, synthesizing full backups from incremental backups is challenging for deduplicating backup storage device because of the number of random IO requests (reads and writes) this process generates. While developing this integration, Veeam and StoreOnce engineers optimized Synthetic full backup creation. As a result, you can significantly reduce the amount of data backed up each night by using incremental backups. This means your backups are shorter and the recoveries are faster using full backups.
  • Benefit #3: Architectural flexibility. HPE StoreOnce offers a family of appliances that provides enterprise-grade scalability with capacity from 5.5 TB to 2.2PB. Deploy either as a physical appliance or as a virtual machine (on ESX, Hyper-V, and KVM) aka StoreOnce Virtual Storage Appliance (VSA) on your existing infrastructure. The common architecture across the StoreOnce product family means you can mix and match appliances such as, for example, VSAs at ROBO and physical appliances at the data center to create flexible deployment scenarios. The Catalyst protocol is optimized for WAN backups which means you can provide enterprise grade protection for your virtual machines at ROBO sites. The possibilities are endless.

Hi Srikanth,


Thanks for that, good write up. The link for Rick Vanover's blog seems to dead though?

Hi Joe.

Please try again - the link is now working to Rick's blog: Insights plus use cases for Veeam v9 with HP StoreOnce

We have just received the RTM build of Veeam v9 and have it successfully writing to a StoreOnce Catalyst Store. This integration is a very welcome addition (previously we've been writing to a StoreOnce NAS Share and the Catalyst Performance is greatly increased).

We also backup a lot of physical servers and data at remote sites and use HP Data Protector for this. All of this other data is backed up to many StoreOnce devices and replication is triggered by Data Protector using its Object Copy jobs and that instructs the StoreOnce's to replicate Catalyst Items using replication. This works beautifully!

With Veeam now writing to a StoreOnce Catalyst Store, we are hoping there is a way to import those Catalyst Data Objects that Veeam writes into HP Data Protector so we can replicate the data just like everything else, and also write the data to tape using automated Object Copy jobs. Since we have some backups in Data Protector and some in Veeam we can't have two products trying to control same MSL4048 LTO6 LIbrary, and since Veeam can't touch the data from our physical and remote servers we need Data Protector to control the tape writing.

Is there, or will there be, any way to import data that Veeam has written to a StoreOnce Catalyst Store into Data Protector so we can then carry out operations on that data?


No Catalyst Copy / Replication support in Veeam 9. That is disappointing.,

Hi Shrikanth,

In Rick's post he still recommends landing backups on non-dedupe storage first before moving to dedupe storage. Can part of a StoreOnce be set to non-dedupe to land initial backups? This would enable faster restores? Can you please provide more information around how Catalyst integration solves this problem?

I'm keen on the StoreOnce but business is questioning whether the solution would suit our RTO SLA's and I know deduped backups can take along time to re-hydrate. Veeam recommend non-dedupe landing zone while you are saying that's no longer needed (which if true is great). I'm very worried about purchasing a StoreOnce and finding our restores are extremely slow but by then it's to late.

Some idea of time it would take to restore a 2TB VM for instance or any information along performance, rough RTO times etc would be very helpful.


Hi Andrew.

Thanks for reading our blogs and commenting.

The recommendation in the blog post makes sense if the user is using IVMR and other Veeam vPower NFS features where production workloads will be run temporarily using the using the backup images. For all other use cases there is significant value, in terms of backup space saving, in using StoreOnce Catalyst as the storage for the backup repository. Restores from StoreOnce run close to the backup speeds but be aware that, by definition, all restores require the full backup image to be written to the restore destination whereas with the Veeam 9.0 + StoreOnce Catalyst integration source deduplication can be configured so only the new backup data chunks are written to the backup repository.

Please let us know if you want to discuss some more.

Hi all

What about the 7 restore point limit with Veeam ad Catalyst integration?
