It's fast and reliable when compared to tape solutions.
Infrastructure Technician at a university with 501-1,000 employees
We previously used Symantec Backup-Exec to LTO-4 tape. We needed a more scalable solution that was faster and allowed replication off-site nightly at a much quicker rate.
Pros and Cons
- "Over 51TB of data is backed up and replicated off-site every week quickly and reliably, compared to the laborious tape archiving solution we had in the past."
- "The web-GUI is not intuitive enough for basic users and offers fairly limited functionality compared to a backup solution such as Veeam or Backup-Exec."

Learn what your peers think about HPE StoreOnce. Get advice and tips from experienced pros sharing their opinions. Updated: March 2026.
885,264 professionals have used our research since 2012.
What was my experience with deployment of the solution?
No issues encountered.
What do I think about the stability of the solution?
Rarely have issues with stability.
What do I think about the scalability of the solution?
No issues when you need to scale up. It's as simple as 'chucking more disks' into the array when the space needs expanding.
How are customer service and support?
Customer Service:
Good from HP, as usual (on a contract).
Technical Support:Good from HP, as usual (on a contract).
Which solution did I use previously and why did I switch?
We previously used Symantec Backup-Exec to LTO-4 tape. We switched because we needed a more scalable solution that was faster and allowed replication off-site nightly at a much quicker rate.
How was the initial setup?
Simple, it was handled by HP.
What about the implementation team?
We had HP do the implementation, with a third party consultancy firm called System Professional. They had exceptional understanding of the entire platform.
What was our ROI?
I cannot put a price on this investment. Suffice it to say that the countless number of man-hours saved not having to deal with tapes every day/week/month is invaluable.
What's my experience with pricing, setup cost, and licensing?
£100,000 including installation, support and maintenance contracts. This also includes two StoreOnce devices - one at our datacentre, and one replica at another campus.
Which other solutions did I evaluate?
No, we have an extensive support contract with HP and were given a heavily discounted educational agreement as opposed to what other vendors such as EMC were offering.
What other advice do I have?
If you work for an educational institution (as I do), the potential long-term savings will easily add up compared to the short-term initial investment. Do your homework and look elsewhere and you will find it difficult to beat the product/service in terms of cost and performance

Sr Backup Administrator with 1,001-5,000 employees
We like the ability to control where the dedupe takes place and the replication between data centers and smaller credit centers.
Pros and Cons
- "We now have faster more reliable backups, easy replication between data centers and smaller credit centers."
- "We’ve experienced data lost. We’ve had three stores go off-line (which were recoverable) and had a disk become corrupt at the service set/couplet level."
What is most valuable?
The ability to control where the dedupe takes place. StoreOnce allows deduplication in three locations; the client, the backup appliance and designated media servers. This flexibility can come in handy especially in smaller shops/data centers. For example, if network bandwidth is the issue you can dedupe at the client, and that reduces the total amount of data that has to be sent over the wire, or if a backup client doesn’t have the horsepower to dedicate CPU and memory to the dedupe process, you can do it at a designated media server (90% of our backups happen that way). Thirdly, at some of our smaller data clusters, our clients needs all their CPU and memory for running apps, and we don’t have a dedicated media server so we let the StoreOnce appliance do the deduplication.
Also, the ease of replicating between the three types of StoreOnce devices.
How has it helped my organization?
Since we went from disk to tape to D2D that’s a huge improvement. We now have faster more reliable backups, easy replication between data centers and smaller credit centers.
What needs improvement?
- Capacity of the B6200 as the capacity has improved/tripled in the 6500
- It would be nice if it dedupelicated per service set instead of by the store
For how long have I used the solution?
I've used it for two years including testing, and in production for 16 months.
What was my experience with deployment of the solution?
The B6200 was designed to ingest data from different networks and we had three. Some we had to do some additional VLAN tagging.
What do I think about the stability of the solution?
We’ve experienced data lost. We’ve had three stores go off-line (which were recoverable) and had a disk become corrupt at the service set/couplet level. The corrupt service set had to be formatted and we lost 40TB of data. Luckily most of it was replicated from another data center.
How are customer service and technical support?
Customer Service:
9/10.
Technical Support:8/10.
Which solution did I use previously and why did I switch?
We didn't have a previous solution.
How was the initial setup?
It was very complex because our setup included six data centers with three types of StoreOnce devices. Replication between multiple sites, and Oracle, Lotus Notes, VMware, SQL, and Exchange online integrations.
What about the implementation team?
We used a vendor team who were 5/10. HP sent their design team, and they were helpful but the StoreOnce product was very new and they were learning the product. We were given bad information which led to a crash.
Which other solutions did I evaluate?
We also looked at Data Domain, and another whose name I can't remember.
What other advice do I have?
Don’t get the B6200 get the 6500 even if you have to start small in terms of storage. You can add on as you need it.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

IT Technical Architect at a university with 501-1,000 employees
It has given us the ability to run data straight from the device in case of a disaster.
Pros and Cons
- "StoreOnce has the following advantages: Fast backup, no need to manage and store tapes, ability to run data straight from the device in case of a disaster, reliable compared to weekly problems with tapes, and the data is replicated to two remote locations."
- "We had one problem when data replication got stuck and we had to ask HP for help."
What is most valuable?
StoreOnce has the following advantages:
- Fast backup
- No need to manage and store tapes
- Ability to run data straight from the device in case of a disaster
- Reliable compared to weekly problems with tapes
- The data is replicated to two remote locations
How has it helped my organization?
We have moved away from tape backup.
For how long have I used the solution?
I've used it for one year.
What do I think about the stability of the solution?
We had one problem when data replication got stuck and we had to ask HP for help.
What do I think about the scalability of the solution?
No issues encountered.
How are customer service and technical support?
Customer Service:
It's very good.
Technical Support:It's very good.
Which solution did I use previously and why did I switch?
We only used a tape solution. We switched because tapes are too slow, prone to mechanical problems, tape management is a burden, and the time taken to do a restore is slow.
How was the initial setup?
It was easy. Also I did HPs StoreOnce training.
What about the implementation team?
HP installed the device for us, and showed us various configuration options. The team was very knowledgeable.
What's my experience with pricing, setup cost, and licensing?
The initial cost was high, however, day to day costs are low.
Which other solutions did I evaluate?
I could not find a better product.
What other advice do I have?
It is worth buying HP installation. It is difficult to estimate how much storage is needed as de-duplication depends on the type of data, so reserve extra money for expansions, and buy a model which can be expanded. Also, the StoreOnce course is very good.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Thanks for the review - StoreOnce is a hidden gem in the HP Storage portfolio? For those that don't know the portfolio well, here's a blog post with a good overview. Be sure to watch the videos too: hpstorage.me/1Ff6fB0

Head of Data Centre at a financial services firm with 501-1,000 employees
The tiering functionality saves the company money; system automatically decides to which storage type the data should be written.
Due to growth, our data centre, including storage, reached its limits. Two key requirements for the new infrastructure were scalability and flexibility, to allow the IT side of mergers to run as efficiently as possible. Reliability with an up-time of at least 99.9 per cent was also essential. Data restore following a technical or logic error needed to be considerably faster than in the past. We also wanted to achieve as high a level of standardisation as possible so we could easily outsource the systems to a housing provider if this became necessary in the future.
Following a detailed tender and selection process, we concluded that an HP Converged Infrastructure could fulfill our requirements. The deciding factor was the way the backup solution worked with the storage system in the fibre channel-based storage network we wanted. The HP Converged Infrastructure consists of two HP 3PAR StoreServ 7200 Storage systems, two HP StoreOnce 4430 backup systems, HP Data Protector software for storing and restoring data, an MSL4048 tape library for long term archiving of data and multiple Brocade SAN switches for the HP BladeSystem for the storage network, increasing the band width from 4GB to 8 GB per second. The HP 3PAR StoreServ 7200 Storage systems were provided with 64 terabytes of storage capacity. These are currently 70 per cent full. That fits with our business requirements. We have enough space for both organic growth as well as for future company purchases. We can also expand the HP 3PAR StoreServ quickly and easily at any time by adding further nodes, which gives us a very high degree of flexibility.
To ensure the high availability of the system,we fitted the HP 3PAR StoreServ 7200 Storage systems with the replication and automatic transparent failover software features. If hardware outages or entire data centre outage happens, Storage services are automatically assumed by other components – without any loss of service. The tiering functionality saves the company money as the HP 3PAR StoreServ 7200 automatically decides to which storage type the data should be written (tiered according to speed and therefore price), depending on data access. We are now starting to use the reporting functionality of the storage solution. We want to control the infrastructure proactively in terms of IT service management. The monitoring and reporting functionalities help us with this.
The entire system has been very stable right from the start – and also very fast. Our customers have noticed from our considerably faster response times that we have completely redesigned our data centre. Today, even the slowest tiering level in the storage system is faster than our old solution. The company intends to achieve further cost savings on storage with its backup solution: The hard drive space required for the databases was reduced by 50 per cent just by using the corresponding adaptor from the HP 3PAR StoreServ 7200 Storage system to Microsoft SQL server. This is because the HP Data Protector software stores the productive database data online to the HP 3PAR StoreServ 7200 Storage system via the connector, without having to create a backup.
We have also implemented further connectors to VMware vCenter and Microsoft Exchange Server. To ensure that the HP 3PAR StoreServ 7200 Storage system will always be up to date, we decided to use HP Proactive Care Services. This service reduces the IT department’s workload as we no longer have to keep track of patches and software upgrades ourselves. HP does this for us. We have already experienced the benefits of this. An HP technician contacted us and updated the system without limiting our operations at all. It went fantastically well. We can also administer the storage with just two employees. That was unthinkable before. We have a high-tech solution in the data centre which will support as we follow the company strategy in the coming years. It is also a great foundation for existing IT projects such as big data and ERP consolidation.

Solutions Architect at a comms service provider with 10,001+ employees
Initial configuration into the network needs improvement but deduplication features are valuable.
Pros and Cons
- "The deduplication is great on this solution, no more TB's of wasted space, send deduplicated backup data over those expensive leased lines saving bandwidth, and so on..."
- "The initial installation and configuration into the network and the integration into the infrastructure needs some improvement, but it's not too difficult if you plan right."
What is most valuable?
The ease of use and configuration once implemented and the deduplication features.
How has it helped my organization?
Before the StoreOnce solution was implemented all kinds of backup solutions and software were being used in this international company, making it very difficult to manage, keep control over the backups, losing data left and right, very unprofessional.
Also a lot of tapes needed to be kept offside, using one of these companies that comes and collects tapes to store in a secure location, this costs the company a lot of money.
Now several StoreOnce appliances sync with each other to take care of the disaster recovery compliancy, remote offices stream deduplicated backup data to the StoreOnce and use the same backup software as all other locations.
What needs improvement?
The initial installation and configuration into the network and the integration into the infrastructure needs some improvement, but it's not too difficult if you plan right.
For how long have I used the solution?
For well over 1 year now.
What was my experience with deployment of the solution?
The deployment of the solution is done by HP, they insisted on it, the initial planning was the task of the client, there were some bumps along the road, but in the end it was deployed rather quickly.
What do I think about the stability of the solution?
No issues during initial config, can't say there were any stability issues.
What do I think about the scalability of the solution?
The scalability is something you need to plan for ahead, the amount of TB you're looking to backup now and how much it would grow in the future. Depending on the outcome of your calculation you need to choose the model accordingly (the higher models allow for more scalability - read higher amount of TB that can be stored).
How are customer service and technical support?
Customer Service:
No issues with customer service, quick and correct.
Technical Support:They could answer all our questions and helped us to get going without too much time and effort.
Which solution did I use previously and why did I switch?
Previously it was a bunch of solutions (backup to disk, to tape, etc) and all kinds of different backup software dispersed over different locations, very unmanageable and lots of issues with backup. It needed to be consolidated and in the meantime it needed to provide the necessary Disaster Recovery abilities. That's why this solution was chosen.
How was the initial setup?
Initial setup was done along with HP, it wasn't overly complex if you know something about backup and the software solution to go along with it, if you have to start from scratch it can be quite the task, it isn't plug and play, there is quite some configuration to be done, you also need to know your backup environments in and out, plan ahead. You need to know what goes where and how it will be replicated.
What about the implementation team?
As mentioned earlier, the solution was implemented along with HP, their level of expertise was above par.
What was our ROI?
Too soon to tell, but initial reports tell us it definitely will save us a lot of money, on tapes and tape handling alone.
Which other solutions did I evaluate?
Yes, some other solutions came across our desk, but I can't remember which ones though. Pretty early on we chose to go with HP StoreOnce.
What other advice do I have?
Read up on the solution, there are a lot of advantages in this product, all depends on your environment, if you are one of those companies that has a lot of tapes and different locations, it could definitely be something for you. The deduplication is great on this solution, no more TB's of wasted space, send deduplicated backup data over those expensive leased lines saving bandwidth, and so on...

I joined this forum looking for the experience of others for backup and SAN solutions. I am more of an expert at Next Generation Firewalls offered today. I see this user is happy with the HP backup solution. Are there reviews somewhere for VEEAM? Also I noticed the several good reviews for HP 3PAR SAN storage. Is there an in depth review for Nimble storage as well to compare? I have researched Nimble, NexGen and Kaminario for the larger SAN projects but have not purchased one of these yet. Thanks
