Collaborate effectively with partners and benefit from robust data management capabilities
The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Technical support is quite good."
"With 3PAR and with StoreOnce, we kind of have an end to end solution for the customer."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"Due to high speed and multiple simultaneous backup sessions our backup window is reduced remarkably, data throughputs are mentioned as follows: Up to 100 TB/hr of backup performance with StoreOnce Catalyst, up to 40 TB/hr of native backup performance, up to 40 TB/hr of restore performance."
"The product has really improved the backup and restore for our infrastructure."
"The support for this solution is the best in our country."
"The initial setup process is simple."
"For anyone who is looking for a long-term archive, as well as a backup solution, this is the ideal product."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"I would rate QoreStor a ten out of ten for what it offers for the price."
 

Cons

"I don't see any new features that we could want or anything that could be done along those lines. Just that we need a bigger machine, so more speed."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."
"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."
"Scalability can become an issue once you grow past the capacity of a single cluster pair."
"Segmentation was one of the requirements. The HP team promised us that it is possible, but it wasn't available."
"We have had some issues. We are working with HPE to solve all the issues."
"The one issue I have is the maintenance package – it's very expensive."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"The ransomware protection of QoreStor could use improvement."
"The setup of the software is definitely not the easiest thing in the world."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
 

Pricing and Cost Advice

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"The product's pricing is medium."
"To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The price of the product is reasonable."
"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."
"The cost of HPE StoreOnce is very expensive."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
