HPE Product Manager at a tech services company with 51-200 employees
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

"The most valuable feature of the solution is that the tool provides good value for somebody who needs an affordable and reliable storage solution."
"We can backup our exchange server, we can backup our files, and it just works without being overly complex either."
"The most valuable features are the deduplication and compression capabilities."
"The interface is very user-friendly."
"The solution is stable."
"Technical support is quite good."
"In terms of the way that we feel, or the way that I feel about StoreOnce, I think it definitely provided us with the opportunity to give the business something it never had before, and that is a true guarantee to the data that we have."
"The deduplication feature is awesome; the storage space has been cut down by at least 50% and on some instances greater reduction has been achieved."
"Quest QoreStor definitely saved us money."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"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."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"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."
 

Cons

"The solution's pricing could be improved."
"It needs to be more versatile to run our tests smoothly."
"We have had some issues. We are working with HPE to solve all the issues."
"A feature that is missing, compared to the competition, is the ability to globally duplicate all systems."
"Look elsewhere – you can’t change something once you have it, and it accomplishes what it needs to, but it's not leading edge enough to address the new technologies out there."
"One of the drawbacks of this product is that you cannot add another disk array when you reach capacity."
"The initial setup is difficult for the normal user."
"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."
"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."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"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 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."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
 

Pricing and Cost Advice

"The licensing costs is capacity-based and come bundled with support."
"The solution is pretty expensive."
"The price puts me off. It's definitely on the high side."
"The product is not expensive. It is available at a good price."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"The solution's cost is above average."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
