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.

Cost savings and efficient data management improve operations but support quality varies

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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."

"It results in more efficient storage utilization, cutting capital expenditure in half."

"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."

"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."

"The implementation is straightforward."

"It's easy to backup data, manage. A"

"The implementation is not that complex for someone who has experience."

"From a centralized system, I can manage the interface, the backup policies, and the status of the database."

More HPE StoreOnce pros

"Quest QoreStor is very stable compared to our previous solution."

"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."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"Quest QoreStor definitely saved us money."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

More QoreStor pros

Cons

"The solution could always be less expensive."

"The latency is a bit high."

"The web interface, ease of use, and GUI all need to be improved."

"The product could be improved with better support for data protection."

"The setup phase is not so simple that an end user can plug and play to make it operational."

"Its customer service could be faster."

"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."

"The user interface of HPE StoreOnce is an area of concern where improvements are required."

More HPE StoreOnce cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"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."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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."

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"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."

"I rate the platform's pricing a seven out of ten."

"The product is not expensive. It is available at a good price."

"I rate the product's pricing a seven out of ten."

"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."

"The price puts me off. It's definitely on the high side."

More HPE StoreOnce pricing and cost advice

"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."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
