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

"HPE StoreOnce has high performance."

"Recovery is important."

"The product’s data retention is very good."

"The product's most valuable feature is stability."

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

"The most valuable feature of HPE StoreOnce is the virtual drive."

"The implementation is straightforward."

"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."

More HPE StoreOnce pros

"Quest QoreStor definitely saved us money."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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 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."

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

"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."

"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."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

More QoreStor pros

Cons

"This product would be improved with the inclusion of more features to security or WORM."

"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 product's price could be better."

"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."

"We do not foresee the need to have an artificial intelligence app. It is not mature enough."

"The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."

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

"The solution must provide backup options for smaller capacities."

More HPE StoreOnce cons

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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."

"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."

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

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"The product's pricing is medium."

"HPE StoreOnce is cheaper compared to other solutions in the market."

"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 solution's cost is above average."

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

"I would rate it around two or three because, compared to others, it tends to be higher priced."

"Price-wise, it comes with a high price tag when compared to other products."

"There are costs for additional storage and space."

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

"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."
