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

"We also really benefit from the GUI capabilities."
"The product has really improved the backup and restore for our infrastructure."
"We have saved time as less is spent on tape handling, and there are fewer hardware issues than with a tape."
"StoreOnce gives us full-system backups, meaning we need less storage capacity, which is very important to us because less storage capacity means we buy less hardware and have less overall costs."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
"Backups are much quicker now; previously, it took 15-16 hours every day, and now it takes 3-4 hours maximum."
"Support is the main thing; if we have any issue, it’s easy for us to track or investigate it, because we don’t have different solutions from different vendors."
"Its catalyst store and deduplication are valuable as it saves disc space."
"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."
"Quest QoreStor definitely saved us money."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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."
"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."
"Quest QoreStor is very stable compared to our previous solution."
 

Cons

"The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better."
"Scalability can become an issue once you grow past the capacity of a single cluster pair."
"So when we had the systems put in the technician that came out actually hadn’t seem them before."
"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."
"An improvement would be an improved deduplication algorithm."
"The support team needs improvement."
"We are looking for Federated VTLs just like Federated Catalyst Store. Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."
"In the beginning, we had a lot of problems with bad firmware."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The ransomware protection of QoreStor could use improvement."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The setup of the software is definitely not the easiest thing in the world."
"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."
 

Pricing and Cost Advice

"The solution's cost is above average."
"The price of the product is reasonable."
"Price-wise, it comes with a high price tag when compared to other products."
"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."
"There are costs for additional storage and space."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The solution is pretty expensive."
"The price puts me off. It's definitely on the high side."
"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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
