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-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"The new solution is safe, efficient and cost effective."
"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."
"I recommend this product because of the easy integration with Veeam and other backup products."
"We have saved time as less is spent on tape handling, and there are fewer hardware issues than with a tape."
"For anybody looking for a robust backup solution that emulates a tape library, this is the product that they should go for."
"HPE StoreOnce is an easy-to-use tool."
"Quick recovery."
"If you want a reliable and reasonably-priced product, I would recommend it."
"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."
"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."
"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."
"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."
"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."
"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."
"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."
 

Cons

"I think that technical support is a weak point. I feel that technical support does not know the product."
"We selected this as a method to improve and better scale our backup deduplication, but it turned out StoreOnce introduced enough inconsistencies and incompatibilities, we actually went back to Commvault’s native deduplication."
"I'd like to see the cloud integration simplified."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"HPE technical support is a bit slower compared to EMC, which might have a larger support team that can respond faster."
"I would like to see better integration with Veeam software."
"We had one problem when data replication got stuck and we had to ask HP for help."
"The one issue I have is the maintenance package – it's very expensive."
"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."
"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."
"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 in the world."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"They need to increase their maximum capacity."
 

Pricing and Cost Advice

"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 licensing costs is capacity-based and come bundled with support."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"The product is not expensive. It is available at a good price."
"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 rate the platform's pricing a seven out of ten."
"The cost of HPE StoreOnce is very expensive."
"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."
