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

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

"Based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line compared to offerings like Data Domain or from Huawei and Lenovo."

"The product has really improved the backup and restore for our infrastructure."

"The most valuable feature would be the high deduplication ratios, capable of 20 or more to 1 dedup ratio in a real-world backup environment."

"The most valuable features for us are the ease of use, the reliability, and the exceptional deduplication that we get across that data that we store on those devices."

"When using de-duplication, backups take less space than they previously did, and this minimizes the costs to our company."

"The product was easy for me in terms of architecture, deployment and support."

"With D2D2T appliance, and backup jobs reconfiguration we are reducing the backup tapes count, as the appliance offers a fast backup and restore process and a data replication mechanism to a remote site location that ensures data center backups disaster recovery."

More HPE StoreOnce pros

"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."

"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."

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

"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 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."

"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."

More QoreStor pros

Cons

"The repository should have an extension to connect to the cloud and deposit the backups."

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

"I'd like it to be quicker."

"The support team needs improvement."

"HPE StoreOnce could improve the capacity support."

"The solution's pricing could be improved."

"StoreOnce doesn’t work for our class of data, which is small, and needs to include more genomic and medical research as test cases."

"The repository should have an extension to connect to the cloud and deposit the backups."

More HPE StoreOnce cons

"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable."

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

"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."

"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."

"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."

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

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."

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

"The product's pricing is medium."

"The solution's cost is above average."

"The licensing costs is capacity-based and come bundled with support."

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

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

"There are costs for additional storage and space."

More HPE StoreOnce pricing and cost advice

"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."

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

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
