Featured Reviews

Andrew Mcbeath - PeerSpot reviewer
Maximized storage capacity and minimized costs and an easy setup
Most of our client base is between fifty to five hundred end users. We occasionally recommend high-end HPE products for larger clients needing performance and reliability. Our clients predominantly use HPE StoreOnce for small business purposes in industries like dairy and finance Our clients have…
Jeff Manuszak - PeerSpot reviewer
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 hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
"The speed and deduplication ratio are two of the most valuable features of the solution."
"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."
"The solution is stable."
"The implementation is not that complex for someone who has experience."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"It's easy to backup data, manage. A"
"Quest QoreStor definitely saved us money."
"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 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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
 

Cons

"We have lost some market due to the minimum capacity now being 80 terabytes."
"The latency is a bit high."
"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."
"The platform's price could be lower."
"The product's price could be better."
"I would like to see an emphasis placed on making data deduplication and compression more powerful."
"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."
"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 ransomware protection of QoreStor could use improvement."
"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."
"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."
 

Pricing and Cost Advice

"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 would rate it around two or three because, compared to others, it tends to be higher priced."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"I rate the platform's pricing a seven out of ten."
"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."
"The product is not expensive. It is available at a good price."
"I rate the product's pricing a seven out of ten."
"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."
"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."
