Featured Reviews

Faisal_Zia - PeerSpot reviewer
Offers efficient data management with robust features and reliable performance
Dell PowerProtect DD (Data Domain) can be improved in terms of price. While Dell is providing a proper device, other solutions, such as Symantec, can replicate their data through any NAS storage. Although their deduplication and compression might not be as effective, they can still accomplish the task. Medium-level and SME-level businesses can easily utilize this feature, but Dell PowerProtect DD (Data Domain) is a relatively expensive solution to propose to customers.
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

"PowerProtect is a flexible solution that you can cover various cloud and on-premise environments."
"It is stable. I would rate the stability of the solution a nine out of ten."
"The initial setup was straightforward. Deployment takes about two weeks."
"Short backup window has made a difference in the way my organization functions."
"The most valuable feature is the performance because you can back up data really quickly."
"The deduplication feature is the most valuable part of the solution."
"The most valuable features of this product are its guaranteed reliability and its duplication capability."
"The solution can scale up to one petabyte right now. It's very good for enterprise-level organizations."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
 

Cons

"It can probably have integration with other OEMs. It should also have more features for ransomware protection."
"I would like to see better integration and support for backing up to cloud providers such as Alibaba Cloud."
"The licensing model was the biggest concern for our company, but the poor support after the initial implementation is of equal concern."
"The only problem is that it's more expensive than any other vendors available in the market."
"The solution's cost, scalability, and licensing model could be improved."
"The firmware upgrades could be simplified. I'm in the process of struggling to upgrade right now."
"Looking at Dell PowerProtect DD (Data Domain), there is a need for improvement, especially in terms of protection from cyber resiliency, cyber recovery, or man-in-the-middle attacks."
"Dell PowerProtect DD could improve by having better integration with other backup solutions."
"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."
"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."
"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."
"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 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 cost is expensive."
"The price is on the high side."
"The product is expensive."
"The pricing is cost-effective for the solution"
"The solution is expensive. However, if you pay less you receive less, it is cost-effective."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"The price is really high compared to other vendors. The licensing cost is huge. Normal, mid-tier companies or small-scale companies wouldn't be able to afford it easily."
"The price of the backup appliance is slightly expensive. Compared to other vendors, the pricing will be slightly higher."
"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."
