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

"The stability is excellent."
"I like Data Domain as a protocol for data backup."
"Dell is more stable than any other device."
"The most valuable features of this product are its guaranteed reliability and its duplication capability."
"The solution is very stable."
"The hardware can operate in high temperatures, in case of any disaster."
"Its pricing is not overly expensive."
"PowerProtect is a flexible solution that you can cover various cloud and on-premise environments."
"Quest QoreStor definitely saved us money."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"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."
 

Cons

"Dell PowerProtect DD should come out with its own system so we do not have to use Data Domain. For example, something similar to what Symantec has done."
"The pricing model needs to be improved."
"When you use Data Domain, you have to have at least 20% free space so it can work properly. Sometimes we struggle with that, because we wanted to use all the free space, but then Data Domain becomes really slow. I understand that 20% is needed to process all the data, and doing the duplication and compression and all that, but it would be a big improvement if they did not require that 20%, because it is just too much to have available."
"We have some problems with backing up on the Power Platform. PowerServer is an IBM product, and it forces us to back up over LAN, which is not suitable for us."
"They should reduce the CPC cost to customers. The product is becoming very expensive."
"DD Boost."
"We are not able to deal directly with the OEM we have to go to their partners in Nigeria."
"Dell PowerProtect DD (Data Domain) is expensive. Also, it has a sort of a big physical footprint that data domains have, and that's part of the problem."
"The ransomware protection of QoreStor could use improvement."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"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. Other than that, they're doing a pretty good job."
"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."
"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."
 

Pricing and Cost Advice

"I can't remember what the license costs are. They might be paid monthly or every two months."
"This is one of the more expensive backup solutions on the market."
"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."
"Pricing is related to size. A lower range solution might be about $33,000. My customers use higher range versions with a price of around $100,000. That's the price for both the hardware and software."
"Becoming more expensive."
"The price may be a bit higher than other products in the market, but you will receive ten out of ten support with next-business-day delivery on parts' availability."
"It could be more competitively priced. Its licensing was for five years. Obviously, the support will get renewed at some stage, but that's it."
"The yearly subscription is very affordable for our customers, but the price could be a little cheaper overall."
"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."
"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."
