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 product, a disk backup solution, improves our data application tasks. We used tape libraries with Dev drives in legacy architectures, resulting in slow backups compared to modern drives like NVMe and SSDs. By transitioning to NVMe and SSDs, backups have become much faster. The tool's backup restoration is faster compared to other tools."
"The most valuable features of PowerProtect DD are the immutable storage and the AI scanning."
"The licensing model is the most valuable aspect of Dell PowerProtect DD"
"Good starting capacity and scalability."
"We have never had any issues with Data Domain. It has been stable."
"Most cases are related to databases, such as Oracle and MySQL."
"The most valuable features are the deduplication and compression and the Data Domain Boost."
"The most valuable feature is the performance because you can back up data really quickly."
"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."
"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."
"Quest QoreStor definitely saved us money."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
 

Cons

"Dell PowerProtect DD does not have integration with the cloud and virtualization software."
"EMC is very expensive for small customers."
"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 Dell PowerProtect DD architecture offers several significant features. One is DD Boost, which is utilized at both the source and destination sites for application processing."
"If we lose the admin password, Dell always asks for separate charges."
"The model 3330 may need improvement."
"The software from Dell that can be used to operate Data Domain needs to have enhancements made to the user interface. It is too complex."
"We have had deduplication and replication issues. When we used another backup software we noticed that it didn't have the same issues."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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 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."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
 

Pricing and Cost Advice

"We usually buy products at the end year, and the license is included."
"Users have to pay a capacity-based licensing fee for the solution."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"It is expensive, but the performance and deduplication cover for the cost."
"The pricing is cost-effective for the solution"
"Becoming more expensive."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"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 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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
