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

"This is a superior and reliable backup system that can handle large capacities with little management."
"The integration of Dell PowerProtect DD (Data Domain) with leading backup applications within the infrastructure is very good."
"The tool's performance is very good. DD Boost can improve its performance and backup."
"The deduplication feature is the most valuable part of the solution."
"This solution has a feature called Domain Boost, which allows for source deduplication and compression."
"The most valuable features of Dell EMC PowerProtect DD are the duplication security and uptime."
"The most important feature is the level of data compression provided by Dell EMC. It's a leader in data compression and deduplication, and the level of compression isn't available with any other vendors in the market."
"The solution is very stable."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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."
"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."
 

Cons

"We would like to see the price of this solution brought down to be comparable with similar products currently on the market."
"There is a challenge when it comes to data recovery; the recovery window can exceed four to eight hours if you're dealing with backups older than five or ten years."
"The initial setup is complex."
"If I were a manager for this infrastructure, I would look into load balancing for cost, maintenance after sale, and improving Dell PowerProtect DD."
"The price of the product is high."
"They're scalable."
"The firmware upgrades could be simplified. I'm in the process of struggling to upgrade right now."
"The usage of this solution is a bit difficult to develop processes, and it takes a long time to market permits."
"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."
"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."
"The ransomware protection of QoreStor could use improvement."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 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."
"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."
 

Pricing and Cost Advice

"The price of the backup appliance is slightly expensive. Compared to other vendors, the pricing will be slightly higher."
"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"On a scale where one represents high price, and ten represents low price, I rate the solution a five, which means that the solution is of medium pricing."
"In Naira it was twenty-five or twenty-seven million (approximately $75,000 USD) for the implementation and maintenance cost for three years."
"The cost is 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 is expensive, but the performance and deduplication cover for the cost."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"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."
"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."
