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 technology has been very useful. There are lots of features on offer."
"The most valuable features of PowerProtect DD are the immutable storage and the AI scanning."
"The most valuable features are the deduplication and compression and the Data Domain Boost."
"The most valuable features of PowerProtect DD are the immutable storage and the AI scanning."
"The solution syncs immediately."
"When utilizing Dell PowerProtect DD for backup systems, Data Domain offers fast performance with low latency, providing high throughput for quicker backups compared to other vendors."
"I find the data to be most valuable."
"Its pricing is not overly expensive."
"Quest QoreStor definitely saved us money."
"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."
"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."
"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 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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"I would rate QoreStor a ten out of ten for what it offers for the price."
 

Cons

"We would like to see the price of this solution brought down to be comparable with similar products currently on the market."
"If we lose the admin password, Dell always asks for separate charges."
"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 software from Dell that can be used to operate Data Domain needs to have enhancements made to the user interface. It is too complex."
"The price could be a little cheaper than it is now."
"The model 3330 may need improvement."
"There is an inconsistency in support quality for Dell PowerProtect DD"
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 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."
"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."
"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 ransomware protection of QoreStor could use improvement."
 

Pricing and Cost Advice

"This is one of the more expensive backup solutions on the market."
"There are many options in the pricing structure which can cause some confusion and necessitate the purchase of additional licensing."
"The yearly subscription is very affordable for our customers, but the price could be a little cheaper overall."
"I can't remember what the license costs are. They might be paid monthly or every two months."
"The price of Dell EMC PowerProtect DD could improve, it is expensive."
"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"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."
"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 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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
