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 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 most valuable features are the deduplication and compression and the Data Domain Boost."
"The tool's performance is very good. DD Boost can improve its performance and backup."
"I like Data Domain as a protocol for data backup."
"The most valuable features of Dell EMC PowerProtect DD are the duplication security and uptime."
"Our clients like the wide range of features that are available within this single solution."
"Stable and scalable suite of solutions with deduplication, apart from data protection, storage, and backup."
"The backup is very secure. The deduplication using EMC is very good. We are able to make systems and handle random cloning. EMC is a very stable solution for making backups."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
 

Cons

"The price could be a little cheaper than it is now."
"The pricing could be better, but it's still not too expensive."
"Dell PowerProtect DD could improve by having better integration with other backup solutions."
"If we lose the admin password, Dell always asks for separate charges."
"The initial setup is complex."
"The tool's pricing could be cheaper."
"It can probably have integration with other OEMs. It should also have more features for ransomware protection."
"The only problem is that it's more expensive than any other vendors available in the market."
"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."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 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

"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 cost-effective for the solution"
"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."
"The product is expensive."
"It is expensive, but the performance and deduplication cover for the cost."
"The price of the backup appliance is slightly expensive. Compared to other vendors, the pricing will be slightly higher."
"The approximate license cost for Dell PowerProtect DD (Data Domain) is around 5,00,000."
"The cost is expensive."
"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 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."
