Executive SummaryUpdated on Mar 1, 2026

Dell Avamar and QoreStor compete in the backup and recovery solutions market. Avamar has the upper hand due to its integration with Data Domain, enhancing compression ratios and scalability, while QoreStor stands out for its flexibility and hardware independence.

Features: Dell Avamar includes client-side deduplication and almost instant access restores, offering comprehensive backup capabilities across various platforms. Its integration with Data Domain improves compression and scalability. QoreStor offers strong deduplication and replication, running on different hardware types, and is versatile across multiple backup workflows.

Room for Improvement: Dell Avamar could enhance its troubleshooting features and cloud integration, particularly for SQL backups. The discontinuation of its hardware version raises concerns among users preferring physical solutions. QoreStor needs better ransomware protection and support capability, along with improved UI and replication across cloud environments.

Ease of Deployment and Customer Service: Dell Avamar is typically deployed in on-premises and hybrid cloud environments but receives mixed reviews about its customer service. QoreStor is mainly on-premises, appreciated for ease of installation and adaptability, though it shares similar support challenges.

Have supported critical environments despite room for improvement in legacy backup options

It is very efficient in cyber resilience. Deduplication, automation, and everything is very efficient. It is multi-cloud enabled and has broad protections. The software delivers flexible and efficient backup and recovery options through its cyber resiliency features. Dell PowerProtect Manager provides insights in managing backup processes. Its encryption mechanisms are very efficient, helping to secure sensitive data. Its integration with Dell EMC Data Domain is very good. It is easy to integrate with Data Domain. Multi-cloud options are enabled, and backup in cloud options exist in Dell Avamar.

Cost savings and efficient data management improve operations but support quality varies

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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Avamar's source side deduplication is very strong, it can easily back up remote sites' data, and not much bandwidth is required on the Avamar side."

"The product has a proven track record of good backups without much of a failure ratio. It also has a good backup in terms of the compression ratio."

"The installation of the solution is easy."

"Duplication and the speed of backup are great."

"Scheduling is valuable. It does a good job of backing up, and it does a good job of restoring. Nobody has got a problem with that. The agents are well supported."

"The source site replication feature is valuable."

"It is a very complete product."

"Source based deduplication is the most attractive feature as it drastically reduces the backup window."

More Dell Avamar pros

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"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."

"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."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"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 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."

"Quest QoreStor definitely saved us money."

More QoreStor pros

Cons

"The product could be improved by simplifying the components available."

"There are instances where backups fail on certain applications, which is an area that could be improved."

"The recovery is a bit slow."

"The licensing price must be reduced."

"It lacks support for certain plugins, like SAP HANA, for example."

"The user interface needs to be improved. It's not as good as it could be."

"It's very slow to backup and store information. It has two consoles and an application which are more difficult to use than a solution like Veeam."

"The support is very bad."

More Dell Avamar cons

"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 ransomware protection of QoreStor could use improvement."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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."

More QoreStor cons

Pricing and Cost Advice

"It was very expensive before, but after integrating it with Dell EMC Avamar Data Protection suite licensing, we are getting better discounts."

"There are licensing costs for Dell EMC Avamar and it is paid annually."

"This is a fairly expensive solution. It cost approximately 21,000 each year."

"It is expensive. Its cost is the main thing."

"When it comes to competition the price is not what is important, it's not the problem."

"Dell Avamar is expensive."

"Dell EMC needs to lower Avamar's price and add more features to stay competitive."

"The solution is not expensive for the value one gets."

More Dell Avamar pricing and cost advice

"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."

"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."
