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.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"The performance of Dell EMC Avamar is good."

"Overall, this is a good product."

"The product is very powerful and offers very good performance."

"The installation process is pretty straightforward."

"Graphically, it's very user interactive. It's got a very nice interface."

"The product is good for backups."

"It's stable and offers good performance."

"The tool’s ability to restore files discretely is useful."

More Dell Avamar pros

"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."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

"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."

"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."

"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."

More QoreStor pros

Cons

"There also needs to be single sign-on support."

"Restores should be faster. Backup image browse times should be faster."

"It is integrated with the databases but it's not the best solution for big databases."

"I would like to see better integration with third-party applications and platforms."

"The problems are, that it has issues with support. Dell has issues in that area."

"The performance takes up a lot of resources, unfortunately."

"The UI is not easy to use. There are other products such as Veeam that are easy to use for the end-user which is why they are moving away from Avamar or Networker."

"The client caches and deduplication system have a few problems."

More Dell Avamar cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"The air gap feature is something I'd really like to see in QoreStor."

"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."

"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."

"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 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 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."

More QoreStor cons

Pricing and Cost Advice

"I'm not sure, but perhaps the pricing could be done better at the moment."

"Its licensing is weird. It is not just the licenses; we also purchase hardware. With most software products, such as Veeam, Commvault, and Data Protector, there is no hardware purchase at the same time. Because Avamar and Data Domain are tied together, they have an integrated pipe. You can separate them, but basically, they're designed to work as a couple. Because the Data Domain backend is designed to do dedupe and compression, we get 60:1. When you count it, you count it as a straight compression, but of course, that's with dedupe and some other stuff. You have to buy the hardware, the licensing, and the software at the same time. So, it's not just software."

"Dell's pricing structure is not overly expensive."

"The solution is expensive."

"Dell Avamar is expensive."

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

"It is expensive. The maintenance comes with it for five years. So, you buy the whole thing for five years, and your maintenance is included with it, but it's a big chunk of change upfront. We like capital expenses because we can CapEx them. We pay once every five years, so we spend a big chunk of change. You'd have to divide that out by the five years to come up with how much it costs. It's just about three-quarters of a million dollars for five years."

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

More Dell Avamar pricing and cost advice

"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."

"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."
