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.

Pricing and ROI: Dell Avamar is seen as expensive, yet suitable for medium to large enterprises due to its data protection efficiency. QoreStor is capacity-licensed with transparent pricing, offering manageable fees aligning with growth, becoming cost-effective when compared to solutions like Veeam.

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.

Works at a financial services firm with 11-50 employees

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 stability, in general, has been great, with no bugs or glitches, no crashes or freezes, and it is reliable with good performance."

"It's very cost effective and affordable when compared to other solutions."

"We were happy to switch to something else."

"The tool's most valuable features are backup management and speed."

"I have found the product to be scalable."

"The most valuable features are image backups and file backups."

"I like Dell EMC Avamar's compression of data; it's stable and scalable, and I have not had any problems with it."

"The most valuable feature for me is the backup functionality; it gives large enterprises the comfort of knowing their workloads are being backed up."

More Dell Avamar pros

"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."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

"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 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."

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

"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."

"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."

More QoreStor pros

Cons

"What would make Dell Avamar better is if it can do faster backups because right now, PowerProtect Data Manager is better in this area with its new UI and a new way to implement backups."

"The licensing model is not very flexible. Every time we upgrade our storage size, we need to upgrade the Avamar license."

"Performance can sometimes be affected when tools are utilized for tasks like backup or deep archiving."

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

"They should really move to cloud and reduce the price."

"The interface has room for improvement. It's not ideal right now."

"The interface could be more helpful for people."

"The challenges we do face typically revolve around aligning specific features with our accustomed tool usage."

More Dell Avamar cons

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

"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."

"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."

"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."

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

More QoreStor cons

Pricing and Cost Advice

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

"Licensing fees are paid annually."

"The cost is high."

"It is easy to use."

"Dell Avamar, including its virtual add-ons and cloud-based offerings, is cheaper than other solutions, but in the end, the price still depends on your use case. Price-wise, I'm rating Dell Avamar as six out of ten."

"It's an expensive tool"

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

"The solution is expensive."

More Dell Avamar pricing and cost advice

"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."

"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."
