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.

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 solution is easy to use."

"The entire system operates seamlessly, with minimal hands-on involvement, allowing us to focus on monitoring rather than constant adjustments or deployments, as seen in larger, more dynamic environments."

"They are extremely reliable and scalable — they provide the best de-duplication on the market."

"The most valuable feature is the integration with Data Domain and your VM stacks."

"The solution scales well."

"The setup is very easy."

"Every product is good and bad, but its claim to fame is that it is scalable; we're doing more than 3,000 VMs, and every single night a complete image backup to disks and replication are easily done in under four hours."

"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."

More Dell Avamar pros

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

"Quest QoreStor is very stable compared to our previous solution."

"Quest QoreStor definitely saved us money."

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

"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."

"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 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."

More QoreStor pros

Cons

"Avamar needs a greater emphasis on storage targets. If it's going to keep pace with the times, it needs more ability to leverage cloud storage."

"The configuration and expansion aspects of the solution need improvement. They're complicated and don't really integrate well."

"When you get down to doing certain things, such as somebody wants a particular file restored, the process by which you do that is stupid. You kind of have to know exactly where to look for in order to find it. Even on older backup products that I've used, I didn't have that kind of problem. If we were looking for a file with a particular kind of a name, the solution would find that file anywhere irrespective of where it resides within the backup system. So, we didn't have to know the name of the specific server, the specific timeframe, almost all the characters of the file name, and all kinds of data in order to find a file. In Avamar, we got to know these details. We've gone around and around with them on that, and their attitude seems to be that it is working just fine. There is nothing for them to improve. The organizational system of other products that I'm working with, such as Zerto and Cohesity, seems to be centered around the tasks that you would most commonly do and want to do, as opposed to we've laid it out in a really neat technical hierarchy."

"The licensing price must be reduced."

"The user interface still needs to have some level of improvement. It could be more user-friendly and intuitive."

"The newest version is not very stable, which is something that should be improved."

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

"The solution could be a bit easier to use in the sense that they need to make it simpler to backup products and restore items."

More Dell Avamar cons

"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 setup of the software is definitely not the easiest thing in the world."

"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."

"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."

"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 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."

More QoreStor cons

Pricing and Cost Advice

"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."

"This solution is less expensive than Veeam for us, although it depends on the customer because we get a great discount."

"It was approximately $70-80,000 when it was under support, but right now EMC has not been supporting this product for two years."

"The cost of the solution is very expensive."

"There is a license required for this solution."

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

"The solution is costly."

"The price is fair."

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."

"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."
