Executive SummaryUpdated on Mar 1, 2026

Arcserve UDP and QoreStor compete in the data protection and backup solutions category. Arcserve UDP seems to have the upper hand due to its cost-effectiveness and broader deployment support.

Features: Arcserve UDP's key features include its decompression capability, enabling efficient use of server storage, agentless backup for VMware and Hyper-V, and global deduplication for better data management. QoreStor focuses on data deduplication and compression, offering integration with various backup software and hardware-independent deployment for flexibility.

Room for Improvement: Arcserve UDP could improve its console integration for better cloud interaction, address speed issues during backups, and simplify the licensing process. QoreStor needs to enhance its management interface, improve support responsiveness, and strengthen its Linux-based ransomware protection.

Has supported hybrid IT environments effectively and offers strong data protection

With Arcserve UDP, the most valuable feature is to improve persistent data, which I consider important. I use other products too, not only Arcserve UDP, as we use TrueNAS as well. Arcserve UDP improves the precision of data. I have utilized Arcserve UDP's data deduplication feature, and the data deduplication feature helps my storage efficiency significantly. I have used Arcserve UDP's continuous data protection. It is beneficial for operational continuity because we use it constantly and have no objections to Arcserve UDP technology; I think it is very good. Arcserve UDP's integration with multiple operating systems is very good and very efficient. This brings value for me since many of my clients have different operating systems like Windows and Linux; there is no problem. Regarding the deduplication and compression with Arcserve UDP, I think Arcserve UDP is still a solid solution that we primarily use.

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

"The most valuable features are that it is able to restore quickly and that it is able to virtually restore on Hyper-V."

"The product provides instant and virtual standbys."

"The most valuable feature of Arcserve UDP is the initiative UI and the logs are clear and detailed that are generated when there has been an issue or failure on the user's system. We only have to log onto the client's system to retrieve the information. It is possible to precisely identify the problem's location. The system categorizes and logs every step in a structured manner, selectively displaying only the essential logs. However, to view a comprehensive log, one must access the line machine log and examine the actual client for detailed logging."

"The interface is very refined, works fine, and is very intuitive most of the time. Scalability is nice. The multi-tenancy feature is very welcome. The integration with Linux works fine too."

"Their technical support is excellent."

"Arcserve UDP's integration with multiple operating systems is very good and very efficient, which brings value for me since many of my clients have different operating systems like Windows and Linux; there is no problem."

"I proposed and set up DR and HA solutions for customers who are high profile and in need of business critical functionalities."

"The most valuable features are the replication to the cloud and the deduplication."

More Arcserve UDP pros

"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."

"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."

"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."

"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."

"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."

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

More QoreStor pros

Cons

"It should be easier to switch between backup locations. We have multiple data storage locations and sometimes one of those storages need to be replaced."

"I had an issue with Arcserve UDP during the failover and the secondary machine didn't get back online, even though it ran automatically. I faced the issue during a crisis situation. However, I haven't faced such a problem again."

"The solution's reporting could be improved and should provide customized reports."

"They could work on their marketing approach. I don't see many people leveraging it."

"A lot of their new technologies are not very good."

"We could not go into granular details of retrieving backup information."

"It should be easier to switch between backup locations. We have multiple data storage locations and sometimes one of those storages need to be replaced. It would be nice if they made it easier to reconfigure the backup configuration."

"The reason for this is that the support network for Arcserve appliances is not available in most of the countries outside USA or EU to replace broken units in less than 15 days."

More Arcserve UDP 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."

"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."

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

"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 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."

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

More QoreStor cons

Pricing and Cost Advice

"As an MSP partner, I believe that the prices are fair."

"It is a bit pricey, considering the reliability problems. If the tool worked flawlessly, the price would be fair, even cheap."

"The price of this product is high and it should be lower."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a four or five out of ten."

"The solution is priced well compared to other solutions."

"I do not work with the pricing or licensing issues of the solution for our organization."

"The solution is very expensive."

"I rate the product price a five on a scale of one to ten, where one is low price and ten is high price."

More Arcserve UDP pricing and cost advice

"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."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
