Executive SummaryUpdated on Nov 23, 2025

Arcserve UDP and QoreStor are leading data protection solutions. QoreStor seems to have the upper hand due to its advanced deduplication and scalability, which are important for data efficiency and storage cost reduction.

Features: Arcserve UDP supports physical systems and offers agentless backup for VMware and Hyper-V, as well as global deduplication. It is praised for remote replication, virtual standby, and cloud integration, in addition to handling Windows and Linux systems. QoreStor stands out with powerful data deduplication and compression, significantly reducing storage costs. It is designed for low maintenance, offers cloud tiering, and supports various backup software solutions.

Room for Improvement: Arcserve UDP users desire better integration with physical hardware and cloud environments, as well as improvements in support services and licensing complexity. Users report issues with high RAM usage and slow restoration speeds. QoreStor users highlight a cumbersome installation process and seek improvements in ransomware protection and support automation, including faster support responses.

Ease of Deployment and Customer Service: Arcserve UDP is often deployed on-premises and in hybrid cloud environments, benefiting from a straightforward setup. Although technical support is generally decent, response times can be slow. QoreStor is also deployed on-premises, with user experiences of technical support ranging from excellent to needing improvement, particularly in automation and user guidance.

Pricing and ROI: Arcserve UDP's pricing is seen as moderate, with some labeling it costly but justified by its features, contributing to significant ROI. Arcserve's annual licensing is cost-effective compared to competitors like Veeam. QoreStor's capacity-based pricing is flexible and scalable, praised for allowing easy license adjustments as data needs evolve. It offers strong ROI through efficient storage usage and reduced licensing costs.

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 recovery part of the product is very good."

"It is a very stable solution...It is a scalable solution."

"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."

"It allows us to back up all the servers and centrally manage them."

"This product is extremely user-friendly and it is capable of performing large-scale archive/backup (five+ years worth). It is easy to store, maintain, and check backups."

"Our customers are happy with the product’s functionality."

"The most valuable feature of StorageCraft ShadowProtect is the speed and the compression of the backups. The compressed backed-up files do not take up as much storage. Additionally, the incremental backups can be done in one minute and be backed up on a disc very fast."

"The ability to switch between different hardware platforms and utilization tools are some of this solution's most valuable features."

More Arcserve UDP pros

"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."

"Quest QoreStor definitely saved us money."

"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."

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

"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."

"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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

More QoreStor pros

Cons

"Arcserve UDP is in the middle range of complexity. The interface can be developed a little bit more to be user-friendly."

"The only problem with the solution is that when I change the drive capacity, it has to do a full backup. It's a problem when I have five servers to backup. When I only want to change the size of the drive, I have to do a full backup that can take one week."

"The initial setup was complex."

"The tool doesn't provide cloud integration in India."

"Licensing is an area that needs improvement."

"The technical support of the product is an area of concern where improvements are required."

"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."

More Arcserve UDP cons

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

"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."

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

"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."

"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

"The pricing of the product can be considered to be reasonable enough for the Asian region."

"In comparison to other vendors, it is a low-cost solution."

"I feel that the product is fairly priced."

"Pricing is most likely comparable."

"The solution is not very expensive, but it is not cheap."

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

"The solution is expensive."

"There are annual subscription fees and there are licensing costs for three computers. It is an expensive solution."

More Arcserve UDP 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."

"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."

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