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.

Ease of Deployment and Customer Service: Arcserve UDP supports diverse environments, including on-premises and hybrid clouds, though its technical support receives mixed reviews. QoreStor operates mainly in on-premises and private cloud environments, offering faster technical support but requiring more comprehensive services.

Pricing and ROI: Arcserve UDP is about 20% cheaper than some competitors, delivering strong ROI through efficient backup capabilities and reduced server needs. QoreStor's pricing is competitive when scaling with customer needs, with benefits from efficient storage solutions and substantial ROI despite additional costs for third-party software.

Software Solutions Architect at SPEData

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.

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

"Data store deduplication, which saves space on storage and time to backup."

"Just use Arcserve UDP for Backup, Replication, and a High Availability solution; it is one software and one console for all kinds of data protection."

"Arcserve UDP provides security to our database and also it takes backup regularly, without human intervention."

"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."

"It is overall rock-solid."

"Arcserve UDP has a good configuration and user interface. It makes the job of an administrator easy."

"The standard backup and restore feature is most used."

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

More Arcserve UDP pros

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

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

"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."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

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

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

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

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 support could be more knowledgeable and faster."

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

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

"Taking a snapshot level backup with this solution is very slow compared to other products."

"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."

"Its interface can be improved. I find it unintuitive."

More Arcserve UDP cons

"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."

"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."

"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 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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

More QoreStor cons

Pricing and Cost Advice

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

"The solution is expensive."

"The price of StorageCraft ShadowProtect is competitive in the market."

"Its price seems reasonable. Its price is average as compared to the other products I've looked at. We have a three-year license right now. There are no other costs beyond the standard licensing fee."

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

"The solution is very expensive."

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

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

More Arcserve UDP 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."
