Cost savings and efficient decompression but needs better cloud integration
Our primary use case for Arcserve UDP is its decompression feature, which helped us save money by reducing storage needs. Despite moving to cloud applications, we have been using Arcserve UDP for backup and disaster recovery Arcserve UDP has helped our organization save considerable amounts of…
Jeff Manuszak - PeerSpot reviewer
Cost-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

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 feature of Arcserve UDP is live replication."
"The ease of use is the best feature of the product."
"The ability to switch between different hardware platforms and utilization tools are some of this solution's most valuable features."
"Global deduplication is the best feature of this solution."
"Instant recovery is the most valuable feature of Arcserve UDP."
"The most valuable features are that it is able to restore quickly and that it is able to virtually restore on Hyper-V."
"I like the tool's speed."
"We are satisfied with Arcserve UDP. The most important feature that we use and why we choose this product is the RHA feature."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Quest QoreStor is very stable compared to our previous solution."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"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."
"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."
"Quest QoreStor definitely saved us money."
 

Cons

"Based on my experience, whenever we need support, there are difficulties with communication when trying to resolve the issue."
"We are looking at scaling up to the cloud and using immutable copies on the cloud. Arcserve UDP 8.0 does have the immutable feature supporting AWS, but I'm looking for multi-cloud support. So, I'm waiting for Arcserve to release that in the next release."
"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."
"Licensing can be quite difficult."
"We could not go into granular details of retrieving backup information."
"We cannot restore each user's mailbox. Each user's mailbox should be independently restorable. Also, this solution is very slow. If you select all of the servers, it runs for a long time... It needs to be faster. Finally, If anything happens to one server we should be able to switch to another server."
"The support could be more knowledgeable and faster."
"The solution can improve by allowing older versions to support the latest version of the OS."
"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 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 ransomware protection of QoreStor could use improvement."
"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 need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 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."
 

Pricing and Cost Advice

"I do not work with the pricing or licensing issues of the solution for our organization."
"I rate the product price a five on a scale of one to ten, where one is low price and ten is high price."
"The licensing cost is for one year. There are not any hidden costs involved in the pricing model of the solution."
"The pricing is moderate."
"The solution is expensive."
"The price of StorageCraft ShadowProtect is competitive in the market."
"The solution is not very expensive, but it is not cheap."
"The pricing of the product can be considered to be reasonable enough for the Asian region."
"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."
"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."
