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.

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 is the duplication."

"This is a good solution because it offers multiple hybrid options."

"We are satisfied with Arcserve UDP."

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

"Easy to use, good stability, and disk space gain with greater data protection and we were able to replicate the environment to another place or other platform at no additional cost."

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

"Global deduplication is the best feature of this solution."

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

More Arcserve UDP pros

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"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."

"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."

"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."

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

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

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

"Quest QoreStor definitely saved us money."

More QoreStor pros

Cons

"We used Arcserve as a backup solution, but it wasn't very flexible."

"We have to use a Microsoft hypervisor for installation which is expensive."

"The speed of restores should be improved. We have found the speed of large restores rather slow."

"One of the biggest drawbacks of Arcserve UDP is that it does not have a single console, making it an area that needs to be considered for improvement."

"It takes much time to verify and consolidate images for backups."

"Licensing is an area that needs improvement."

"The solution could improve by being more user-friendly. It can be difficult to assign destinations and choose which files and folders we need to back up. There are some aspects that are unclear."

"The initial setup was complex."

More Arcserve UDP cons

"They need to increase their maximum capacity."

"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."

"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 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."

"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."

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

"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."

More QoreStor cons

Pricing and Cost Advice

"It is approximately $400 to purchase a virtual service outright."

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

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

"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 price is based on the number of sockets. We use a four-socket price that includes two servers and the cost is $4,375."

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

"The licensing cost is for one year. There are not any hidden costs involved in the pricing model of the solution."

More Arcserve UDP pricing and cost advice

"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."

"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."
