Support and connection issues affect user experience

I currently work at TCS in a different domain using AWS and Azure cloud backup. I switched from Cognizant to TCS four months ago, where I previously used Cohesity Data Cloud and Cohesity tools. I prefer Cohesity Data Cloud over AWS. While cloud functionality is similar across platforms, Cohesity Data Cloud's console, options, and web console are superior to AWS. The pricing of Cohesity Data Cloud depends on the data volume and retention period. Compared to alternatives, Cohesity Data Cloud is somewhat expensive. Regarding technical aspects, connection issues need to be addressed promptly. I would rate it eight out of ten, as these issues require immediate resolution to meet client requirements. Overall review rating: 9/10.

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

"Cohesity Data Cloud comes with a different flavor where they provide global deduplication across multiple platforms, which provides a tremendous return on investment from a storage perspective because if you have a segment that can be deduplicated in one box and you have multiple boxes, you cannot repeat the deduplication function across different hardware."

"Cohesity Data Cloud is user-friendly, and anyone can use this tool; the support is really good, especially the web support, and the dashboard and everything are good."

"I rate the Cohesity Data Cloud solution a ten out of ten. It's an easy-to-use product that provides substantial value and security."

"Our data center size occupancy for Cohesity appliance is reduced by 70% when we installed Cohesity."

"We use Cohesity Helios primarily in our data management strategy for backup and reporting."

"My favorite feature of Cohesity Data Cloud is the setup, as it is very fast compared to other solutions; I have worked in different clouds, and Cohesity Data Cloud stands out as superior."

"The clone feature is very nice. You can restore workloads onto Cohesity's storage, which is also nice to have when you don't have enough space to restore on the server."

"The hyper-converged architecture and scalability are hugely important for growing service companies."

More Cohesity Data Cloud pros

"Quest QoreStor is very stable compared to our previous solution."

"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 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."

"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."

"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."

"Quest QoreStor definitely saved us money."

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

More QoreStor pros

Cons

"Sometimes the support team does not provide proper assistance during critical issues from the cloud end."

"There is limited support for legacy systems, which is something that could be improved."

"The pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions."

"Sometimes the support team does not provide proper assistance during critical issues from the cloud end."

"In terms of functionality, Helios has been effective, but sometimes it doesn't show the exact cluster name for backups."

"The pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions."

"It has never been touted as a tier-one storage platform, and that would be a benefit. They are currently working on solving that issue."

"The only concern I have with cloud implementation is that if you have a presence on-premises, trying to use the cloud may become a performance challenge."

More Cohesity Data Cloud cons

"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."

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

"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 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."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

More QoreStor cons

Pricing and Cost Advice

"It's priced properly for the market."

"Regarding pricing, it's very costly and I rate it a four."

"Competing products sometimes use deceptive marketing to make their products seem a lot cheaper. Comparing apples-to-apples, DataPlatform wins out."

"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 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."

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