AmarpreetSingh - PeerSpot reviewer
Offers improved data protection and security with indirect ROI
The pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions. Currently, Cohesity Cloud seems very costly compared to native backups. Although this is an emerging tool and there is room for growth, it needs to mature further. There is an AI feature, however, it is still in the development phase and requires substantial improvements.
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

"It is easy to install and use."
"The hyper-converged architecture and scalability are hugely important for growing service companies."
"I definitely recommend this tool to others due to its simplicity, security, features, and flexibility."
"I find the most important feature to be data protection."
"We use Cohesity Helios primarily in our data management strategy for backup and reporting."
"Our data center size occupancy for Cohesity appliance is reduced by 70% when we installed Cohesity."
"Its big data and archive data features are the features that I have found most valuable. I can use it in a big virtual environment."
"It's very regimented and fast. It does local backup, cloud backup, long-term coverage, and disaster recovery."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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 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."
 

Cons

"The primary drawback is the need to transfer large amounts of data to the cloud via an internet connection, requiring significant bandwidth."
"Their documentation portal is not up to date for newer releases and I strongly recommend Cohesity to increase their efforts on the documentation portal."
"There is limited support for legacy systems, which is something that could be improved."
"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 pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions."
"The pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions."
"The initial setup can be complex, depending on the environment."
"The limitation that I see in Cohesity is that the minimum sized node is 36 terabytes, which is more than a small customer needs."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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."
 

Pricing and Cost Advice

"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."
"It's priced properly for the market."
"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."
