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

"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."
"The hyper-converged architecture and scalability are hugely important for growing service companies."
"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."
"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."
"It's very regimented and fast. It does local backup, cloud backup, long-term coverage, and disaster recovery."
"We use Cohesity Helios primarily in our data management strategy for backup and reporting."
"It is easy to install and use."
"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 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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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 is very stable compared to our previous solution."
 

Cons

"The initial setup can be complex, depending on the environment."
"The primary drawback is the need to transfer large amounts of data to the cloud via an internet connection, requiring significant bandwidth."
"In terms of functionality, Helios has been effective, but sometimes it doesn't show the exact cluster name for backups."
"Their documentation portal is not up to date for newer releases and I strongly recommend Cohesity to increase their efforts on the documentation portal."
"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 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."
"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."
"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."
"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."
"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."
"The ransomware protection of QoreStor could use improvement."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
 

Pricing and Cost Advice

"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."
"Regarding pricing, it's very costly and I rate it a four."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"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."
