Featured Reviews

Giovanni Golinelli. - PeerSpot reviewer
Easy to use, offers good scalability and responsive support
The deployment depends on the environment. Deploying on VMs is relatively simple. But for most of our customers, we implement physical clusters with at least three configured hosts using the existing model. So, it depends on the setup. Implementing DataProtect itself wasn't particularly challenging. One key requirement for successful DataProtect deployment is proper network configuration. If the network setup isn't right, you won't achieve optimal performance. We have developed a service for some of our customers where they implement an appliance or physical cluster of Cohesity at the customer site. Then, we use cloud clustering to replicate, and even in production, a second copy of the protected data. And in some cases, we have developed some disaster recovery procedures using Cohesity.
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's completely reliable and easy to restore."
"The four independent node cluster architecture is redundant. It maintains data integrity and load balancing."
"Setup was extremely easy from racking to backing up was about one hour."
"The product is easy to put in place. All backups are done very quickly. It's easy to perform restores. What I prefer in the product is its simplicity. There are no useless settings to define, and everything is ready after the initial setup."
"The most valuable features are the rapid VM restores and the ability to quickly find files and download them directly to my desktop so that I can put them where I need them to be."
"I love the ability to clone a virtual server in only minutes."
"It works well with backup virtual machines and SQL services we have been using."
"Cohesity DataProtect is more of a unified solution, which is also trying to expand for ransomware protection."
"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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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 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."
 

Cons

"I would like to see Cohesity have the ability to do a file level restore from a Windows server, which is storing data on dynamic disk."
"Cohesity cluster upgrades have not been as easy as a single button click. They are a manual process that requires upgrading each node into a cluster individually."
"In terms of the product itself, there have been a handful of patches that have had to be applied outside of the GUI via the command line. It's very straightforward and easy and in the same redundant fashion, but not quite as simple as one or two clicks. I'm hoping that will decrease going forward."
"Non-cloud services need improvement."
"The solution has a more complex setup than Veritas and Veeam."
"Cohesity DataProtect needs to improve its reporting capabilities."
"If someone were to change an admin account password, I would like an alert raised for that, which is not available at the moment."
"This solution is only compatible with a limited number of storage arrays, including Pure and Cisco Hyperflex."
"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."
"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."
"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 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."
"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."
"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."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly. It is cheaper than other backup solutions."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."
"I expect the system to probably pay off within the first two years."
"The solution's pricing is quite high, more so than that of its competitors, Veeam, Veritas and Rubrik."
"The tool's pricing is average."
"Sizing is important and it is easy to overestimate."
"Ensure that you understand the per TB licensing model. Also, Exchange backups are not native to Cohesity and require Kroll."
"The pricing model is impressive and very effective."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
