Giovanni Golinelli.

Hybrid IT Architect at Quanture Spa

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

CTO at EDSI

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

"I love the ability to clone a virtual server in only minutes."

"The spin-up of a VM within a test environment for backup testing along with quick restores."

"The system automatically takes down the nodes one at a time and performs the upgrade and brings the node back up before proceeding to the next. Upgrades can now be done at any time with a high level of confidence."

"Setup was extremely easy from racking to backing up was about one hour."

"The solution is stable, with regular updates and patching."

"After linking a cloud subscription, like Azure for example (AWS and Google are also supported), you can "spin" a VM onto the cloud from any backup snapshot."

"It has a lightning fast restore."

"The most valuable feature is ease of use."

More Cohesity DataProtect pros

"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."

"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."

"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."

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

"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."

"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."

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

More QoreStor pros

Cons

"In terms of what could be improved, it just needs some maturity."

"The one area where we would like to see additional improvements is with reporting. There are very granular reports from each grid. There are also some built-in reports within Helios (SAS Management Console) that offers basic reporting. However, for complex, large-enterprise environments, a more robust reporting engine that supports detailed audit reporting and enhanced ad hoc reports would be welcome."

"The support team could do a better job. Sometimes finding the correct person is cumbersome and time consuming."

"Cohesity DataProtect can improve in the area of databases. We have had some challenges with both Cohesity and Rubrik being able to effectively back up in a timely manner the SQL Oracle workloads."

"Cohesity DataProtect needs to improve its reporting capabilities."

"I'd like to be able to pause a backup while it's running and have it resume when I tell it to resume."

"This solution is only compatible with a limited number of storage arrays, including Pure and Cisco Hyperflex."

"What areas have room for improvement? Is there anything that could be simplified to make it better?"

More Cohesity DataProtect cons

"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."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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."

"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."

"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."

"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 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."

More QoreStor cons

Pricing and Cost Advice

"Pricing, setup costs, etc. are pretty typical. The initial cost for Cohesity was less than other products the we evaluated. Cohesity's pricing does offer benefits as DR target costs are less than other solutions. You are not charged for DataProtect licensing for target DR data consumption."

"Cohesity came in at the best price."

"The solution's pricing is quite high, more so than that of its competitors, Veeam, Veritas and Rubrik."

"It has reasonable pricing, and we know they can give discounts. If you look at the primary pricing or the list pricing, it conforms to the market pricing, but you have to have a discount on it. Otherwise, it is way too expensive."

"Ensure that you understand the per TB licensing model. Also, Exchange backups are not native to Cohesity and require Kroll."

"From my last assessment, the pricing for Cohesity DataProtect was reasonable. Compared to its closest competitor, Rubrik, I found Rubrik's pricing to be somewhat high-end. While Rubrik may have more advanced security features than Cohesity DataProtect currently, Cohesity DataProtect is releasing a new solution in the near future that will compete directly with Rubrik."

"With respect to pricing, make sure that you look at both Rubrik and Cohesity as they are very similar and are quite competitive."

"Cohesity came in at the best price. Setup was included and done in half a day."

More Cohesity DataProtect pricing and cost advice

"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."

"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."
