Backup operations have become faster and daily recoveries run smoothly for on‑prem workloads

When compared to other tools, the deduplication in Cohesity DataProtect is very fast, and the restore performance is better than other tools. Global deduplication ensures that only unique data blocks are stored, significantly reducing storage consumption. Cohesity DataProtect's dashboard displays options and errors clearly, making it easy to access and understand how to fix issues. Cohesity DataProtect's ability to start processes automatically without manual selections enhances its reliability. Cohesity DataProtect's architecture ensures that agent installations automatically reflect in the dashboard, allowing for seamless integration into backup jobs. This improves operational efficiency, ensuring backups can be triggered without manual refreshes. Additionally, the user interface is intuitive, and the respect of the N-1 rule during updates helps prevent client-affecting issues.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The implementation and training are all done through the sales engineer, which provides for a seamless and great experience when it comes to starting with a new vendor."

"How do you use Cohesity DataProtect to streamline data backup and recovery in your organization? How do you and your clients use AI to improve data?"

"Integration with AWS has been invaluable to us."

"Cohesity is extremely easy to use and intuitive."

"Compared to the products that we had earlier, Cohesity replaced our primary backup solution, runs VMs, and hosts all our backup mount points in our environment at a fraction of the cost."

"The solution is stable."

"The support is awesome. They are very fast, competent and friendly."

"Reliable backup solution with many options and friendly/logical backup/restore infrastructure."

More Cohesity DataProtect pros

"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."

"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."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

"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."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"Quest QoreStor definitely saved us money."

"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."

More QoreStor pros

Cons

"We found scaling Cohesity to be very challenging."

"We are waiting on the AIX agent to be released."

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

"If someone were to change an admin account password, I would like an alert raised for that, which is not available at the moment."

"Since it is an evolving product, there are lot of frequent releases which require upgrades to be done every other weekend."

"There is room for improvement in terms of price."

"Their documentation could be refined."

"The product is still young and is continually improving. There have been a couple of buggy releases in the software that have caused us minor issues, so possibly some better QA before releasing would prove to be useful. We have also been inquiring about new app and functionality via the Marketplace that was teased months back but has yet to come to fruition."

More Cohesity DataProtect cons

"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."

"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."

"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 in the world."

"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."

"The air gap feature is something I'd really like to see in QoreStor."

"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."

More QoreStor cons

Pricing and Cost Advice

"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."

"If SQL is in heavy use at your location, I would highly recommend narrowing your PoC testing to Cohesity and Rubrik. They will be competitive on pricing with each other, so really put them through the paces."

"The solution's pricing is in the mid-range, where it's neither costly nor cheap."

"We purchased support from Cohesity to ensure that should we face an issue, we don't have to deal with different service providers."

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

"My advice is to always negotiate for better pricing."

"The tool's pricing is average."

"The tool's licensing costs are yearly. It is cheaper than other backup solutions."

More Cohesity DataProtect pricing and cost advice

"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."

"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."
