Featured Reviews

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

"Cohesity DataProtect is easily manageable, and you can see every option from the user interface."

"This solution is easy to manage."

"Cohesity DataProtect is user-friendly and straightforward. The setup process was effortless, and both the backup and restore operations are speedy."

"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."

"Instant volume mount and the SpanFS filesystem itself, which has great dedupe and compression across all of our backups."

"We can run test scripts on production data."

"It works well with backup virtual machines and SQL services we have been using."

"We are looking forward to the next release, so we can take advantage of the AHV backup for our Nutanix environment."

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."

"Quest QoreStor definitely saved us money."

"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."

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"Quest QoreStor is very stable compared to our previous solution."

"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."

More Quest QoreStor pros

Cons

"Reporting is one area that isn't as robust as it could be."

"Physical RDMs on virtual machines could be a bit easier to configure and plan out."

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

"I think Cohesity could add more platform support. For example, they could improve integration with DB2 or make the integration S3 object storage a little tighter. Some of that stuff could use some work, but overall, it's a relatively comprehensive platform."

"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."

"Many of the reports are basic, at most, and at times we had to open a support ticket to help find or develop a report for our needs."

"Add the ability to delete View Boxes and External Targets in the GUI."

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

More Cohesity DataProtect cons

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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 ransomware protection of QoreStor could use improvement."

"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 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 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."

More Quest QoreStor cons

Pricing and Cost Advice

"Licensing is per node and per protected terabyte. You will also pay 10-15% annually for support."

"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."

"Cohesity came in at the best price."

"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."

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

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

"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."

"The pricing model is impressive and very effective."

More Cohesity DataProtect pricing and cost advice

"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."

"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."
