Specialist at HCLSoftware

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.

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

"We are happy with the support provided by Cohesity for the issues we've come across."

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

"The most valuable aspect for me is that I don't have to deal with media in terms of tapes like our existing system does."

"With Cohesity, you have a template that helps you to backup and restore the right thing to the right place."

"We are now easily managing the data from Helios for all the clusters centrally."

"Fantastic product and the team developing it are top notch."

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

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

More Cohesity DataProtect pros

"Quest QoreStor definitely saved us money."

"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."

"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."

"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 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."

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

"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."

More QoreStor pros

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."

"For Oracle DBs, we have observed a few bugs."

"Non-cloud services need improvement."

"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."

"Their UI requires a manual refresh. It doesn't seem like it updates itself sometimes when you're moving from screens or waiting for a change to take effect, so you have to manually refresh."

"Replication between two Cohesity clusters should be be improved in the next releases."

"The one area where we would like to see additional improvements is with reporting."

"Initial setup can be complex if you need to change IP addresses. Hopefully, they improve that in a future release."

More Cohesity DataProtect cons

"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."

"They need to increase their maximum capacity."

"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."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

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

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."

More QoreStor cons

Pricing and Cost Advice

"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 ROI is huge. Not really measurable at this point, but the price of the unit was a fraction of what a couple hours of downtime could result in."

"The tool's pricing is average."

"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."

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

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

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

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."
