Cohesity DataProtect integrates well with many of today’s top solutions, including, but not limited to:
Reviews from Real Users
One reviewer, who is head of IT infrastructure at Kampmann says, “Cohesity really is a Next-Gen Data Management Software,” and goes on to indicate that Cohesity “works flawlessly with easy replication of backups and numerous supported backup sources.”
Another user, who is a senior network engineer at a legal firm, relates that "Cohesity is a robust and feature-rich solution"
Cohesity DataProtect was previously known as Cohesity.
We use two versions — one version is deployed on the cloud, the other version is on-premise.
I am the primary backup operator. There are two to three people that assist me.
The ability to essentially instantly recover a VM and have it run on the Cohesity Platform while all those bits are technically being recovered in the background is useful to us as well.
We've certainly had our share of problems with it. Since March, I think we've opened about 150 tickets with Cohesity for support for various issues; we're averaging 4 tickets a week with them. We're working through the issues that we have, but it seems like, on many levels, we're rewriting their code to make it work in our environment.
We, as a city, a local government — we have a lot of old legacy hardware, old operating systems, and old applications.
Commvault was pretty good about supporting those legacy operating systems that we still have in our environment, which includes things like Windows 2000 and Windows 2003. I understand that Cohesity has to keep up with the times and everything, but our inability to back up some of those older platforms is a pain point for us.
I'd like to be able to pause a backup while it's running and have it resume when I tell it to resume. Unfortunately, I can't do that today. I have to basically kill or cancel a job — that's one of my biggest pain points. I'd like the ability to backup clustered file servers, which I can't do today. I have to back them up as NAS devices basically, as opposed to Windows Servers. Those are my two biggest pain points.
I have been using Cohesity DataProtect for roughly nine months.
One of our Cohesity nodes apparently partitioned itself off from all the other nodes.
We have a five-node cluster, and that was preventing one of our SQL backups from running; it sat there for roughly two days in this partition state. Then, just as suddenly as it partitioned itself, two days later it unpartitioned itself, and the backup eventually completed. It took two days to back up what normally takes about 20 minutes.
Nobody's really been able to explain anything about that to me, other than that somehow a node partitioned itself away from the cluster. I don't know what that means, but yeah, it screwed us up for a few days.
We've had to add nodes — that was pretty simple. We did run into some problems with the IPMI Lights Out Interface, but I wasn't involved in that. As far as I know, once we worked through that issue, it just added itself to the cluster, and all of a sudden we had 20 terabytes of additional storage and a bunch of extra CPU and RAM.
Sometimes, getting help from support can be difficult. On a scale from one to ten, I would give their support a rating of three.
Although we have full support with them, 24/7, it seems like we always fall into this email support model first, as opposed to just picking up the phone and calling me and telling me exactly what the problem is. When we speak over the phone, the issue is usually resolved within a few minutes.
But it takes four weeks to get to that point, after a couple of weeks of exchanging one email a day. They'll say, "Oh, we'll try this." Then I say, "Okay. I tried that." After a couple of weeks of that, I feel compelled to escalate matters through our account manager — "Why can't you just pick up the phone and call me? We can fix this right now."
We used to use Commvault but we switched to Cohesity DataProtect mainly for cost reasons.
We also switched to Cohesity for the ability to backup to the Cloud. The version of Commvault that we were using at the time was tape-only, and we didn't want to pay Commvault to upgrade.
It wasn't an easy install for us.
Like I said of our legacy environment, we had an old VMware environment that the latest supported versions of DataProtect would not backup through vCenter. We had to build multiple legacy Cohesity environments to try to get those backups so that legacy VMware environments could work. It probably took five or six tries before we finally said, "Screw it, we'll upgrade the VMware environment". We were finally able to do it because we were able to get some licensing from another department that they were no longer using. Otherwise, we would still be stuck on legacy — with Cohesity backing up legacy VMware.
As always, there was a learning curve that comes with learning a new product, and trying to get our DBA's involved in SQL backsups, etc. That's something that they've not really been involved with in the past with Commvault — we always managed that. There was some learning curve for them as well.
Overall, it's a good product when it works — don't hesitate to go with it, just make sure you get a good implementation engineer from Cohesity that can answer all your questions. Be sure to ask questions every step of the way. They also have a pretty decent training program; I've gone through a few of their training courses and those are useful. Definitely, I would recommend that anybody that's putting it in for the first time, definitely attend a couple of their all-day, six to eight-hour-long courses, and take some of their administrator-type courses.
Overall, once we worked through some of the problems we had, it's been pretty good. Not counting the tech support who I rate low, but the overall product, on a scale from one to ten, I would give Cohesity a rating of eight out of ten.
We were looking to replace our legacy tapes and Veritas Backup Exec. We were tired of spending money on tapes and the time it took to physically handle and transport the tapes as they cycled through the system. We were also looking to do something to get rid of some of our older legacy NetApp devices. In the end, we were looking for a solution with redundancy and support for encryption for data at rest. We were also hoping for something that would enable on-prem storage, but at the same time, give us cloud capabilities down the road when the organization was ready to make that leap.
We were able to eliminate tape backups by utilizing Cohesity to backup our VMs. We then replicated the backup data to a second offsite Cohesity cluster. In the future, we will archive older backups to the cloud as well via Cohesity. We have also been able to utilize Cohesity as a replacement for our older legacy NAS devices - serving up unstructured data on file shares. This was a major win for us, as it greatly simplified our environment and we saw a substantial increase in speed from our legacy NetApp devices.
The overall ease of implementation and use has been outstanding. Upgrades are easy because of the way that redundancy is built into the Cohesity solution. You simply go to the web-based GUI, download the update, and apply.
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.
The engineering team also seems to be working hard to constantly add new features. Since we purchased the product, Cohesity added the ability to perform Office 365 backups and AD backups at no additional cost. The features just showed up in the new release, which was great.
There have been a number of improvements since we purchased the product two years ago that has since made it even more attractive to users. Things liked education and training have been a greater focus. Cohesity now offers "Cohesity Academy" for education, and recently launched Cohesity User Groups for people to join other Cohesity users in discussing best practices, use case scenarios, etc.
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.
I've used the solution for about two years.
The stability is absolutely rock solid. I'm not aware of any issues with file services and the backups have been 100%. We have not had any file share outage or issues with SMB which is awesome as SMB fileshares were a critical part of decision to purchase Cohesty.
The solution is very scalable. If you want to buy the boxes, this solution will work at the largest of enterprises.
Support has been very good - particularly in the last 6 months. They seem to have grown the support organization as the install base has increased and the quality of the engineers is very good. The remote support functionality in the product makes it very easy for Cohesity staff to diagnose problems and either guide you through the fix or even perform it themselves.
Cohesity sent a local sales engineer out and in an afternoon we had it racked, networked, and backing up.
Cohesity sent a sales engineer out and it was done in an afternoon. They made the whole process incredibly simple.
It's hard to estimate a dollar value for the peace of mind in knowing that my files and backups are there and they work. In the face of ransomware and other threats, I can roll back in a few clicks. Upgrades are simple and Cohesity has a security focus. I wish we could have made the change years ago.
The costs vary, but the vendors will sometimes work with you depending on your purchase and what time of year it is in order to make deals happen. The Cohesity licensing was pretty straightforward, which was also attractive in that we didn't have to license a whole bunch of features. Everything was bundled together.
We looked at Rubrik, which was pricier and did not offer file services at the time. We also looked at a budget play in Storage Craft but were not sure if the product was going to have enough market support to continue. Also, the features seemed rough compared to Cohesity, which felt more polished and finished.
We have been very happy with the performance and ease of use of the solution. Support has been very good - even as they have grown and scaled up in size.
We use it for both local VM recovery, exchange, SQL recovery, and disaster recovery.
We have an on-premise exchange environment and it is really large and sensitive to backup impact, where it'll actually slow down the mailbox servers due to the stunning effect of trying to snapshot the VM. We previously had to do dedicated backup servers, which was an additional consumption of on-premise resources of storage and compute. When we moved to Cohesity, we were able to target the passive copies of those databases so we no longer needed to have dedicated backup servers for the exchange environment, thereby reducing both the footprint of exchange and the resources consumed to support of the backup server.
I found value in the instant recovery with DataMove. I found value in the protection group model for applying policies to VMs. And in the overall UI navigation and the way that the application is laid out in the web browser.
In terms of what could be improved, 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. I would say that is an area for improvement, and I would also say that they have room for improvement for being able to roll back to previous versions after you've upgraded. They don't have a good rollback methodology to go back to previous versions if there is a problem with the new version.
I have been using Cohesity DataProtect for two months.
I feel like it's very stable.
We are running with a full no-redundancy, so we can lose an entire node in the clustering and it will operate without any downtime.
Cohesity DataProtect is very scalable. You can add resources just by adding additional nodes to the cluster and it seems to be able to scale out as large as you need it to.
It is used primarily by engineering and by a couple people in the app team on the SQL side. I'd say maybe half a dozen people total use it in our organization and they're in a combination of apps and engineering.
Deployment and maintenance are all done by me and my counterpart for the most part, just senior engineers on the engineering team. There are just two of us that are primarily handling that.
It is being used extensively in both of our data centers for all virtual workloads, as well as the SQL Server and exchange application level workloads. Those are our use cases primarily for those applications and the VM.
They have excellent technical support. I give them high marks for that. They all seem to know the product well and be willing to assist with things and have experiences all around with the support team.
We previously used Rubrik and we switched due to Rubrik tending to focus more on public cloud solutions over the past couple years and also the overall price of the solution - Rubrik was very expensive. We wanted to have more of a competitive product up against it.
Initial setup is straightforward.
It took one day for each site. We have two sites. We deployed each site in one day for a two day deployment total, and then our overall deployment strategy was to begin ingesting at the VM level and then start focusing on the agent-based deployments to equal an exchange.
In terms of ROI, the time of management is lower than what we were previously using so we are getting some cycles back from an engineering perspective. Also, we were able to reclaim our exchange environment in terms of resources, so there was some return there that we were able to recoup immediately, and then just the overall cost across the duration of the licensing and the hardware is expected to be lower than what we previously had.
It is on a yearly license. It actually includes the cost of the hardware, as well. So the cost of the hardware and the licensing is all rolled into a single bundle with the support.
Before going with Cohesity, we spoke with Pure, Commvault, and with Rubrik and Cohesity and Rubrik were identified as the two finalists and we did a proof of concept for both of those.
My advice to anyone considering Cohesity DataProtect is to try it out because the performance seems to exceed the competitors in the market. If it fits well in your organization or your use cases, then give it a shot.
On a scale of one to ten, I would rate Cohesity DataProtect a nine. I did a lot of research into the different products and found this one to be pretty much top across the board and after using it, we are very happy with the performance and the results that we are getting.
We primarily use this product for backups, reporting, and auditing. As we are a publicly listed company, we rely heavily on the reporting that comes out of Cohesity to ensure that we are compliant across all aspects.
The backup and restore solution is a big step forward from our last solution and packs more than just backup in a box, allowing for additional features such as Disaster Recovery and utilising the space available in the cluster for storing files.
The auditing and reporting features are as important as the backups themselves.
We moved over from another backup solution that wasn't as innovative, which made it an easy solution to move away from. Cohesity uses up less rack space in the datacentre and allows for more than just backups, paving the way for more hyper-converged solutions, not just physically.
The initial contract with Cohesity is an improvement in terms of pricing above our previous solution but it remains to be seen what will happen after the contract comes to an end. The fundamental tasks of backups are restores are ahead of its game, relative to our previous solution.
The backup and restore feature is the most valuable.
Instant recovery options are a big benefit for urgent restores, as we don't need to wait for hours or days for a restore to complete before being able to access the files.
The restore to the appliance itself allows for faster (instant) access that saves us from waiting for the restores to happen to the datastores/volume/containers, which can take upwards of weeks in our case if we were to restore the larger VM guests.
We have seen many iterations of this such as restoring to the cloud but the outcome has always been a hit-and-miss solution.
The canned reporting could be improved. 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. This is something that even our last solution had in place already.
Error reporting could also be improved. Rather than 'errorcode -2', it needs to be more descriptive or at least, provide KB articles related to the error or problem. This would save time in creating a ticket and try to describe to the support engineer what happened to cause an 'errorcode -2' that most of the time, we don't know either.
We have been using Cohesity DataProtect for seven months.
Stability-wise, so far so good.
The initial implementation requires a lot of babysitting and reporting on issues is a bit lacking. Hopefully, you've purchased a good support contract to help with those teething issues.
The solution is very scalable. It doesn't require a replacement appliance to expand for more capacity. Simply purchase another block/node and it's done.
My experience with support is mixed. There are times where the response and resolution are quick but at times, there are large gaps in the response. I'm not sure whether this is timezone-related.
We switched over, as the previous solution was very lacking behind in innovation. It was missing basic features such as finding VMs and we were told to simply use "ctrl+f" to find them. However, this didn't help if the screen spanned across multiple pages.
The initial setup was straightforward, as we engaged with the company to help with the deployment. As long as the provided templates are completed and networking is done properly, it should be a smooth ride.
Our deployment was completed by a mix of both. The vendor team was very qualified and personnel was made available at each region to assist the local teams with implementation.
This is difficult to measure and quantify but the time saved across the regions baby-sitting the previous solution would be about eight hours per week.
My advice is to always negotiate for better pricing.
A contract with any backup vendor will always be a long-term deal, so think ahead and force them to sharpen their pencils. Never sign up without evaluating the price of other vendors over a three to a five-year term.
Although the NPS score was rated highly, this should not be the only factor to consider. There may be other factors involved that affect this score and as mentioned, backup solutions are a long-term deal. Not many companies will be willing to jump ship, risking their backups that are kept on proprietary platforms.
Our primary use case is for backup and DR. We have two clusters. One is all-flash. The other is a DR cluster with spinning disks. We use the all-flash to host shared storage, as well as a number of other services. We also use a number of other features such as SmartFiles. SmartFiles allows us to host all of our shared storage on the all-flash nodes, while keeping a DR ready copy on the DR cluster. This frees us from the constant management of a traditional Windows SMB environment and allows us to maximize up-time.
The seamless backup and restore functionality has made file recovery and patch Tuesdays inconsequential. VM and SQL cloning in the test and dev feature sets allow us to immediately bring up backups both to test or for immediate availability (if needed). The VM can stand up within the Cohesity cluster and live vMotioned to our production VMware cluster.
While other solutions might take hours to recover a VM, we can instantly bring one up and have our users back to work. The file recovery is equally simple, with the ability to clone entire SMB shares with a click.
Cohesity DataProtect is just one suite of features. Obviously, instant recovery and a live VM environment to bring up backups in would be the top feature set, however, there is so much more.
ShareFiles allow for SMB shares to be stood up in minutes. Currently, we store our surveillance, user shares, department shares, and a number of other internal shares on SmartFiles. We even have a witness share for our SQL clustering.
With instant DR failover using SiteContinuity, we are able to keep our files available no matter the situation.
DataProtect is a full-featured backup suite. Better support for legacy platforms would be nice, but we should be moving off those anyway.
The marketplace app stability is still an issue at times. The company is very quick and hotfixes are released regularly. Their support is really fantastic, and I’ve only had one notable outage relating to an update. Ultimately it boiled down to a configuration error on my part, so I suppose I can’t blame them too much for that.
Now that we have added additional nodes stability has been much better.
I've been using the solution for two years.
With only one (self-inflicted) outage, I would say it is very stable.
Adding nodes is trivial and can be scaled out to petabytes easily.
I’ve had many experiences with Cohesity support. They clearly keep support a primary concern and I’ve never had a bad experience. Recently, I had to submit a P1 case, and I had two top-tier engineers on the phone within 10 minutes.
Previously we used CommVault. We needed a more agile and robust solution.
The setup is simple. We simply had to assign the interfaces an IP, set up our port aggregation, and create the cluster.
We had Cohesity support come on-site to assist, however, we were there every step of the way. The Cohesity PS teams are very knowledgeable.
Unfortunately, I am not privy to the business side of this decision, however, we've recovered from ransomware successfully without paying any ransom. Considering the organization wouldn’t exist any longer without Cohesity, I would say it was worth it.
I would advise others to invest in their backup infrastructure. It is literally the most important solution you will purchase for business continuity. As a ransomware survivor, I cannot stress enough how valuable this solution is.
We did evaluate other solutions and Rubrik was a major contender. Ultimately, Cohesity won out with a Cisco Hyperflex platform and superior support.
One of the most valuable features is the restore functionality that they offer.
They are really ahead of the curve concerning development and telling it to the market. We are a partner, and we know that sometimes a certain technology about which they have been telling a broad audience is not really production-ready, or it is in a feature release. There is always a difference between general availability and general deployment. Sometimes, we sell the feature, but it is not in the GA. It is in one of the future versions. That's one thing.
The other thing is that they lack visibility. When talking about backup, the first thing that everybody says is Veeam. If you are talking about the appliance part of the backup market, Rubrik is the first one they're mentioning, but a lot of the Rubrik customers don't know Cohesity.
I would like to see the management of multiple nodes inside a tenant. If you want to manage a Cohesity environment, you either go on a per-node base, and you can hop from one node to the other, or you need to implement their SaaS capability but it always needs an internet connection. We would really like to have some kind of local management entity so that we can see all the Cohesity nodes in a customer environment and manage those nodes centrally. That's something that we would really like, and they are really working on it.
I have been working with them for the past two and a half years.
It is stable.
It is very scalable, and the nice thing is that you can use it in combination. You can use it as a backup solution, but you can also use it as a file system solution with NAS capabilities.
They're really good. A technical support guy can be a co-owner of a case. They are very good at connecting with the customer. The tools they provide to solve problems are very useful.
We also use Commvault. We see Commvault more as the Swiss army knife for backup solutions with a lot of features and functions. When we want to make backup more easy and robust, then we're positioning Cohesity. We see that one part of the market really likes the Commvault features and functionality, but there is another part in the Dutch market that says, "I don't want all that complexity. I just want it set and go," and that's when we're positioning Cohesity.
It is really easy.
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.
You have to get the network right. The network stuff is really important for Cohesity, but we see that its implementations are way simpler than, for instance, Commvault implementations. For all the features, follow the documentation. There is a really good setup guide with some fill-in forms that you can use to get all the details you need, and if possible, consult a partner just to know all the functionality that Cohesity is offering. We sometimes see that people buy a Cohesity appliance, and they're just setting it up rudimentary for backup. When we come in and talk to the customer, we say, "Hey, this is also a feature. You can also use this. Have you looked at this part?" So, it is feature-rich, and you need to consult a partner to get to know the product better.
I would rate it a nine out of 10. It is a real robust product.
We use the Data Protector to back up all our VMware virtual machines, as well as a SQL Server and Microsoft Exchange. We're not that big of a company anymore. We have three people who know the product: two specialists and someone from second-line support who can handle the tickets.
The most valuable thing about Cohesity is how it operates as a whole. We are very satisfied with the product as a whole—all the backup functions, the data protection functions. We are very satisfied with those, and the product is very simple to use.
We have had our share of minor bugs over the past two years and a few bigger ones. But I think it's because the product has so many features, and they try to add new stuff reasonably quickly. For example, Cohesity adds certain functionality in what they call a "feature release." This doesn't mean a long-term release. They added new functionality very quickly, and it was things we needed that were not yet available in a long-term release. When I say "long-term release," I mean one that is more static and gets updated once every few months. We wanted the feature, but we had more issues than some of us might've liked.
On the other hand, they managed to fix all the bugs without significant issues like data loss or anything like that. So it was more an inconvenience than it was a real problem. But if I have to have any criticism of them, maybe it's that. There are some minor improvements on SQL Server backups that we are waiting on, five services. We had one problem that will be solved in one of the subsequent releases, but those are small things. We are not waiting on any major stuff. The product currently meets all our backup needs.
We have been using Cohesity for just two years.
Cohesity's stability is very good. We haven't had any major issues with that.
I would say Cohesity support is somewhere in between good and very good. But, of course, it depends on which region you get. We know that if we log a ticket before noon here in Belgium, we are not in the region where we want to be. It's something we told Cohesity about, as well. We asked them if they could arrange it so that our ticket will always get picked up by the people in Cork. For one thing, they're in our title. They're also much more capable compared to the other regions. But that's our experience. Generally, we are very satisfied with the support we are getting.
Setup is pretty simple, especially compared to the product we had before. It was an older legacy product that was much harder to implement. We deployed with the help of an integrator, but we do all the day-to-day maintenance on the product by ourselves.
We paid for the entire solution because we have done a few expansions already. I think it's between 400 to 600k. That is the price for the complete system, including the hardware, the support, the subscriptions for the software, I think for four to five years.
I rate Cohesity nine out of 10. So, I would recommend it because it's quite a simple product and can do a lot. With the last product we used, you had to be a specialist to navigate in it. It's a much more straightforward and modern interface—very intuitive to use. And the speed of the backups, we do much more backup than we ever did before. So, I would certainly recommend it, yes.
I'm using Cohesity DataProtect to do product demo's for my customers.
The enterprise search and instant restore are pretty valuable. Also, the Helios stuff is pretty good and the SAS engine for ransom malware detection.
I think Rubrik and Cohesity are pretty similar in terms of the user interface and user experience, but 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.
We've never had a problem with stability.
It's easy to scale with their clustered architecture and add to the cluster. The builds join the cluster on their own without really having to do much. Most of our clients are mid-sized enterprises.
I rate Cohesity support eight out of 10. I haven't had any issues. I guess it depends on who you talk to and what their experience was, but I think they do a pretty good job with Helios, where their support team can access the environment. I would say it's a little more modern approach than IBM, which has a 20-year-old support model, i.e., you capture and upload the logs. With Cohesity, you get a little more real-time visibility from support.
Then again, most of my support inquiries are in the pre-sales context, so our customers are the ones using it, but I haven't heard of any significant problems. Still, I think some of these companies are experiencing some growing pains. They're growing fast. Sometimes they get a little ahead of themselves, and maybe the support could be better.
Setting up DataProtect is pretty straightforward.
I'd say the price of DataProtect is reasonable.
In some cases, a greenfield approach is a better fit for the customer's needs. The marketplace is robust. They can work as a filer and replace certain file service workloads, like user share type. You're not going to replace a NetApp or an Isilon solution necessarily, but you can do some consolidation. For example, one customer wanted to do their virus scanning right on the cluster, not their hosts. So you can run Tenable or something. One customer liked it because we could run the Christie Bare Metal Restore. They had physical systems and wanted to have BMR.
I would give Cohesity DataProtect nine out of 10. It's a relatively complete solution. If you are thinking about implementing it, I would suggest looking at opportunities to consolidate some file workloads. Many customers are still doing dump and sweeps, and this is a good platform for it. You just dump, and you don't have to do a sweep. Now, the question is: Do you want a lot of NFS mounts in your environment? But it's good. You can buy this data platform that they call "SmartFiles," I think. You can have a 100 terabyte cluster, with half of it devoted to file services and the other half doing backups, then license it accordingly.
