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.

Reliable backups have protected email and servers and now enable rapid ransomware recovery

For the smaller Datto SIRIS devices that are made for backing up one or maybe two different machines, adding more RAM and giving it a better CPU would be phenomenal. Sometimes when dealing with entry-level Datto SIRIS products, you face an issue depending on how much storage there is on there when it's trying to parse through all of the data. It takes a while, and when it comes to data recovery, time is everything. Datto SIRIS should remove the ability to set it up as a NAS-based file share operation system. It seems counterintuitive for something that is made for immutable storage that is walled off so that it can't be destroyed to be allowed to be a local centralized file share that individuals have access to. This seems to be begging for a mishap. Datto SIRIS will require some maintenance when the hard drive gets past 50% capacity, which is Datto's statement on the capacity. You should never use past 50% of the storage locally. Then you have to reach out to Datto directly to get an external hard drive to transfer files to send off the data for it to be shot up to the cloud. We've had a couple of instances of devices not uploading to the cloud because either they were too full or there were failures in certain parts of the file upload to the cloud, which put it into a circle of death where it just kept trying to do the same thing over and over again and had to request assistance from Datto in those situations. Otherwise, if you store it in a dusty cabinet, you have to spray it with a computer duster every once in a while.

Quotes from Members

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

Pros

"Cohesity customer service is the best that I have ever used. They are extremely fast in responding to cases, fixed all issues, and answered every question in a very timely manner."

"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."

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

"The dashboard is very rich and provides details needed for a moderator."

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

"Cohesity is powerful and simple!"

"The ease of use and the GUI have really been most valuable to us. Configuring the system to do what we need is simple and straight forward and a lot of guesswork has been removed. One of my favorite features with Cohesity is Kroll for Exchange item-level recovery. The software is simple to use and fast."

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

More Cohesity DataProtect pros

"Datto SIRIS has changed my recovery time objectives significantly, as it is excellent, taking minimal time, with a simple and smoother interface that allows for a shorter backup process compared to other applications I have used, such as Commvault."

"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."

"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."

"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."

"Datto SIRIS works out of the box and it is a key feature that we really appreciate."

"The best feature of Datto SIRIS is that we are just two clicks away from remoting into the client environment, and we can fetch all the information in one place."

"Since I started using Datto SIRIS, the time to recover data or servers has improved significantly; before, restoring a file or server was very long with the normal backup system, Datto reduced the time much more when I needed to recover a file or a machine."

"Instant Virtualization is the best feature of Datto SIRIS that we have liked so far, as it allows us to boot servers in minutes during outages."

Cons

"The marketplace app stability is still an issue at times."

"Quality testing of upgrades should be somewhat improved."

"Support is good, but some functions are added pretty late, like vCloud Director support."

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

"We have Oracle databases running on Linux servers in our environment and we have found the Oracle backups were quite complex to setup."

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

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

"For the support, I can provide a rating of four only because they initially provide some steps, but later say they are not sure, which is a problem in a production environment."

More Cohesity DataProtect cons

"For improvements in Datto SIRIS, I would suggest enhancing large-scale virtualization performance and providing more transparent pricing, as that is often complex for MSPs and end customers."

"I was disappointed with the processing power and the storage capacity of the ALTO 5 device. Within two weeks of deploying it, I was getting emails that I need to upgrade it."

"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."

"In my opinion about Datto SIRIS, areas for improvement include increasing speed in recovery processes and strengthening security to enhance the product's overall effectiveness in backup and disaster management."

"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."

"The pricing offered to MSPs for Datto SIRIS is okay, but the ability for MSPs, their upcharge when it comes down to small, medium businesses, SMB clients, is actually putting Datto out of the market for SMB clients, especially with the ability to purchase Dropbox and all these cloud-based storage solutions now."

"The cost is higher compared to other platforms in the market like Veeam or Acronis."

Pricing and Cost Advice

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

"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."

"Sizing is important and it is easy to overestimate."

"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."

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

"There is monthly licensing."

"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 pricing model is impressive and very effective."
