Adopting advanced convergence and seamless management elevates data protections
While there are improvements to be made, such as providing support for older systems like IBM iSeries and tandem systems from HP, the solution overall shifts from older methods to modern practices. Customers looking for features that older systems provided might find gaps, but these are typically for very specific needs.

Backup platform has significantly improved recovery speed and reliability for critical outages
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. The use of Datto SIRIS has significantly improved our Recovery Time Objectives. We have been using other software like Veeam and Microsoft Backup as well, so we have found Datto quite competitive to them. Our experience has been good so far, our clients are satisfied, and we have been handling outages effectively. We have not had the opportunity to use the One-Click Disaster Recovery feature because the last time we experienced a phishing attack, it was resolved and did not escalate to a disaster scenario, so we did not need to use that feature. Datto SIRIS improves reliability by providing storage space that enhances overall dependability. The centralized dashboards in the Hero Reports feature have been most beneficial for our IT reporting needs. The Hero Reports feature provides extensive capabilities that include the specific points we need for our demonstration. Even if we want to use these features to train machine learning models, they are very useful for us, and we do not need to perform much work on the data to extract those features. It has helped in reducing disaster recovery testing hours because it has features that help us by monitoring malicious activities throughout the database and notifying us of any fluctuations in normal behavior. Datto SIRIS is good at assessing effectiveness regarding ransomware recovery, and it is competitive in the market. However, the only concern we have been thinking about is its pricing. The pricing of Datto SIRIS is more expensive than Veeam and Microsoft Backup. On the other hand, it provides many more options and much greater feasibility.

Quotes from Members

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

Pros

"The dashboard is very easy to use."
"It's stable."
"Cohesity is a cost-effective storage designed for secondary or archival data. It also integrates well with a number of other systems, like VMware, Pure Storage, or AWS with its large array of APIs available to the user."
"We can run test scripts on production data."
"The dashboard is very rich and provides details needed for a moderator."
"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."
"The support is awesome. They are very fast, competent and friendly."
"It offers an easy, quick backup and restore of files and VMs. Also, the "Google-like " search for files is awesome."
"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."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"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."
"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."
"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"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."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
 

Cons

"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."
"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."
"I'd like to be able to pause a backup while it's running and have it resume when I tell it to resume."
"At times, you may click the wrong server or click too fast and accidentally restore a cluster of servers. It would be very helpful to have a cancel option under restores."
"The rack mounting instructions did not appear to be correct, but we were able to overcome it."
"In terms of what could be improved, it just needs some maturity."
"We are waiting on the AIX agent to be released."
"We would like it to have more capabilities for different kinds of PaaS or SaaS services in the Azure cloud, such as Azure SQL or Azure Cosmos DB."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"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."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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."
"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."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly. It is cheaper than other backup solutions."
"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."
"We purchased support from Cohesity to ensure that should we face an issue, we don't have to deal with different service providers."
"Sizing is important and it is easy to overestimate."
"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."
"There is monthly licensing."
"The solution's pricing is quite high, more so than that of its competitors, Veeam, Veritas and Rubrik."
