Long-term user praises cost savings and reliability of disaster recovery solutions
There is only one thing to note: the agent has to be up-to-date when SCCM or any third-party tools are doing patching activities. If their agent version is mismatched and the health status is critical, you will not be able to perform your Azure Site Recovery. Recently, I worked with a mass issue related to Recovery Services Vault, and the VM support engineers are taking a lot of time to extend support to the customer. When you raise a call, they wait too long, and even if you request an engineer to set up a call for severity B cases, they are not ready to communicate over the phone, preferring email instead.

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

"Our primary use case is for disaster recovery and business continuity and disaster recovery (BCDR)."
"The solution is very easy to use."
"The setup is quite easy, just requiring the creation of a vault."
"Site Recovery's most valuable features include its user-friendly console and the ease of migration."
"The solution is secure, reliable, and scalable."
"The most useful thing is that it provides a snapshot of your environment in about 15 minutes. It is stable, and it always works. It is also scalable and easy to set up."
"The most valuable features of Azure Site Recovery are its ease of use and speed of recovery."
"Azure Site Recovery's automated file synchronization was a game-changer in managing legacy systems."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"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."
"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"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 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."
 

Cons

"Could have more integration with other platforms."
"There is room for improvement in the release of patches, such as ensuring they are properly managed to avoid outages."
"It would be good if we could replicate the solution to multiple locations simultaneously because we are currently allowed to replicate to just a single location."
"Recently, I worked with a mass issue related to Recovery Services Vault, and the VM support engineers are taking a lot of time to extend support to the customer."
"In the newest version of Azure Site Recovery, the configuration was a little more complex, so this is an area for improvement."
"The solution needs to improve replication and failover processes. We are still looking for improvements in the cost baseline."
"When it runs, it runs well but when it doesn't run, the solution needs to make it clearer as to why and what the troubleshooting process is. All this would be possible if the error logging was streamlined a bit."
"Currently, Azure Site Recovery does not support shared disk options. Moreover, it does not support services like AppConfig or App Services."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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."
"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 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."
 

Pricing and Cost Advice

"Azure Site Recovery is affordable."
"I'm not sure about the Azure Site Recovery pricing, but my organization gets monthly bills from providers."
"They have a license to pay."
"The tool's licensing is yearly and not expensive."
"Azure Site Recovery is a very reasonably priced product."
"The tool is expensive. What is expensive to me might not be expensive to you. As I mentioned, we seek ways to reduce our costs. If the price goes down, that would be great. I rate the tool's pricing a six out of ten."
"Azure Site Recovery is neither very expensive nor very cheap."
"It should have more straightforward billing. The billing was what got funky. It was really cheap. We would pay based on the usage. We paid around $225 a month for site-to-site replication."
