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.

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

"The documentation is good, and it can be integrated with other products."
"The setup is quite easy, just requiring the creation of a vault."
"Our primary use case is for disaster recovery and business continuity and disaster recovery (BCDR)."
"The solution is very easy to use."
"We use the solution across hospitality and healthcare domains. We use it for custom development. It helps us develop a seamless omnichannel for the healthcare industry."
"Azure Site Recovery helps to save costs."
"What I like best about Azure Site Recovery is that it's easier to use because my organization already has Azure as an Active Directory solution."
"The solution is secure, reliable, and scalable."
"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 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."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"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."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"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."
"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."
 

Cons

"Currently, Azure Site Recovery does not support shared disk options. Moreover, it does not support services like AppConfig or App Services."
"Azure Site Recovery does not support shared disk options."
"There is room for improvement in the release of patches, such as ensuring they are properly managed to avoid outages."
"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."
"The pricing predictability and clarity around the final cost of the plan of this solution could be improved."
"Azure Site Recovery's deployment is complex. There are a lot of bugs, and it needs to improve stability."
"The product's performance is an area of concern where improvements are required."
"I conveyed the feedback to the agent, suggesting an increase in the agent count in our VNS in the USA. I also addressed notification concerns, as some issues didn't trigger alerts during a recent call."
"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."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"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."
"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."
"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."
 

Pricing and Cost Advice

"I'm not sure about the Azure Site Recovery pricing, but my organization gets monthly bills from providers."
"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."
"They have a license to pay."
"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."
"Azure Site Recovery is affordable."
"Azure Site Recovery is a very reasonably priced product."
"The tool's licensing is yearly and not expensive."
