Azure Site Recovery is time-saving, and its features allow us to automate processes and save resources.
Senior Infrastructure Engineer at MIC Global
I estimate that Datto SIRIS has saved around 50% of the time in our processes, as two people can manage everything efficiently, while previously we would have needed eight to ten people without Datto SIRIS.

Datto SIRIS customer service is highly rated for its speed, effectiveness, and reliable support during maintenance and recovery processes.
During a global outage that affected our operations, there was no apology or in-depth follow-up from Microsoft.

Microsoft support could be improved as it rates only a five out of ten, with slow response times and a preference for email over phone communication even in severity B cases.
IT Manager at NTT DATA
We primarily rely on our Cloud Support Partner for support.
Senior Infrastructure Engineer at MIC Global

4.9
Datto SIRIS offers flexible scalability, with options varying by provider, allowing easy upgrades, but older versions may limit growth.
I would rate the scalability of Azure Site Recovery as a nine out of ten.
Chief Technology Officer at a insurance company with 51-200 employees
Scalability is provided because they are offering 99.95% availability.
IT Manager at NTT DATA
Azure Site Recovery is a very scalable product and service mechanism.
Client Relationship Manager at Infomag
You can expand it as much as you can expand it, but if you get the Datto SIRIS 3, it's not going to be as good as the enterprise version of Datto SIRIS 5.
Cyber Security Consultant
The contracts are flexible enough to upgrade or downgrade the product without too much of a penalty.
Managing Director at HB Technologies
Scalability is dependent on the cloud provider we are using, so it cannot be solely judged through Datto SIRIS.
AI/ML Engineer at IT BY DESIGN
 

Stability Issues

Sentiment score
7.7
Azure Site Recovery is highly rated for stability and scalability, frequently scoring between seven and ten by users.
Sentiment score
7.2
Datto SIRIS is reliable and stable, automating backups to prevent failures without user-reported downtime or outages.
The system did go down a couple of times, which impacted our operations.

I haven't had any issues or seen any issues with the ones over the past four or five years.

Room For Improvement

Azure Site Recovery needs better integration, deployment, stability, security, and support, with improved logging, pricing, and platform compatibility.
Datto SIRIS struggles with Mac OS backup, performance, high costs, and requires faster recovery and better integration tools.
If their agent version is mismatched and the health status is critical, you will not be able to perform your Azure Site Recovery.
IT Manager at NTT DATA
There is room for improvement in the release of patches, such as ensuring they are properly managed to avoid outages.
Client Relationship Manager at Infomag
Currently, Azure Site Recovery does not support shared disk options.
Senior Infrastructure Engineer at MIC Global
The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment.
Engineer at a renewables & environment company with 51-200 employees
Saying that it is the network is not detailed enough. We need more specific information about the network.
President & CEO at a tech vendor with 51-200 employees
Strengthening security to enhance the product's overall effectiveness in backup and disaster management.
Infrastructure Engineer at Neurealm
 

Setup Cost

Azure Site Recovery offers cost-effective DR solutions despite complex billing, with average monthly site-to-site replication costs at $225.
Datto SIRIS offers fair pricing and seamless setup, but lengthy contracts and MSP upcharges might deter some SMB clients.
It was not the expensive part of our costs.
Chief Technology Officer at a insurance company with 51-200 employees
A major advantage is that you do not want to pay any more for huge costs to build a DR site.
IT Manager at NTT DATA
The pricing of Azure Site Recovery is around a four out of ten, being somewhat cost-effective.
Client Relationship Manager at Infomag
The only issue is that a lot of people are looking to cut costs, especially right now, and Datto has priced itself out of one of the largest parts of the U.S. market.
Cyber Security Consultant
It's a high-level solution, and the price is correct for me.
Engineer at a renewables & environment company with 51-200 employees
Thoughts on pricing indicate that it is handled by a different team, varies based on specific solutions and storage capacities selected by organizations, and is generally fairly priced for the value provided.
Infrastructure Engineer at Neurealm
 

Valuable Features

Azure Site Recovery is praised for seamless failover, ease of use, compatibility, but may be costly for smaller clients.
Datto SIRIS offers reliable, efficient backup and recovery with user-friendly features, excellent security, support, and competitive cost-effectiveness.
Its time-saving aspects allow us to write PowerShell scripts to automate failover processes.
Senior Infrastructure Engineer at MIC Global
Azure provides a 99.99% SLA for their uptime, ensuring that even during outages due to patch releases, there is no data loss, merely hindered accessibility.
Client Relationship Manager at Infomag
The most valuable features of Azure Site Recovery are its ease of use and speed of recovery.
Chief Technology Officer at a insurance company with 51-200 employees
My experience with the one-click disaster recovery feature is that it simplifies the process significantly, allowing for rapid recovery and integration with backup and disaster recovery solutions, automating tasks while providing security against various threats.
Infrastructure Engineer at Neurealm
In the last six years, none of my customers faced a ransomware attack, and we use this functionality for system outages and physical server crashes.
System Engineer II at a tech services company with 1,001-5,000 employees
The reporting via email from Datto SIRIS for me, my customer, and my team shows that every single backup is okay or if there is a problem because the snapshot for the server is broken or another problem that I can address systematically.
Engineer at a renewables & environment company with 51-200 employees

IT Manager at NTT DATA
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.
James Melton - PeerSpot reviewer
Cyber Security Consultant
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.
