Unitrends users report varied ROI experiences, highlighting efficiency gains but stress understanding infrastructure for optimal results.
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.

Scalability Issues

Sentiment score
4.9
Datto SIRIS offers flexible scalability, with options varying by provider, allowing easy upgrades, but older versions may limit growth.
Sentiment score
6.2
Unitrends offers scalable solutions with ease of management, but affordability is a concern for large hardware upgrades.
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
7.2
Datto SIRIS is reliable and stable, automating backups to prevent failures without user-reported downtime or outages.
Sentiment score

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

Room For Improvement

Datto SIRIS struggles with Mac OS backup, performance, high costs, and requires faster recovery and better integration tools.
Unitrends requires improvements in user interface, setup simplicity, support efficiency, pricing, cloud features, and VMware backup management.
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
I would evaluate the impact of Unitrends' ransomware detection for strengthening our data security measures as somewhat misleading.
Manager, Information Technology at a hospitality company with 201-500 employees
 

Setup Cost

Datto SIRIS offers fair pricing and seamless setup, but lengthy contracts and MSP upcharges might deter some SMB clients.
Unitrends pricing is initially competitive but costly upon renewal; transparency, hardware inclusion, and negotiations often justify expenses.
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

Datto SIRIS offers reliable, efficient backup and recovery with user-friendly features, excellent security, support, and competitive cost-effectiveness.
Unitrends offers reliable backup and disaster recovery with cloud replication, instant recovery, analytics, cross-compatibility, and efficient reporting.
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
The impact of Unitrends' instant recovery features on strengthening data security measures is significant.
Manager, Information Technology at a hospitality company with 201-500 employees

Featured Reviews

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.

Daily recovery tests have validated restore readiness and ensured consistent data protection
The best features of Unitrends include the daily reporting functionality. When backups fail, it is obvious in the logs what caused the issue. Most times it is a credential problem, which is relatively easy to resolve. Though I have experienced a few more challenging issues, nothing has affected critical backup restore functionality. Every time I have needed to restore something, it has worked successfully. The support team is readily available when I need assistance, and they help walk me through issues, solving them within a reasonable timeframe. The automated backup scheduling feature has helped our organization in managing backup timelines and consistency by handling all the work automatically. We set the schedule, breaking things into smaller chunks since our main common area for files is large. I have staggered the backups so some areas receive more attention than others, particularly for less active data. Adding, removing, excluding, and inputting elements is straightforward. The system makes it simple to schedule portions and generate reports on their functionality. The impact of Unitrends' instant recovery features on strengthening data security measures is significant. I generally use instant recovery when restoring specific files or instances where we need data that has changed. The process involves loading the backup, selecting the desired version, waiting for it to unpack, and retrieving the file. Every restore attempt has been successful. I run instant recovery daily in test mode on two virtual machines. I use it to test my domain controller and file server to ensure they communicate properly in the test environment. This ensures that in case of failure, I can activate the recovery and restore server functionality.
