Senior Technical Engineer at Safezone Secure Solutions Private Limited
The scalability is sufficient for my clients' use cases.
Consultant at a tech services company with 1,001-5,000 employees
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.

Room For Improvement

Barracuda Backup requires better integration, UI updates, improved support, more device compatibility, and AI-driven security features.
Datto SIRIS struggles with Mac OS backup, performance, high costs, and requires faster recovery and better integration tools.
The main area for improvement is integration and support for databases.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
Integration with vendors other than VMware and Hyper-V would make it more competitive.
Director Of Technology at PT Exa Teknologi Indonesia
Adding AI features for security would also be beneficial as artificial intelligence is always helpful from a security perspective.
Consultant at a tech services company with 1,001-5,000 employees
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

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

Barracuda Backup offers budget-friendly pricing with per-terabyte licensing and free device replacement after three years.
Datto SIRIS offers fair pricing and seamless setup, but lengthy contracts and MSP upcharges might deter some SMB clients.
Makes it cheaper compared to other solutions.
Director Of Technology at PT Exa Teknologi Indonesia
Barracuda even provides replacements after three years if a device reaches end of life, without any extra charges.
Consultant at a tech services company with 1,001-5,000 employees
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

Barracuda Backup excels with cloud functionality, fast restoration, effective email security, and reliable support, surpassing competitors in data protection.
Datto SIRIS offers reliable, efficient backup and recovery with user-friendly features, excellent security, support, and competitive cost-effectiveness.
The most valuable feature of Barracuda Backup is that it's on the cloud, so there is no need for hardware.
Consultant at a tech services company with 1,001-5,000 employees
Barracuda email security works effectively with O365, and we have been able to achieve many use cases that other competitive products such as Micro, Fortinet, Trellix, or Forcepoint could not accomplish.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
One valuable feature of Barracuda Backup is that it can be used as thin VMware storage.
Director Of Technology at PT Exa Teknologi Indonesia
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

Featured Reviews

GANESAN K - PeerSpot reviewer
Senior Technical Engineer at Safezone Secure Solutions Private Limited
Rating shows fast restoration and reliable support with scope for improved integration and database backup options
The product needs improvement to become better. For example, we attempted to integrate with Postgres SQL server to backup the database alone, which was not supported. For this reason, we required a separate solution for database backups. While other SQL servers are supported, Barracuda Backup has limitations with database backups. The main area for improvement is integration and support for databases.
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.
