7.7
<p>NAKIVO Backup &amp; Replication offers robust scalability, supporting diverse environments with flexible licensing, storage options, and streamlined expansion.</p>

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

Datto SIRIS struggles with Mac OS backup, performance, high costs, and requires faster recovery and better integration tools.
NAKIVO needs improved restore, cloud support, UI, integrations, reporting, speed, support, AI, SNMP, legacy compatibility, and mobile features.
The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment.

Setup Cost

Datto SIRIS offers fair pricing and seamless setup, but lengthy contracts and MSP upcharges might deter some SMB clients.
<p>NAKIVO Backup &amp; Replication provides cost-effective, easy setup and flexible licensing, appealing to small to medium enterprises.</p>
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
The product is affordable even for smaller organizations.

The pricing is very low, and the licensing process makes it easy to obtain any quote.

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.

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.
