4.9
Datto SIRIS offers flexible scalability, with options varying by provider, allowing easy upgrades, but older versions may limit growth.
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.

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.

Ankit Gagneja - PeerSpot reviewer
Cloud Solution Architect at Tata Consultancy
Hybrid backup strategy has improved recovery orchestration and now supports flexible DR planning
I think improvements could be made in Commvault Cloud. Lately what I have seen is that there are AI capabilities that different data protection organizations are coming up with, which basically revolves around tiering of not frequently accessible data to glacier kind of storage, plus bringing in a high level of compression and deduplication capabilities. All those features I believe are there in other customers and they are bringing in new use cases from the AI perspective which I have not recently seen in Commvault. I have seen that Dell does have such features. We recently pitched a solution to the customers where we talked about data tiering and the other AI use cases, identifying the data by itself and autonomously taking decisions on how to tier the data between the different storage classes that we have. Those kind of capabilities that we have proposed to the customer as far as the partner solutions are concerned. I would like to see AI capabilities in Commvault Cloud. The rest of the features pretty much align with the other enterprise solutions that we have in the market. It is just the AI capability that is being asked by the customers as well as that I see missing with Commvault.

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.
