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.

Easy to work and offers features for tape backups, disk backups, and whatever you want
NovaStor NovaBACKUP is still working on new features because they listen to the customers and integrate their needs into new versions. You can see they make progress with each new version. They are much faster than IBM, where you sometimes have to wait years for new features. It is very quick and fast. NovaStor have big competitors like Veeam, which is very fast and aggressive. It's good, but it depends on the price. I think NovaStor might be cheaper. They have a direct connection to their developers and sales teams, which makes getting answers very fast. Veeam has a lot of features, like a special reporting tool. However, I've heard from some customers that Veeam wasn't always the right decision because it couldn't work with their environment. But Veeam has aggressive marketing, which is why they are probably in first place at the moment, besides Commvault. IBM has lost its competitive edge and is trying to catch up, but it might be too late.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Since I started using Datto SIRIS, the time to recover data or servers has improved significantly; before, restoring a file or server was very long with the normal backup system, Datto reduced the time much more when I needed to recover a file or a machine."
"Datto SIRIS has changed my recovery time objectives significantly, as it is excellent, taking minimal time, with a simple and smoother interface that allows for a shorter backup process compared to other applications I have used, such as Commvault."
"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"The best feature of Datto SIRIS is that we are just two clicks away from remoting into the client environment, and we can fetch all the information in one place."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"Instant Virtualization is the best feature of Datto SIRIS that we have liked so far, as it allows us to boot servers in minutes during outages."
"It's the easiest way to configure it."
"It is a very good and easy-to-use tool for non-technical people."
 

Cons

"I was disappointed with the processing power and the storage capacity of the ALTO 5 device. Within two weeks of deploying it, I was getting emails that I need to upgrade it."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"In my opinion about Datto SIRIS, areas for improvement include increasing speed in recovery processes and strengthening security to enhance the product's overall effectiveness in backup and disaster management."
"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"The pricing offered to MSPs for Datto SIRIS is okay, but the ability for MSPs, their upcharge when it comes down to small, medium businesses, SMB clients, is actually putting Datto out of the market for SMB clients, especially with the ability to purchase Dropbox and all these cloud-based storage solutions now."
"For improvements in Datto SIRIS, I would suggest enhancing large-scale virtualization performance and providing more transparent pricing, as that is often complex for MSPs and end customers."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"The price of NovaStor NovaBACKUP is an area that can be considered as a weakness or drawback, where improvements are required."
"The room for improvement lies in the compatibility of NovaBACKUP with older operating systems."
