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.

Quotes from Members

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

Pros

"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"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 works out of the box and it is a key feature that we really appreciate."
"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 positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"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."
"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."
"The backups, especially of the incremental type, are really quick (ranging from five to 10 to 45 to 50 minutes depending on the size of the VM)."
"The simplicity of installation and the intuitive user interface have made it easy for our team to quickly set up and manage the backups without requiring extensive training."
"They reply immediately to any query raised from us as a technician or consultant and they know the pulse of the market and keep updating the features in such a big way."
"It is affordable."
"The easy management and a good overview are the most important aspects."
"Nakivo has improved our organization largely due to the fact that it is an extremely robust backup system."
"The product license and support delivery have been great!"
"It is easy to set up using the included virtual appliance and also includes agents for most NAS systems."
 

Cons

"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"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."
"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 cost is higher compared to other platforms in the market like Veeam or Acronis."
"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."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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."
"My first thought was maybe the GUI could be improved, although it works."
"I would love to see BackBlaze B2 implementation in the future, as that would be our preferred cloud destination, but Amazon and Wasabi are both very great choices in the meantime."
"The way encryption is currently working could be improved. Currently, it's not possible to encrypt the backup to an NFS share directly. It needs to have the encryption within the Transporter/VM to enable encryption, which isn't optimal. So I'm hoping that in the near future this function will be implemented."
"What must be improved is the response time to technical support requests."
"Right now we know that Nakivo has the ability to back up as an incremental process and restore backups across several criteria. However, it would be good if we had the ability to backup a system like PostgreSQL."
"Updating VM Tools on a replicated VM could be better."
"We'd like to see more cooperation with Synology. It can be enhanced to get updates published faster to Synology's store."
"Using an independent bootable media to restore full physical machines would enable physical machines that may be serving as Nakivo Director or Transport machines to be reliably restored to service without undue delay, ensuring that an enterprise's local environment remains intact."
