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

"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."
"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."
"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."
"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."
"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 works out of the box and it is a key feature that we really appreciate."
"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."
"It can be quickly configured via web pages."
"It is fast, simple, powerful, and has a price without competition."
"We really appreciate the simplicity of the solution."
"Nakivo offers direct support through the graphical interface and this is great to have if you need quick help."
"The automatic backup and replication features are invaluable, saving us time and resources by automating routine backup tasks and ensuring data protection without manual intervention."
"Cloud integration is valuable because the ability to not only backup locally, but to the cloud, has been a great addition to the already fantastic product."
"Technical support responds very quickly."
"The updates are problem-free, so we can keep Nakivo up to date on the server and NAS too."
 

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."
"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."
"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 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."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"There could be better integration with other solutions, such as Amazon S3."
"In the future, I would like to see support for backing up data to more cloud platforms, besides Amazon."
"Sometimes, for some VMs and some Windows Server versions, specifically old versions (aka server 12 or older) fail due to the VSS writer error or locking file system."
"We are satisfied with Nakivo, but if anything could be improved, I think it would be more real-time as opposed to email support availability."
"While the solution provides mostly what we need, it would be ideal if there were some additional feature capabilities for the API."
"An improvement would be to include a general data backup solution that is not only for virtual machines."
"In the press releases, it would be useful to make sure that the manual space reclaim procedure does not have to be performed but that it happens automatically, thus optimizing the use of space."
"While the solution provides mostly what we need, it would be ideal if there were some additional feature capabilities for the API."
