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.

Integrated backups and orchestration have protected critical workloads with zero downtime
Pricing is always a consideration because nowadays the price has increased a lot. We bought our system five years ago and we paid in advance, so we are not yet affected by the price increase. However, we are planning to buy another solution in the very near future because the old one is now phasing out. We are planning to buy a replacement of the existing infrastructure and we are facing a lot of cost issues because they increased the price. Previously it was per socket. Now they moved to per core with many other restrictions. Our experience over the last five years has been very positive, but nowadays we find that Nutanix support is degraded. They started reducing their support. Their new functionality is not as stable. Nutanix has added Kubernetes cluster creation, segmentation, and micro-segmentation. Even their support people are not fully knowledgeable. Their support people are trained for VM-based systems, but now their own internal services are running using Kubernetes and containerization. Their support staff does not have enough knowledge to provide proper support. This may be a transition period where a lot of new functionality has been added and the support staff is not yet well acquainted with it.

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."
"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."
"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."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"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."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"For the last five years, we have had zero downtime."
"The most valuable feature of Nutanix Disaster Recovery is the reliability and scalability of being able to swing our workloads across the country."
"The initial setup of Nutanix Disaster Recovery is straightforward and easy."

"The main benefits I've seen from using Nutanix Disaster Recovery include its single platform, which is significantly better than VMware, offering improved security, scalability, and multiple communication options."
"Nutanix Disaster Recovery can be used for snapshots, backup, and disaster recovery."
 

Cons

"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."
"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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."
"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."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"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 major issue with Nutanix is its appliance-based model, which can lead to vendor lock-in."
"The dashboard could be a bit refreshed, and some configuration parts could be less confusing."
"The solution's bandwidth utilization can be improved further."
"The product must allow users to create a production domain on the main site in one hypervisor and a backup site on another."
"Nutanix Disaster Recovery needs to have a feature that can automate manual tasks."
"Nowadays we find that Nutanix support is degraded. They started reducing their support."
"The solution should include a standard license for the object level and file level."
