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.

Reliable and cost-effective
One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication. Currently, it lacks the capability to automatically stop backups if it detects a virus or suspicious network activity, as some third-party solutions can. Having AI-driven analytics to identify anomalies and halt backups during potential attacks, along with notifications to administrators, would be valuable. Additionally, providing a dashboard for monitoring the backup environment's security would be a beneficial feature. These improvements would help address security concerns and make Synology more competitive in this aspect.

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 positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"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 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."
"Datto SIRIS works out of the box and it is a key feature that we really appreciate."
"Synology DSM is very easy to work and operate."
"The most valuable features are the basic storage, file management, Btrfs file system, and built-in backups that come with the solution."
"Because of its simplicity and the wide array of features it offers, I would recommend DSM for both tech-savvy individuals and those who prefer a straightforward file-serving solution."
"The solution's most valuable feature stems from its ease of use, making it the tool's most interesting part."
"The most valuable aspect is its ability to handle multiple disks."
"It offers a variety of software options through its package center, allowing users to customize their NAS device to serve multiple purposes."
"The most valuable features of Synology DSM are its security and connectivity."
"The most valuable feature of the solution is that it serves as a backup for our company's virtual machine."
 

Cons

"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 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 backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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."
"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 only bothersome aspect is that the device is aging."
"Even though Synology provides a backup solution, it does not recognize the VM movement across cluster hosts."
"The platform could be much more cost-effective and flexible for integrating third-party products."
"The product's only shortcoming is pricing, as it is an expensive solution."
"There's a surveillance application that allows you to connect IP cameras and stream footage to Synology and it is a great feature, but it's not always clear that adding more cameras may require purchasing additional licenses."
"Synology DSM's user interface is not quite intuitive."
"Users may lose their data if they don't configure the solution properly."
"Synology DSM is a good enough solution for small and medium companies, but I have not seen a big configuration of the solution for a big organization."
