Backup platform has significantly improved recovery speed and reliability for critical outages
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 use of Datto SIRIS has significantly improved our Recovery Time Objectives. We have been using other software like Veeam and Microsoft Backup as well, so we have found Datto quite competitive to them. Our experience has been good so far, our clients are satisfied, and we have been handling outages effectively. We have not had the opportunity to use the One-Click Disaster Recovery feature because the last time we experienced a phishing attack, it was resolved and did not escalate to a disaster scenario, so we did not need to use that feature. Datto SIRIS improves reliability by providing storage space that enhances overall dependability. The centralized dashboards in the Hero Reports feature have been most beneficial for our IT reporting needs. The Hero Reports feature provides extensive capabilities that include the specific points we need for our demonstration. Even if we want to use these features to train machine learning models, they are very useful for us, and we do not need to perform much work on the data to extract those features. It has helped in reducing disaster recovery testing hours because it has features that help us by monitoring malicious activities throughout the database and notifying us of any fluctuations in normal behavior. Datto SIRIS is good at assessing effectiveness regarding ransomware recovery, and it is competitive in the market. However, the only concern we have been thinking about is its pricing. The pricing of Datto SIRIS is more expensive than Veeam and Microsoft Backup. On the other hand, it provides many more options and much greater feasibility.

Positive impacts seen with improved data security and reliable support
I have six months of experience with the product, and as a consultant, the use cases for NetApp AltaVault mainly stand out for me. Regarding the deduplication feature in the product, I am interested in whether clients are using it. There are different integrations available with NetApp AltaVault, such as AWS, Microsoft Azure, Google Cloud, and I want to understand how they impact data security policies in my case.

Quotes from Members

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

Pros

"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."
"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."
"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 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."
"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."
"It's so easy to work with."
"The deduplication engine. Right now, we're at about 10.5 to 11 times deduplication of our backup data."
"Considering the disaster recovery scenarios, I want to assess NetApp AltaVault's ability to minimize the recovery time objective (RTO) and what positive impact I have seen from the product so far."
"The dashboard is useful for managing data backups."
"You can store backups for a while."
"Most importantly is having that island into that datacenter, and being able to address things in the same console. Thus, it is irrelevant where it's stored."
"The flexibility. Being able to virtualize it, port it wherever I like, test my backups, test my DR capabilities whenever I like without impacting anybody."
"The solution can be used for all Office 365 applications."
 

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."
"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 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."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"There are some bits it could do better. With tighter integration maybe with Veeam, or something like that, it'd be really good."
"It would be nice if the solution was more complete. Many customers are looking for a single solution or silo that they can manage everything from. It would be nice, instead of having different products, if everything a client needed was in one solution."
"The initial installation is difficult for my clients who have it on both on-premises and on cloud."
"The product must provide multi-gate connectivity."
"The solution needs faster indexing."
"More capacity with the basic model of the AltaVault would probably help out."
"What could be helpful is different user base authentication so then maybe we could allow different customers to point to a single appliance and they only see the backups and things that they have."
"It's a good product, but it's becoming outdated and moving to their other primary architecture."
 

Pricing and Cost Advice

Information not available
"You could compare it to a Dell EMC or ECS, and I think it's probably a little less costly than that. Within the marketplace, it's a medium cost."
"The price is a bit high."
"It is a rather expensive program."
"It's quite cost-effective."
"In one use case, and we have several, to run for a particular customer, the price is about $375,000 a year."
"The pricing is not too bad, but could be a little better."
"There is a need to make yearly payments towards the licensing costs attached to the solution, which comes to around 3,000 USD."
