Has supported secure data storage with incremental backups and centralized monitoring
Azure Backup supports all the features that we need, so additional features are not an immediate need for me. The documentation for Azure Backup seems okay for me; it is good overall, but it should be more descriptive for each item. It should elaborate more on how backup and restore are fulfilled in different scenarios. One of the reviews indicates that Azure Backup needs improvements for specific backup options beyond just full VM snapshots. I believe it should be improved actually. Regarding specific backup options, I say there should be improvements compared to how they provided them in older days.

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 most valuable feature is the ease in which it backs up our data."
"The fact that Azure Backup is integrated is one of its biggest advantages."
"I like that it's a stable solution and their support is good. I think Microsoft's commercial force is superior."
"It's useful, it works, and it's fairly reliable."
"I have no issues with the stability at all. So I don't necessarily care about the stability of the product. I look more at whether or not can I recover. And I haven't had a failed recovery yet. I've got no failed recoveries of all my years."
"This solution is easy to configure and restore. It is a Microsoft product so is easily compatible with other solutions."
"With a couple of buttons, we can configure a VM for a backup and use the wall service, the storage wall service, pretty seamlessly."
"The setup of Azure Backup is very easy."
"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."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"The effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"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."
"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."
 

Cons

"I would like to have the option to increase the frequency of the backups. Azure Backup does backups on an hourly basis, but I would prefer it to take backups more often."
"I would like to see better integration with more products, and more services."
"We have a concern with the backup when were are working with VMs that are running in Barracuda Firewall because it usually fails."
"Ransomware protection is missing in Azure Backup."
"Technical support can be slow to respond at times."
"It can be further improved by continuously meeting its compliance requirements."
"Azure Backup's licensing model is very challenging because it doesn't give a clear picture."
"My company faces a lot of difficulties in restoring any encrypted VM backup."
"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."
"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"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."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
 

Pricing and Cost Advice

"We are paying about $100,000 USD per year, just for a couple of servers."
"We have enterprise-level pricing. I rate the pricing a five out of ten."
"Licensing fees are paid on a monthly basis."
"Azure Backup is a moderately priced solution."
"We do not have any additional costs for Azure Backup."
"The product is not expensive."
"There is a cost per terabyte for using this solution."
"The price is pretty good, maybe $30 for a machine, I can't complain."
