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.

Have supported critical environments despite room for improvement in legacy backup options
It is very efficient in cyber resilience. Deduplication, automation, and everything is very efficient. It is multi-cloud enabled and has broad protections. The software delivers flexible and efficient backup and recovery options through its cyber resiliency features. Dell PowerProtect Manager provides insights in managing backup processes. Its encryption mechanisms are very efficient, helping to secure sensitive data. Its integration with Dell EMC Data Domain is very good. It is easy to integrate with Data Domain. Multi-cloud options are enabled, and backup in cloud options exist in Dell Avamar.

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."
"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."
"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."
"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."
"So far, Avamar covers everything we want, and we are replicating to other sites for disaster recovery, so it's working well for us."
"I have found the product to be scalable."
"This is a great product and the integration is easy with other solutions, like the cloud or Data Domain, and it's scalable."
"If you're enterprise, you are definitely going to use Avamar because it can save a lot of space because of its duplication feature, which is great."
"Avamar's source-side deduplication is very strong, it can easily back up remote sites' data, and not much bandwidth is required on the Avamar side."
"The setup is very easy."
"The most valuable feature for me is the backup functionality; it gives large enterprises the comfort of knowing their workloads are being backed up."
"Client deduplication."
 

Cons

"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."
"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."
"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."
"Adding new nodes is an extremely difficult task. Took me nearly 28 hours for node addition and data rebalance."
"If you want to set up integration with a cloud environment, for example, it's very difficult to do that. Avamar doesn't work very well in the cloud environment."
"Avamar cannot back up Nutanix as a virtual solution."
"It was challenging to back up our Exchange database, which is one of the reasons we did not continue using this solution."
"If there is a need to move the data from one backup solution to another, it might be difficult since there is no option for a straightforward migration."
"The licensing price must be reduced."
"The recovery is a bit slow."
"Some customers need to back up to tape, but Avamar lacks support, so it costs a lot."
 

Pricing and Cost Advice

Information not available
"It might not be beneficial to smaller businesses due to its high cost."
"This is a fairly expensive solution. It cost approximately 21,000 each year."
"It is easy to use."
"There are licensing costs for Dell EMC Avamar and it is paid annually."
"There is a license required for this solution."
"The price is fair."
"Its licensing is weird. It is not just the licenses; we also purchase hardware. With most software products, such as Veeam, Commvault, and Data Protector, there is no hardware purchase at the same time. Because Avamar and Data Domain are tied together, they have an integrated pipe. You can separate them, but basically, they're designed to work as a couple. Because the Data Domain backend is designed to do dedupe and compression, we get 60:1. When you count it, you count it as a straight compression, but of course, that's with dedupe and some other stuff. You have to buy the hardware, the licensing, and the software at the same time. So, it's not just software."
"It is expensive. The maintenance comes with it for five years. So, you buy the whole thing for five years, and your maintenance is included with it, but it's a big chunk of change upfront. We like capital expenses because we can CapEx them. We pay once every five years, so we spend a big chunk of change. You'd have to divide that out by the five years to come up with how much it costs. It's just about three-quarters of a million dollars for five years."
