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.

An all-in-one and cost-efficient solution that does what it promises
Zerto is very easy to use. Installation is about half an hour, and then it starts protecting the data and VMs. It is not very cumbersome. The UI is built very well. It is fairly self-explanatory. To be able to stand up a product you have never seen in half an hour and get it functioning and protecting speaks to how good the UI and workflow are. Zerto has near-synchronous replication. As a change is made on site A, it gets copied across the network to site B. We are five or six seconds behind production. If I have a heavily used system and I use traditional backups, I could be anywhere from 5 minutes to 23 hours behind. With Zerto, I am single-digit seconds behind. That works well for us. Our disaster recovery test, which used to span an entire week, now takes two days. We used to recover our servers in the first two or three days with a backup product and then test for two days before tearing it all down. Now, we spend half a day on new servers and ensuring things work with networking, etc. We test the next day, and we are done in two days. Across the entire company, we are able to save significant man-hours by shortening the test from a week to two days. We are now doing smaller tests once a month and larger tests once a year. Zerto has reduced our DR testing time by 60% to 70%. We are also able to do more disaster recovery testing. Previously, we were doing it once a year, whereas now, we are doing smaller tests once a month and our large tests once a year. In recovery point objectives, we are single-digit seconds behind. In terms of RTOs, I can recover 350 VMs in 30 minutes. It takes less than several seconds to restore a single VM. From days to 30 minutes for 350 compared to 100 VMs is an incredible time-saving in terms of RTOs and RPOs for us.

Quotes from Members

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

Pros

"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."
"Datto SIRIS has positively impacted my organization by drastically reducing downtime, with recovery from server failures now taking just five to ten minutes."
"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 effectiveness of Datto SIRIS in ransomware recovery is fantastic; I would say it's the best, hands down."
"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 works out of the box and it is a key feature that we really appreciate."
"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."
"Previously, three hours were spent on troubleshooting and everything, but now with Datto SIRIS, issues are resolved in half an hour or less."
"HPE Zerto Software has improved our RPO and RTO."
"HPE Zerto Software's recovery speed to other disaster recovery solutions shows that it's superior."
"One of the features I appreciate the most about the HPE Zerto Software is the simplicity of the replication, which allows the RPO to be in seconds rather than hours, which is what we were used to."
"If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day."
"It's the easiest to use."
"Zerto's two main features are ease of management and that the product just works. It does what they say it'll do."
"The features of HPE Zerto Software that I prefer the most are the backup and the vault. It helps with business continuity."
"I like the granularity of the checkpoints."
 

Cons

"I have not seen any reduction in disaster recovery testing hours from Datto SIRIS."
"The cost is higher compared to other platforms in the market like Veeam or Acronis."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"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 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."
"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."
"It would be great if Zerto could automate replication more."
"There needs to be more flexibility in the licensing."
"The HPE Zerto Software can be improved with more visibility."
"The native Zerto implementation requires quite a big environment. My environment is rather small. I do not have hundreds of virtual machines."
"I definitely would like to see the continuation of the migration capability to Hyper-V included in the next release of HPE Zerto Software, as well as adding migration capabilities to other hypervisors, such as Nutanix Acropolis."
"There should be more comprehensive cyber recovery capabilities."
"There can be a bit more logging. It seems a bit harder to find logs for test restores and all that. If they had a way to email the results of a test restore, that would be excellent."
"The setup process is time-consuming."
 

Pricing and Cost Advice

Information not available
"I would like to see different service levels. They're good, but it still takes a lot of our budget in ops."
"There may be less expensive solutions on the market but with Zerto, you get what you pay for."
"Pricing is adequate at the standard of the product, but there could be "always" some improvement. We would like to see a consumption model that would charge in a DR scenario, where you're failing over and consuming those resources, instead of a per-protected-node model."
"It's fair. My biggest gripe with Zerto is the initial scoping. What we were promised didn't work with what we ended up with."
"The pricing for this solution is reasonable."
"The solution is very cost-effective and very easy to set-up but does not compromise on features."
"Zerto is not overly expensive. It's worth what we're getting for it, but with tough times, a discount would be beneficial."
"I do not have anything to compare it to. It is expensive, but I am not going to squabble about the price when I bring the system up in a disaster. It is what it is."
