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.

Near-zero downtime has protected critical workloads and now simplifies hybrid cloud recovery
The best features of HPE Zerto Software are mainly very sophisticated and relevant to the current market. The data protection CDP part has real-time replication, unlike other solutions that have snapshot backups. We can set it up hourly, making it ideal for use with workloads. Another attraction is the near-zero RTO, with automated failover within minutes and one-click failover and failback. Currently, we are using a hybrid cloud solution, and HPE Zerto Software supports multi-cloud environments, making it easy to migrate between on-premises and cloud. Regarding the impact of HPE Zerto Software on our RTOs, we have near-zero RTO, meaning the system must be back online within thirty minutes if we measure the time. It is very quick to recover services. With HPE Zerto Software's near-synchronous replication, we have some CDP protection, so we typically write interceptions along with some asynchronous replication. There is almost real-time replication available.

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."
"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."
"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."
"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."
"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."
"It enables protection of a virtual workload to be done by the app, whether single or multi-tiered, with a boot time scheduler. It is pretty awesome."
"HPE Zerto Software has impacted our RTOs and RPOs positively by providing near-real-time replication and instant recovery, which has definitely reduced our RPOs and RTOs."
"Real-time replication is a valuable feature, ensuring that changes made to the production site are immediately reflected at the recovery site."
"The biggest benefit is the application-consistent disaster recovery functionality."
"It reduced the backup recovery time of our main backup solution by several hours. It's reduced our time because before we have to build a system and restore the data, we install the application and restore the data that took us at least a good 24 hours to do that. And now it's really minutes for us to recover our backup solution."
"The constant replication between the primary and the DR site is valuable. Zerto's near-synchronous replication is excellent."
"Compared to the previous DR replication solution, Zerto has decreased both RPO and RTO significantly."
"Its ease of use is valuable. You do not have to do much to install Zerto or implement Zerto on the infrastructure. It is not very complicated."
 

Cons

"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 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 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."
"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 backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"One thing I would like to see in their roadmap is introducing long-term storage in the cloud such as Azure or AWS. They can make it more seamless."
"I would like to have more granular notifications for jobs and workloads within the applying case application."
"I hope that in the future the product will offer integrated encryption functionalities, so that the VPN setup between protected and protection site can become optional."
"Its initial setup can be better. It looks easy, but if you do not have things in the right place, it is not as easy as it looks. Some of the instructions were not clear. They were a little bit confusing. For example, while setting up SSH initially, it was a little bit unclear if I needed to use a regular credential or some other credential. This was one of the things that was a little fuzzy, and we had to get somebody else involved to help us out."
"The alerting has room for improvement as it is the biggest pain point with the software. It is so bad. It is just general alerting on or off. There are so many emails all the time. You have no control over it, which is terrible. It is the worst part of the entire application. I have voiced this to Zerto hundreds of times for things like feature changes. Apparently, it's coming, but there is nothing concrete as to when you can do it."
"Right now, our production environment runs on-premises, and we have a DR copy of everything that we run in production. However, our development runs on that hardware. In the case of a DR event, we would need to shut down development and bring up our secondary copy of production. We're hoping that Zerto is going to be the tool to help us do that."
"The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up."
"A lot of the wording isn't very clear. If you don't know what you're looking at, it just doesn't make sense when you are setting it up."
 

Pricing and Cost Advice

Information not available
"It's not the cheapest tool, it's expensive. But it's doing a good job."
"Its price can be better, but it is not bad. Most small-scale organizations can afford it, but they can come up with more customer-friendly packages."
"The cost is one of the only drawbacks of Zerto because it's very high, and the overall impact of the solution on our organization is relatively low. This is why we are trying to figure out if another product could fulfill the same role for cheaper."
"Zerto previously had a perplexing licensing structure, but they have since resolved it by implementing a unified license."
"Zerto is a little bit expensive [for our budget] but as far as the value that it provides, it is completely justified by all of the savings."
"At the time I had purchased the product, the pricing was fair and reasonable. Over the years, costs have certainly gone up, which makes it hard for healthcare companies to use the solution."
"It was a little higher. We were in a corporate agreement, and we had a software package that included RP for VM. It is easy to compare pricing when you are already in a corporate agreement. Zerto lost on the pricing scorecard."
"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."
