Has reduced downtime by enabling fast recovery after ransomware incidents
The facility to use Datto SIRIS is a function that I prefer. The user interface of Datto SIRIS is very simple and very user-friendly. The restore is very fast. The alerts that arrive in my email are very complete. Reporting in Datto SIRIS is very efficient. The reporting via email from Datto SIRIS for me, my customer, and my team shows that every single backup is okay or if there is a problem because the snapshot for the server is broken or another problem that I can address systematically. 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 cost for Datto SIRIS is very important. Using Datto SIRIS notably reduces time and introduces high-level security. Datto SIRIS positively impacts my organization by reducing downtime for the restore. The restore with Datto SIRIS is very fast compared to other solutions that I know.

Leverage disaster recovery with reliable support and cost-effective future-proof features
Zerto is straightforward to implement because it only requires the installation of an agent on the VMs designated for migration. A service, typically a VM, must also be deployed at the disaster recovery location. This entire process is simple and can be completed within three days. Zerto's near-synchronous replication occurs every minute, allowing for highly granular recovery points. This means that even if interruptions or malware disruptions occur within that minute, Zerto can restore to the last known good state, effectively recovering the entire setup to the latest backup. This capability ensures high data security and minimizes potential data loss. One of the main benefits of implementing Zerto is its data compression, which significantly reduces the load on our IPsec VPN. Zerto compresses data by 80 percent before transmitting it across the VPN, minimizing the data transferred between geographically dispersed locations. This compression and subsequent decompression at the destination alleviate the strain on the VPN, preventing overload and ensuring efficient data synchronization. Zerto simplifies malware protection by integrating it into its disaster recovery and synchronization features. This comprehensive approach eliminates the need for separate antivirus setups in virtual machines and applications. It streamlines our security measures and removes the need for additional software or solutions, resulting in an excellent return on investment. Zerto's single-click recovery solution offers exceptional recovery speed. Through the user interface, a single click allows for a complete restoration from the most recent backup within two to three minutes, enabling rapid recovery and minimal downtime. Zerto's Recovery Time Objective is excellent. In the past, if a virtual machine crashed, we would recover it from a snapshot, which could take one to two hours. With Zerto, the recovery process takes only five minutes, and users are typically unaware of any disruption. This allows us to restore everything quickly and efficiently. Zerto has significantly reduced our downtime. When malware affects our data, Zerto immediately notifies us and helps us protect other applications, even those not yet implemented with Zerto. By monitoring these applications, we can quickly identify and address any potential malware spread, minimizing downtime across our systems. Zerto significantly reduces downtime and associated costs during disruptions. Our services are unified, so in the event of a disruption without Zerto, even a half-day disruption would necessitate offline procedures. This would lead to increased manpower, service delays, and substantial financial losses due to interrupted admissions and other critical processes. By unifying service processes, Zerto minimizes the impact of outages. Zerto streamlines our disaster recovery testing across multiple locations by enabling efficient failover testing without disrupting live services. Traditionally, DR testing required downtime of critical systems, but Zerto's replication and failover capabilities allow us to test in parallel with live operations. This non-disruptive approach ensures continuous service availability while validating our DR plan, even in scenarios like malware attacks, by creating a separate testing environment that mirrors the live setup. This comprehensive testing provides confidence in our ability to handle real-world incidents effectively. This saves us over 60 percent of the time. Zerto streamlines system administration tasks by automating many processes, thereby reducing the workload for multiple administrators. This allows them to focus on other university services that require attention and effectively reallocate support resources from automated tasks to those requiring more dedicated management. Zerto is used exclusively for our critical services, providing up to a 70 percent improvement in our IT resilience.

Pros

"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."
"Zerto is essential for protecting critical workloads. We don't protect all of our VMs, but some need to be recovered in a timely manner. The recovery time is almost immediate."
"The replication feature where it constantly replicates and sees that data is always in sync is valuable."
"The core functionality is what's beautiful about it."
"Zerto has helped reduce our organization's DR testing to seconds to minutes. We have been able to save probably close to 200 hours a year."
"The most valuable features in Zerto are ease of use number one and the support that has come from the Zerto team."
"It's one of the easiest products out there, as far as managing and using it go. The UI is pretty dead simple."
"When we replicated our data, I turned up the machine, and it was up in seconds. It blew my mind. I could not believe it."
"The Zerto university for training staff is very useful."
 

Cons

"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
"The onboarding was not very good. It felt like, "Now you have Zerto, good luck. Figure out how to use it.""
"Sometimes we require extra storage for Zerto."
"We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking."
"The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited."
"Some of the ability to automate selections and automate VPG creations could be better."
"The pricing could be a little bit lower."
"We had a situation where we had to relicense VMs once they were moved over. We later found out that that feature is built-in, but it's not easy to find. The way it's done is that you have to go to the target site to turn it on. If that were explained a little bit better up front, that would be helpful."
"Automated protection of workloads from one site to another could be improved."
 

Pricing and Cost Advice

Information not available
"Obviously, I wish it were cheaper and more affordable. But I get what I pay for, so I can't complain."
"It's very reasonably priced. It's a little more than $3,000 annually. That works out to about $20 per server per month."
"Licensing is VM based so you can buy packages or single VM. Price is not low but the power of application is high, so you will get your money back."
"I would like to see different service levels. They're good, but it still takes a lot of our budget in ops."
"The licensing cost is fair."
"My understanding is that it's expensive but worth the price."
"The licensing is a little bit steep, but there is some value that you do get for it as well."
"While we find the twenty-five VM license somewhat inflexible, the actual setup costs are minimal as the product is so easy to install."
