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.

Quotes from Members

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

Pros

"I am impressed with the tool's technical alliance with Veeam and Veritas."

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

"Zerto is 400 times better."

"We're able to replicate all of our data and be able to bring up an entire data center within a matter of minutes, which has become our go-to for our resiliency within both of our data centers."

"Zerto saved us a lot of money compared to the cost of replicating at the LUN level. It also really simplified it and gave us shorter RTOs and RPOs."

"We own another solution called VMware Site Recovery Manager, SRM. We have licenses for our entire environment and we still decided not to use it. That's how big the difference was in the experience that Zerto provides."

"Implementing this solution has given us sandboxing and the ability to move VMs."

"The recovery speed is much faster and less complicated."

"Zerto's single-click recovery solution offers exceptional recovery speed."

"When we need to failover or move workloads, Zerto significantly decreases both the time it takes and the number of people involved. It only takes a single person to activate a failover and we can pretty much automate everything else."

More Zerto pros

Cons

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

"The product needs to improve performance while scaling out. It also needs to improve stability."

"I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins... as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which."

"If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."

"The solution is very expensive."

"I would like to see a separate product offer for performing backups, although I think that this is something that they are expecting to release in the next version."

"My input would be to have their sales engineers not overpromise and then have the product underdeliver because we were scoped not-appropriately sized target hardware. That hit us hard. We went with Exagrid as our target. Because of incorrect sizing, we didn't get the expected compression, and we ran out of space. We didn't have enough capacity for all of our backups the way we wanted them tiered. It crippled Zerto as well."

"Zerto's price has room for improvement."

"Zerto's current reporting capabilities are insufficient for our needs."

"I would like them to add a VM host replication option. Being able to replicate host configuration between sites would be a huge benefit."

Pricing and Cost Advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."

"Zerto is expensive but offers many features that make it competitive."

"We subscribe to their annual license package and we have tier one support with them."

"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."

"Zerto previously had a perplexing licensing structure, but they have since resolved it by implementing a unified license."

"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."

"At close to $1,000 a license, it makes it very hard to protect all of your environment, especially for a smaller shop."

"You need to figure out how many critical servers and applications you have in your environment so you will know how many Zerto licenses to buy."

"Its pricing is way better than Veeam."
