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.

Offers near-real-time replication for data consistency and continuously introducing new features through upgrades
There are various advantages. First of all, easy to deploy. The only difficult part is the cost factor, licensing. In other ways, the implementation is very, very important. Like, we have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product. Once you configure it, it goes through the rollback, and then Data Guard introduces this snapshot thing. So once the restoration happens, we can go back to the original thing, and we make that a standard. It's a pretty decent and key function for Oracle. So, enterprise organizations go for Oracle only for features like these.

Quotes from Members

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

Pros

"The core functionality is what's beautiful about it."
"It's good for reliability, timing, and simplification. For reliability, it's a logical construction that behaves productively. It's a critical system where timing and coordination are necessary. It also offers simplicity to design and analyze the system by clearly defining the relationship between events and conditions."
"The most important features are the simplicity of recovery and the wider capabilities and feature sets than VMware SRM has."
"The most valuable features in Zerto are ease of use number one and the support that has come from the Zerto team."
"The most valuable feature is Zerto's ability to precopy data to a remote destination prior to the actual live migration period. That saves us a lot of time and has been very helpful. For example, if we had migrations occurring in waves over a period of several weeks with a VPG or VPG setup of approximately 50 VMs, that is multiple gigabytes of data, even terabytes in many cases. Having that data already copied on the evening of the migration saves considerable hours of time. It easily saves us four to six hours a night."
"The features I find most beneficial about Zerto include continuous data protection, easy configuration, and simplified management with a user-friendly interface."
"Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments."
"The most valuable feature is the disaster recovery capabilities. The fact that we can have a clinic across the country backup in as little as 45 minutes is incredible."
"It's a very good solution if you want to protect your data across two data centers, or you have a middle man or many administrators who use these solutions for protecting their data. It's very reliable compared to other solutions that are most often not storage-based."
"The most important feature is that if I want to test the database at the disaster recovery site, I can take a snapshot, test it, and then revert it back to the original state without needing to restore the complete database from the primary data center to the disaster recovery."
"We have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product."
"If you have a problem with your primary site and can't access your primary database, you can continue working with the database that you have as standby on the other site, by changing its role to primary."
"The most valuable feature is the application or promotional code used in the production protocol to transfer data to the secondary database, situated on the DR site."
"Snapshot and Data Guard Manager are awesome features."
"The solution has been stable so far."
"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."
 

Cons

"We're not fully satisfied with the support team."
"They definitely have room for improvement in a couple of areas. One is role-based access control. Right now, they don't have an identity source so they use the identity of the vCenter or the VMM. If they connected to an identity source like Active Directory and allowed for granular roles and permissions, that would be an improvement."
"To improve HPE Zerto Software, I would suggest that the upgrade process is a little bit average and challenging at the moment, rather than necessarily adding features."
"They had a bug recently that has come up and caused some issues. They currently have a bug in their production versions that prevents their product from functioning in some scenarios, and we have hit a few of those scenarios."
"This solution could be improved by being more cloud agnostic."
"I would like Zerto to enhance the continuous backup aspect."
"I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time."
"Zerto could improve its pricing and customer care. I've never used customer care, but I talked to someone who had, and they weren't given the information they needed."
"One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle."
"Oracle could be improved by the ability to manage it on the cloud. This on-premises version is secure and reliable, but I'm sure that they will soon provide a cloud solution that will be even better. In one to two years, we will probably move to the cloud—we have already moved to the cloud with Microsoft Exchange, but our databases are still on-premises. I would prefer managing a cloud version of Oracle."
"The deployment cost is expensive."
"There is an issue with their application on ODG. There were a lot of edits in the logs. Sometimes, we only get a little cue from the Data Guard Broker logs if there's an issue."
"The only difficult part is the cost factor, licensing. Another area of improvement is support."
"The predominant issue lies in the communication link between the secondary and primary databases."
"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"Oracle Data Guard is stable, but you need to keep monitoring the system all the time. You need to keep monitoring the archives."
 

Pricing and Cost Advice

"I know it is per server, but I am not fully aware of the price model. I know for our VDI environment, they are looking at something that is on the lower end and that they can use just for migrations and not so much a disaster recovery."
"If you are an IT person and you think that DR is too expensive then the cloud option from Zerto is good because anyone can afford to use it, as far as getting one or two of their criticals protected."
"They should adjust the pricing because I feel its price is too much. If they reduce the price, there will be more users and customers."
"When they changed their licensing model, pricing might have gotten a little more expensive for some use cases, but it has been pretty straightforward."
"Its pricing is very competitive. As compared to VMware SRM, Zerto has reduced our OPEX cost by at least 30%."
"The licensing model is good. The price is a little bit expensive, but for what customers get on it, it tends to pay for itself. However, if more and more companies start to improve, then Zerto may need to look at their pricing and make it a little better."
"Having backup and DR is somewhat moderately important to us. The problem with us, and a lot of companies, is the issue with on-prem Zerto. It utilizes whatever you have for a SAN. Or, if you are like us, we have a vSAN and that storage is not cheap. So, it is cheaper to have a self-contained backup system that is on its own storage rather than utilizing your data center storage, like your vSAN. While it is somewhat important to have both backup and DR, it is not incredibly important to have both. I know Zero is trying to heavily dip their toes in the water of backup and recovery. Once you see what Zerto can do, I don't think anyone will not take Zerto because they don't necessarily specialize in backup and recovery 100 percent. They do replication so well."
"Zerto is reasonably price for the product that you're getting. We keep on buying more licenses, so it's a good price."
"The licensing cost is significantly high."
"The cost is expensive."
"The cost of the Oracle license will depend on the negotiations with Oracle."
"The pricing is on the higher side."
"It's a cost-effective solution."
"If you want to have everything automated and done smoothly, you have to add additional licenses."
"This is the best solution if you want something similar that's less expensive than Oracle Grid."
"​Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."
