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

"Implementing this solution has given us sandboxing and the ability to move VMs."
"The whole package is valuable. The most useful feature for the company is the rapid RTO, which offers a faster return to operations and brings us back online quicker. The last time we had an issue, we recovered within about 36 minutes, which was probably the most valuable thing for us because, previously, it took four to seven days."
"I appreciate the real-time nature of Zerto. It continuously copies data, maintains synchronization, and allows rapid recovery of key systems."
"With Zerto CDP, we can pull to our recovery objective in six seconds."
"Real-time replication is a valuable feature, ensuring that changes made to the production site are immediately reflected at the recovery site."
"Our RTO is quick, and we can recover five to ten terabytes of data within minutes of a failover."
"The continuous replication with a low recovery point objective (RPO) is crucial for us."
"The main valuable features are the fast RPO and RTOs we could achieve and the analytics behind that."
"Another valuable feature is the possibility of backing up the database from the standby database instead of the primary database, to avoid backup process overhead in the primary system."
"Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced."
"The solution is quite stable. We haven't experienced any bugs, glitches, or crashes. We find it to be quite reliable."
"Backup and application continuity are most valuable."
"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"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."
"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 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."
 

Cons

"The only complaint is that if I remove a host from a cluster, it does not like that. If I move and put the host in maintenance mode to fix it, and vRA is down, Zerto does not like it. Zerto should figure out that this host has an issue and it went down. Zerto should then let me upload that vRA information to another vRA."
"There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself."
"I wish they would...develop their PowerShell module to be more robust. So instead of having to rely on the API to actually include a PowerShell command, it would let you create VPGs, delete VPGs, modify VPGs, etc. This would ease the automation effort of deployment and decommissioning and I'd really appreciate that."
"The quoting for the Cyber Vault was probably the stickiest part, as it had to be tailored to our size of company."
"Zerto could add text alerts if there are critical problems and alerts if changes affect our replication."
"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."
"Customer support has always responded well when we have a problem, although that has gotten a little bit less since HPE purchased it."
"The product could benefit from improvements in automation, specifically in the area of failovers."
"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."
"The only difficult part is the cost factor, licensing. Another area of improvement is support."
"The implementation is complex for anyone who's jumping into it without any experience. It's all command-line driven implementations. For some, that's a turn-off."
"The database administration needs improvement. With Oracle, we have a lot of features for administrating data, but it might be too many. It needs to be simplified. It should be automated. Looking at Enterprise Manager, there are too many KPIs in place."
"Sometimes, the technical support team takes time to respond."
"The product could improve its pricing."
"The pricing of the solution is quite high. They should do what they can to bring it down so that it is more reasonable for customers like us."
"It is a rather complex solution, so it could be more user-friendly."
 

Pricing and Cost Advice

"Zerto is a little bit on the higher side in terms of pricing. It would be better if they had a pay-as-you-go package."
"The solution is very cost-effective and very easy to set-up but does not compromise on features."
"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."
"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."
"Everyone knows Zerto is a little on the expensive side, but what else is there on the market that does the same thing?"
"Licensing is based on the number of VMs to replicate. The first thing should be to get the number of VMs to replicate based on your business needs."
"Its price is reasonable. I have not worked with other tools, but as compared to its competitors such as VMware, its price is lower. So, in my opinion, its price is good."
"The pricing seems reasonable. It's still within what we consider to be value-add."
"It's a cost-effective solution."
"The pricing is on the higher side."
"This is the best solution if you want something similar that's less expensive than Oracle Grid."
"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."
"If you want to have everything automated and done smoothly, you have to add additional licenses."
"The cost of the Oracle license will depend on the negotiations with Oracle."
"The licensing cost is significantly high."
"The cost is expensive."
