Makes data protection and network management much easier
The initial setup is straightforward, provided you know the source, target, data version and format. You need to consider all those things. First and foremost, when deploying Oracle Data Guard, the number one priority is to ensure all parameters are correctly set. Two primary methods exist: using backups or recovering from services if the network is reliable. If the network is robust, backups from the source to the target may not be necessary. You must ensure that NIS names are correctly configured on both sides and that the failover and switchover processes are tested successfully from both production and standby environments. Once these steps are completed, the deployment process becomes straightforward. There's no need to copy the entire parameter file; only specific configurations, such as the SID or file structure, must be adjusted if necessary. Ensuring proper DNS name resolution, SID configurations, parameter settings, and understanding whether to convert the Data Guard are essential. Once these aspects are identified, the deployment process becomes more straightforward. I have implemented numerous Data Guard setups. Setting up Oracle Data Guard is performed within the Oracle CRS. Challenges may arise in establishing connectivity between the standby and production databases, necessitating troubleshooting. Apart from that, once configured within CRS, the setup is complete. The challenge with Oracle Data Guard is that it often takes some time for us to identify whether the issues stem from the disk or the network. If we report issues to the network or storage teams from the database end, we may not perceive any apparent problems, which can lead to confusion. We can convince the storage teams to investigate further until we delve into the disk I/O Guard and determine if specific disks operate at total capacity. When disks are operating at total capacity, it can significantly impact application processes. These difficulties in pinpointing the source of issues contribute to the challenges of maintaining and managing Oracle Data Guard.

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

"Backup and application continuity are most valuable."
"The solution can scale as needed."
"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."
"The solution has been stable so far."
"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."
"One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"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 work a lot with customers that need disaster recovery and the best possible migration approaches, and Zerto helps them minimize the amount of effort it takes to finish their upgrades or migrations."
"Since the log files are continuously transmitted, the granularity of restores is amazing."
"We now have the ability to replicate critical data to a secure, off-site location that can be brought back in seconds if needed."
"The journaling is the most valuable aspect of the solution."
"The product is superior compared to the other vendors."
"The ability to test that my backup regime is actually doing and working as I want it to do is valuable."
"I've been fortunate enough not to need to rely on Zerto in an actual disaster, but we do testing every year. Sometimes, it's multiple times annually or at the year's end. It takes the recovery workflow, which would normally take a lot of planning, and reduces that to just a few minutes."
"The most important features are the simplicity of recovery and the wider capabilities and feature sets than VMware SRM has."
 

Cons

"It is a very useful administrative IT tool. It saves on costs."
"Oracle Data Guard is stable, but you need to keep monitoring the system all the time. You need to keep monitoring the archives."
"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"The usage of block storage devices in the cloud or migration of a type of storage from one site to another site can be improved. Currently, we have to use multi-node to single node because of the lack of storage support on the Azure side. It did not really work. Our DBA had to spend a lot of time tweaking the Data Guard tools, or the underlying Oracle VMs, to make sure that Data Guard would run on top of different types of storage. So, if it can support transporting or getting from one type of storage to another type of storage in a different site or a different technology, it would be very helpful."
"The deployment cost is expensive."
"They may need to include the monitoring and the alerting part in Data Guard."
"The predominant issue lies in the communication link between the secondary and primary databases."
"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."
"It is difficult to manage failing over between sites if you are at the site that was impacted."
"Zerto could be considered as a backup product but this is not true. So if we could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where we need to recover something, that would be helpful. Anyway, we think that Zerto will win with no competition in the Disaster Recovery process, so we stay focused on this. Now we are testing version 10 which include real-time ransomware detection, a new Cyber Resilience Vault and enhanced cloud capabilities and security: we expect more from these features for superior hybrid cloud security."
"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."
"We encountered some issues during Active Directory recovery."
"If I had to pick anything, it would be the documentation for upgrades. They need to make it easier for users to do upgrades without having to contact support, by providing better documentation for that."
"My only business complaint is the cost of the solution. I feel like the cost could be a tad lower, but we are willing to pay extra to get the Premium service."
"The backup end of this solution could be improved. We tried using it as a full backup solution and it took way too long to complete at least one backup."
"When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate... It was a bug and they were working on it."
 

Pricing and Cost Advice

"The cost is expensive."
"The licensing cost is significantly high."
"The pricing is on the higher side."
"It's a cost-effective solution."
"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."
"​Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."
"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."
"I wish it were cheaper, but I would purchase it again at the same price."
"We subscribe to their annual license package and we have tier one support with them."
"Licensing Zerto was very simple. They had a product that fit our size and scale. It made it really easy to choose."
"Zerto's pricing is competitive, given the benefits and ease of setting it up. It may seem more expensive upfront, but you're going to save that over the long term by spending less engineering time configuring, reconfiguring, etc."
"It is cost-efficient because we have perpetual licenses. We are a small to medium-sized business, so cost is a pretty big important factor."
"Zerto is slightly expensive, but we do see the value in it."
"It's not the cheapest tool, it's expensive. But it's doing a good job."
"Zerto is more expensive than competitors, making the price difference pretty high. While it is very expensive, it's very powerful and good at what it does. The cost is why we are not leveraging it for everything in the organization. If it was dirt cheap, we would have LTR and DR on everything because it would just make sense to use it."
