Zerto Reviews

For all the most important applications, we are using Zerto as a hot site in case something were to go on with our on-prem data center-based applications. We can immediately resort to Zerto as a failover.

It's deployed for replication from our data center into the public cloud.

The most important thing is the mean time to restoration. When anything goes wrong, we should be able to rely on the failover data that is available, and we should be able to restore it as quickly as possible. We have been able to reduce that mean time to restore the data pretty significantly with Zerto. It's gone from a few hours to a few minutes.

There are two things that are keeping us with the solution:

1. It does a very good job of keeping the data in sync at all times. 
2. In the event of a failover or in the event of a contingency, we are able to retrieve the data very quickly without any issues.

Both of these points are valuable to us because we have application data and it means we keep the data in sync. It is very important for us to know exactly where we left off in the event of any disaster or contingency. We can always rely on, or resort to, the data that we have as a backup or a failover. Also, in the event of a contingency, or even for doing a mock contingency exercise, the speed of retrieval of data and the speed of getting back up and running — minimizing the downtime — is important. That's where the second feature comes into play.

There are two areas which I would recommend for improvement. One is when we are trying to upgrade any virtual machines, we have to stop the virtual machines that have been replicated in Zerto and then upgrade or update to the virtual machines onsite. Instead of having to do it manually, there should be some way of automating that particular function.

And when it comes to AWS failover, the documentation has a lot of scope for improvement. It's come a long way since we implemented it, from the scantiness of documentation that was available to do a failover into AWS or recover from AWS, but they could still do a much better job of providing more details, how-to's, tutorials, etc.

In terms of additional features that I would like to see included in the next releases, if they could provide us some kind of long-term storage option, that would be the best thing. Then it could be a storage and a failover solution combined into one.

I have been using Zerto for two-and-a-half years.

It's a very stable solution.

It scales very well, in terms of the data size and the number of sites that we want to add on. It has scaled very well, at least in the last two releases.

We have plans to increase usage, but as it is we are using it for about 75 percent of the data at this point. The balance of the data will come onboard by early next year.

We have about 25 people using Zerto, and they're mostly database and storage administrators, infrastructure people, and security people. 

We have not used the technical support. One thing I can say is that they have a very friendly team of engineers. If you have a problem, they are at your beck and call. You can call them and get it resolved.

We were using another solution but I don't want to name it. The primary reason we switched was the ability to restore the. Our main goal was not only to have good replication of data, but to be able to restore the data as quickly as possible in the event of any contingency, whether planned or unplanned. 

From that standpoint, when we put Zerto against the existing product, what took us a few hours in that product took us a few minutes with Zerto. That was primarily the goal. Even though this product was a little more expensive than what we had prior to going with Zerto, we still went ahead with Zerto.

The initial setup is very straightforward compared to a lot of others. The user interface is very simple and very intuitive. It goes one step at a time so you can logically follow through the steps to set it up. Whether it's a small site or a big site, it doesn't really matter.

Overall our deployment took about two weeks. We had a detailed project plan, as we always do with any new products or projects that we come up with.

It doesn't require any full-time staff to deploy and maintain the solution. Once you turn on the process, all that somebody needs to do is just monitor the schedule and see whether it's doing things the way it has been programmed.

We have absolutely seen return on our investment with Zerto. We do mock disaster recovery exercises and, in every such exercise since we've gone ahead with Zerto, we've been able to restore the data within a few minutes, very easily, without any business loss. That gives us the confidence to say that, even in the case of a real disaster, we should be able to restore the data.

We didn't evaluate any other options.

Know your use case and then do a thorough proof of concept with your use case to see whether the solution works for your environment and your specific use case. Have a well-defined project plan and negotiate your way with the vendor.

The biggest lesson our organization has learned in using Zerto is that you should understand the product very well. You should understand what the product is capable of doing and leverage the options and features that are available in the product to the optimal extent. 

Virtualization, and Zerto improves business continuity and disaster recovery tremendously.

• Continuous replication for VMs
• Ability to choose point in time to recover from
• RPOs in seconds
• RTO in minutes

Adding or changing VPGs (Virtual Protection Groups) may require restarting replication.

The product is very stable; no issues with upgrading to new releases.

Adding additional VMs is fairly easy. Adding or changing VPGs (Virtual Protection Groups) may require restarting replication.

Very good.

Previously we used SRM (Site Recovery Manager). Zerto is much easier to set up and configure. Failover using Zerto is simply a one-button click, and it does everything else in restoring the VMs at a different datacenter (recovery site).

Initial setup is fairly easy and the environment can be protected in just a few hours.

You can find providers of a DRaaS solution with Zerto license fees for each VM. Zerto only sells to partners and they have a robust partner organization.

The product works and does what is says. Zerto provides enterprise-class, virtual replication and BC/DR solutions for private, hybrid, and public clouds. Future releases will provide multiple destinations/locations to store the replicated data.

Most companies have used backup software for their protection, or disk array replication. Zerto leapfrogs those data protection methods and provides a much more affordable BC/DR solution, with improved RPO and RTO.

Zerto is an excellent solution for cloud-based environments, but for DIY clients who have another site to recover their systems it also works well.

The ease of daily operations. This program takes almost no interaction on a daily basis.

Zerto has given us a sense of security. To know that we can move our production data to our DR site in minutes lets me sleep much better at night.

Support for Hyper-V which is on the way.

In production for almost 1 year now.

Absolutely none. I was replicating my first VPG in less than an hour.

Only things that I have caused myself.

Started with 50 vms today protecting almost 300 and I have had no issues.

I would give it an 8/10. Alot of customer service is handled through back and forth emails but once you get someone on a phone call and screen sharing the level goes to a 10/10.

9/10

Alot of customer service is handled through back and forth emails but once you get someone on a phone call and screen sharing the level goes to a 10/10.

We tried out SRM but chose Zerto because of the ease of use.

Very straightforward and I had a tech with me the whole way.

Implemented in-house and once again it was a PAINLESS process.

SRM and went with Zerto so we would not have to use SAN-to-SAN replication.

The best thing is that all you need is storage and vcenter in two locations and you have met all requirements to install and protect your vm's.

We are using Zerto to facilitate cloud adoption in the organization. Our product teams are migrating their VMware workloads to the cloud, and Zerto is helping with that task.

Zerto provides us with continuous data protection and it is working well for us so far. It has matched our requirements, especially in terms of compliance and security considerations. The solutions in our environment are working together to make everything achievable in terms of different certifications.

We have only been using Zerto for less than a year, and have not had much time to consider long-term data retention. However, it is our intention to use this capability in the future.

Using this product has enabled our leaders to guide the business through our transition to the cloud. It has allowed us to implement a cloud-based disaster recovery solution.

Having a cloud-based disaster recovery solution, rather than a physical one, saves us in terms of resources. I don't have exact numbers in terms of money, but I can say that in the short time that we have been using Zerto, it has saved us between 10% and 20% resource-wise, including time.

We do not have any real use cases so far, but our model shows that we will need fewer people involved when we failback or move workloads. I expect that we will require 10% to 20% fewer resources in these situations.

So far, we have not had a use case where we had less downtime because of Zerto.

The most valuable feature for us is accelerating cloud adoption, as it helps provide greater speed for disaster recovery. Ultimately, this saves us time, as well as resources.

This product is easy to use. Initially, we had some issues and hiccups but we worked with the solution engineers and were able to rectify the problems and move forward.

When we initially set up the product, we didn't know about the exact features. Some of them were discussed in different wording. It took some time to get to know the solution in general, and exactly what functions each of the features is used for. They seemed more like hidden features to us.

I have been using Zerto for close to one year.

The availability of Zerto has been good for us, so far. We have not experienced any issues with it.

Being a cloud-based solution, it can be scaled as per our requirements. I don't see any issues with it. We have three people who work with it, although not on a daily basis. They are technical analysts and product engineers.

They were more hands-on during the PoC and deploying it, and they will be involved if we have any issues.

Technical support from Zerto is good and they help us all the time.

The turnaround time is good, as well as the help that they give us in understanding and resolving problems.

We are still using our previous solution for backups. We are switching away from it because we will be able to take advantage of automation and use fewer resources.

In terms of cost, using Zerto saves us approximately 15% over our previous solution.

The initial setup is straightforward. It was easy to set up the PoC and the results were good. Setting it up took a few hours and when it came time to move to production, it was in terms of days.

My team was responsible for deployment.

We have seen a return on our investment in terms of time and resources.

We evaluated several other solutions prior to selecting Zerto.

We chose Zero because it is more user-friendly, and better overall.

My advice for anybody who is considering Zerto is that it's user-friendly, easy to use, and easy to deploy. So far, Zerto has been working fine for us and my team has not had any complaints.

I would rate this solution an eight out of ten.

We use the solution for DR failover/testing on our DR site. We're a Windows/VMware environment and replicate 25 virtual machines from our primary data center to our disaster recovery site. The solution allows us to perform live failovers without shutting down our production systems.

Zerto has made the testing and the actual failover process of our replicated virtual machines seamless. The product has relieved the administrative burden for the IT staff responsible for the disaster recovery implementation of the organization. Adding new virtual machines is quick and easy, and managing the environment is straightforward.  

Failover testing is the most valuable feature. The fact that we are able to test the failover of live systems during regular hours is invaluable to our organization. No longer do we have to schedule failovers of our systems, which brings down our production environment.

There are a couple of minor areas that could use improvement.

The GUI could be streamlined a bit more to enhance the administrative tasks. I would also like to be able to throttle the email alerts, as sometimes they become a bit noisy, and get tough to keep on top of.

Our company has been using the product for four years.

This is a very stable solution.

It is easy to add new licenses for growth.

Support has always been readily available if there were issues.

We never used a different solution.

The initial setup is pretty straightforward and seems to be in line with similar products.

We did not evaluate other products before choosing this solution.

Leveraging 'Move' to perform VC-to-VC migrations with little downtime.

Has simplified our DR/BC strategy and allows us to quickly protect Production applications that require low RPO's. We've done several fail-over tests with documented results. We feel Zert0 will only compliment our SDDC strategy.

POC'd the product for 2 months and purchased in March of 2014.

None.. Implementation was simple and quick. We were replicating vms in a matter of hours.

Nothing to date

No

Customer service has been excellent

Technical support has been exceptional

We've used traditional LUN based replication which can be challenging in any virtual environment. Zert0 gave us the granularity to replicate VMDKs to any target datastore.

Setup was simple and straightforward. We encountered no issues.

We spent weeks doing a POC and literally installed and re-installed multiple times to see if there were any impacts on our infrastructure. There were none and it worked as advertised.

N/A

We had capacity so our only setup costs were building a couple of VMs to install the Zert0 Consoles on and licensing of the product. Minimal when compared to SRM, Recover Point and Storage.

We did a POC with SRM and researched Recover Point extensively.

I feel because the product is so simplistic yet extremely robust and effective management may perceive Zert0 as not being Enterprise worthy when in reality, it is. Bottom line, its a great product that brings standardization and simplicity to DR/BC.

We use Zerto to keep a replica copy of the core servers we have running at our backup site. In the case of an outage, we are able to flip over to our backup location. Zerto keeps these servers up to date within seconds and in the case of an outage at our core data center, we can flip over services with little to no data loss.

Mostly what Zerto gives us is peace of mind. 

We do the normal backups and that data gets stored offsite, but unlike backups, Zerto gives us the ability to be back up and running within minutes on a copy of our servers that is an identical copy of what is no longer accessible.

The features we found most valuable is site-to-site replication. This is what we purchased the product for and what we use it primarily for. We are in the process of switching over our production data center and Zerto has been a true time-saver that has cost us zero downtime.

Some features are not up to what we need, although we have found alternatives and aren't really looking for Zerto to handle those items today.

The setup process is time-consuming.

We have been using Zerto for around four years.

With its built-in notifications and reporting, Zerto will alert you if there is anything wrong before it can become a problem.

Zerto works for one or one thousand machines and scaling out is an easy process. Zerto also seems to better support the major cloud vendors, with updates as well.

Zerto technical support has been very responsive and has always been able to help. They are available 24x7 and always have someone to contact you right away.

Prior to using Zerto, we were using VMware's SRS. It was not keeping a close enough copy of our servers.

The initial setup was very straightforward, but also a lot of information was needed. A fair bit of time was spent setting things up, but it was really just time-consuming. There was nothing that needed to be done by the vendor.

As far as setup and maintenance are concerned, you need to be sure to set it up properly, test it, and occasionally perform updates. For the most part, once it is in place it is pretty hands-off.

We implemented with the help of Zerto, who was very helpful in explaining the process and how everything works.

Zerto is not cheap but is an invaluable asset.

If you have the need for what Zerto can do for you then the cost really isn't a factor.

We only had experience with VMware's product and didn't know of anything other than Zerto. Once we tried the product we were hooked and never had a reason to look at anything else.

When we implemented Zerto, we only utilized some of the features. This was mostly because of our needs at the time and partially because the other parts were not up to what we needed. They have since greatly improved on these parts, like the backups features, but we aren't really looking for Zerto to handle those items today.

We have never regretted implementing Zerto and I would not trade it for any other product.

Our primary use for this solution is DR Replication to a separate data centre. We use VMware at both sites. We're currently replicating around eighty VMs from our primary data centre in London to our secondary data centre in Beccles. Most of these are SQL servers with the VSS agent installed.

We now have the ability to activate replicated VMs at our DR site within minutes of something happening to our primary data centre. The ability to have a RPO of seconds has enabled us to restore data to just before an incident has occurred, which certainly saves a lot of time and money.

The most valuable features of this solution are its ease of use and simple setup.

The ability to do a test failover to an isolated environment has been very useful, as this allows us to test servers without any implications to our live environment.

The dashboard is very clear and concise, showing any problems in different colours.

The VSS agent setup and configuration does seem to be a bit clunky compared to the rest of the software. We have had issues with licensing, where the license we've been given by Zerto support doesn't include VSS replication, which was a pain at the time.
