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.
Security Architect at a computer software company with 5,001-10,000 employees
Quick and helpful support, straightforward to set up, saves us time and resources
Pros and Cons
- "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."
- "It took some time to get to know the solution in general, and exactly what functions each of the features is used for."
What is our primary use case?
How has it helped my organization?
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.
What is most valuable?
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.
What needs improvement?
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.

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.
Which solution did I use previously and why did I switch?
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.
How was the initial setup?
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.
What about the implementation team?
My team was responsible for deployment.
What was our ROI?
We have seen a return on our investment in terms of time and resources.
Which other solutions did I evaluate?
We evaluated several other solutions prior to selecting Zerto.
We chose Zero because it is more user-friendly, and better overall.

Manager - IT Infrastructure and Resiliency at Asian Paints
A lightweight solution that is easy to configure and has intuitive dashboards
Pros and Cons
- "It has enabled DR protection for virtual appliances with minimal administrator time."
- "It would be helpful if the reports can be generated periodically, on a schedule."
What is our primary use case?
Our primary use case for Zerto was to enable replication at our DR site for virtual appliances and automation of the failover - failback process. This also gets utilized for recovery at our DR site at different timestamps using the journal history.
This solution is very light, with zero-touch deployment and very enhanced dashboards.
How has it helped my organization?
It has enabled DR protection for virtual appliances with minimal administrator time. This solution also provides a backup option at the DR site without any additional cost of licenses. The Dashboards are very intuitive and can be published to the CIO and CTO.
What is most valuable?
We loved the orchestrator, which allows us to specify IPs for our DR site in advance. It also allowed us to pre-configure the boot sequence for a failover test or actual recovery. Backup at the DR site is the icing on the cake. The concept of a journal history and keeping snapshots at intervals of seconds are quite good.
What needs improvement?
Mobile features are there only for visibility and not to take action. We would love to see the ability to perform actions through mobile apps.
It would be helpful if the reports can be generated periodically, on a schedule.
For how long have I used the solution?
Four years.
What do I think about the stability of the solution?
This solution is very stable.
What do I think about the scalability of the solution?
This is a scalable solution that also supports multiple clouds.
Which solution did I use previously and why did I switch?
Our earlier solution doesn't have a detailed orchestrator and didn't support appliances.
How was the initial setup?
It is very easy to set-up this solution.
What about the implementation team?
We implemented this solution in-house, without the need for any partner to assist with the set-up.
What was our ROI?
There is no need to think of ROI as this is a DC-DR solution.
What's my experience with pricing, setup cost, and licensing?
The solution is very cost-effective and very easy to set-up but does not compromise on features. The features are much enhanced compared to any other DC-DR solution.
Which other solutions did I evaluate?
Before choosing this solution we evaluated VMware Replication & Sanovi.
What other advice do I have?
Overall, this solution is quite enhanced compared to other, similar solutions in the market.
I recommend trying this solution.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

Head of IT at TWM SOLICITORS LLP
Helpful mobile monitoring app compliments the powerful DR testing capability
Pros and Cons
- "The ability to fully test your entire environment without actually performing a failover is invaluable."
- "There needs to be more flexibility in the licensing."
What is our primary use case?
Real-time replication for our Disaster Recovery site, which is currently hosted in another on-premise site but will shortly be moving to a Data Center in the Cloud.
I have also used this solution to do point-in-time restores of Exchange mailbox items and to check updates from Microsoft.
How has it helped my organization?
This solution has given us the confidence to know that our complex systems are being backed up off-site in real-time and are testable on demand. This gives me a real sense of ease when speaking to Management about our resilience, and being able to demonstrate it includes everyone in the processes to confirm that.
What is most valuable?
The ability to fully test your entire environment without actually performing a failover is invaluable.
I really appreciate the Mobile app that allows me to monitor, at any time of the day or night, whether the replications are up and running.
Creating Virtual Protection Groups allows us to treat business services as one.
What needs improvement?
There needs to be more flexibility in the licensing. I've mentioned to Zerto Management that I find the licensing at twenty-five VMs to be very restricting to an SME business, and could there be some flexibility here? Businesses like ours constantly change their IT due to the flexibility of Virtualisation and it would be great to get Zerto on board with that same flexibility.
For how long have I used the solution?
We have been using this solution for four years.
What do I think about the stability of the solution?
It has been very stable and gives me minimal problems, especially when compared to other parts of the business network.
What do I think about the scalability of the solution?
I would imagine that the product would not have an upper limit due to its architecture. It seems to cope easily with our own environment of approximately forty VMs.
How are customer service and technical support?
The person I worked with was very friendly and had excellent knowledge of the product and understood the wider implications of the installation.
Which solution did I use previously and why did I switch?
We did not use another solution prior to this one.
How was the initial setup?
The initial setup of this solution is very straightforward. The installation and configuration are incredibly easy for someone who is reasonably familiar with IT Management.
What about the implementation team?
We implemented this solution in-house.
What was our ROI?
We do not consider an ROI analysis to be relevant in this area.
What's my experience with pricing, setup cost, and licensing?
While we find the twenty-five VM license somewhat inflexible, the actual setup costs are minimal as the product is so easy to install.
Which other solutions did I evaluate?
Before choosing this solution we extensively tested the built-in functionality of our EMC VNX SANs but they didn't function to an acceptable standard so we looked to third parties.
After researching the market thoroughly we decided that this was the one to go for.
What other advice do I have?
I'd strongly suggest carrying out a proof of concept if you're looking at this part of your IT solution.

Senior information system analyst at a government with 1,001-5,000 employees
Is easy to setup and use, but technical support and customer service need improvement
Pros and Cons
- "I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute."
- "Customer service and technical support need improvement."
What is our primary use case?
We use it mainly to move the server alarm between vCenter and the physical center.
What is most valuable?
I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute.
In terms of ease of use, Zerto is a lot easier to use in comparison to similar solutions.
We have had no downtime with Zerto.
The speed of our upgrade is a lot easier because, for example, when I put the move fail and there's a pullout from the destination, I can cover with something from the source and pick it up from the source in person. I can copy the tag from the server very fast.
What needs improvement?
Customer service and technical support need improvement.
For how long have I used the solution?
I've been using it for about five years.
How are customer service and support?
Customer service and technical support need improvement, and I would rate technical support a seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
We switched to Zerto because it is easier to use, and the users did not complain.
How was the initial setup?
The initial setup was straightforward. You open the firewall, install it, connect to vCenter, and then do all the steps to install the software.
What other advice do I have?
On a scale from one to ten, I would rate Zerto a seven because of the bad experience I had with technical support.

Hosting Services Engineer at a legal firm with 1,001-5,000 employees
Helped to reduce downtime drastically by 80%
Pros and Cons
- "The replication feature and DR functionality are most valuable. Zerto has many options when a new server is being provisioned."
- "This solution could be improved by including some sort of compression or de-duplication for the same type of files."
What is our primary use case?
We use this solution for replication from our primary data center to the secondary data center.
What is most valuable?
The replication feature and DR functionality are most valuable. Zerto has many options when a new server is provisioned. If the application team would like to use a replication process, DR process, or RPO, Zerto can facilitate this within 15 to 20 minutes.
What needs improvement?
This solution could be improved by including some sort of compression or de-duplication for the same type of files.
For how long have I used the solution?
We have been using this solution for three years.
What do I think about the scalability of the solution?
It can be scalable depending on the licenses which can be quite expensive.
Which solution did I use previously and why did I switch?
We previously used SRM. SRM is as not as good at Zerto. That's the reason we bought the licensed product as opposed to the free product. I'm hoping that Zerto will be used in the future in our company for data replication purposes like SQL data.
How was the initial setup?
The initial setup was very easy. I followed the documentation to set it up myself. The person completing the setup needs to understand the storage layer and the network layer for the backup. Without this understanding, It may be extremely confusing.
When you apply Zerto to your environment, you need to understand your networking settings, storage settings, and your capacity planning. Setting up Zerto took us 15 minutes.
What was our ROI?
We recently bought more licenses and are exploiting the benefits of Zerto so I would say we are seeing a return on investment.
What other advice do I have?
Zerto helped to reduce downtime drastically by 80%. I would advise others to complete a full evaluation process to ensure they get the most out of it.
I would rate this solution an eight out of ten.

Systems Engineer Virtualization at a tech vendor with 5,001-10,000 employees
Reduced our downtime on some critical applications
Pros and Cons
- "I prefer Zerto because it's a little more automated. VMware has more requirements... It's a little more click-and-go versus click-and-monitor..."
- "Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes... A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there."
What is our primary use case?
I've used it for a temporary migration. We had to shut down a data center and we moved some database servers over to a disaster recovery site. We then did the maintenance at the data center and brought them back.
We're using it only for on-prem and we use it to replicate from our onsite data center to a co-location, but there is a fiber connection between the two, so it isn't an internet-based replication.
How has it helped my organization?
In that migration instance we had six terabytes of data that we needed to protect and bring online quickly. We had a replication going and we made the protection group switch and brought the systems back within less than 30 minutes. It reduced our downtime on some critical applications.
If we hadn't used Zerto, we would have had to vMotion them to the other side and that could have taken hours. That could also potentially have been unreliable because there's a timeout period when vMotion works. We used Zerto to be safe.
What is most valuable?
It is pretty simple to use.
What needs improvement?
Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes. We'll do the failover and some preparation activities and then there's a checkbox you need to check to continue and sometimes it's small, in the corner, depending on which screen you're using. A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there.
We also had an issue with a misnamed network. They should make that a little more apparent when it's not available on the destination side. We were able to go all the way through with it, but when we did the recovery, it wasn't available. A pre-check to say, "Hey, it's not available. What network do you want to use?" would be helpful.
For how long have I used the solution?
I have been using Zerto for about a month because I'm new with my current company.
What do I think about the stability of the solution?
The stability has been alright. We have failed over quite a number of machines.
We did have an issue with one failover. It didn't fail over completely. You really don't want to have to contact support in those situations, but we had to. It could have been an issue on our side as opposed to something being wrong with the configuration. I don't know what happened, but they got it working.
How are customer service and support?
We had to call support during that migration because one of the settings wasn't correct. I don't know exactly what went wrong, but we had to create a ticket. Zerto got back to us within an hour, so we were really impressed with the support from them. It was really good. They got us taken care of pretty fast and we were back online during the process, within an hour. They were quick to respond after we submitted the ticket and then they got it fixed. There's not really much more they could have done in that situation.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We use VMware-native as well as Zerto. It's all circumstantial, based on sites. Some sites ended up getting an SRM license, so we have kept them instead of wasting licenses. And some sites use Zerto. Maybe down the road we'll pick one of the products, but for now, we use both.
How was the initial setup?
Zerto was already there when I stepped into the picture. I helped initiate some of the disaster recovery processes. Based on what I saw from the outside, it was easy because it was ready for that situation quickly. It was ready in a business day or less, aside from the replication aspect or the data sync from when you first set up the jobs. But the basic setup to get things going was ready within less than a business day.
What was our ROI?
I would think we have seen return on the investment in Zerto because we use it a decent amount of the time. We have reduced the downtime within the last month because of it as well.
Which other solutions did I evaluate?
We've used SRM from VMware. Personally, I prefer Zerto because it's a little more automated. VMware has more requirements and VMware tools get us stuck sometimes. If the VMware tools aren't working on a virtual machine, it won't replicate over as quickly or start up as quickly because it's waiting for that service. You have to do custom settings to avoid that. Zerto doesn't have that requirement. It's a little more click-and-go versus click-and-monitor and then trace back and see what went wrong.
Zerto is also probably faster because SRM waits for VMware tools to come up and say, "Hey, we're here." That's not a requirement that I know of, with Zerto. Maybe it is. I'm a newer user of the product.
What other advice do I have?
In terms of the number of staff involved in data recovery situations, Zerto hasn't really reduced that. My team generally handles those situations and it's the same number of people, regardless of which product we're using.
Zerto worked and did its job and it was easy to use. My team liked it, and the database administrators, who were the customers in that instance where we did the temporary migration, appreciated it.
I would rate it at eight out 10. Sometimes the interface can be a little tricky. If you're using a disaster recovery application, you're in a stressful situation already. Sometimes there are a lot of confirmations you have to go through just to start the Virtual Protection Group, and then it starts and you have to confirm again a few minutes later. You're stressed out. You're talking via chats with a bunch of people and there were times where that prompt was probably sitting there for minutes, which cost money.
More confirmations upfront and removing that second one later on in the process would be good, or a popup, instead of it being a small checkbox in the corner of the screen, is my recommendation.
Which deployment model are you using for this solution?
On-premises

Works at a financial services firm with 201-500 employees
A solution that is intuitive and easy, has good support, and gives us peace of mind
Pros and Cons
- "It is incredibly granular and I really appreciate that."
- "It would also be nice if they could find a way to make it where one VM does not impact the entire journal history of the VPG."
What is our primary use case?
We use Zerto as a robust failover and replication solution.
Currently we replicate about 50-55 VMs to our DR site. We have run multiple test failovers, and have even done a full-scale, full company REAL failover. Zerto worked flawlessly.
We use Zerto to make sure that our primary Server farm is replicated and protected in case of a failover.
How has it helped my organization?
Zerto gives us peace of mind. It is also extremely easy to use and very intuitive. We don't have to worry about what would happen if our server room were to be damaged or our building destroyed. We always have that big red button available to failover to our DR site which Zerto does flawlessly and easily. We also have peace of mind with their Technical Support, which has always been nothing but stellar for us!
What is most valuable?
I love all the features really.
The fact that the interface is so intuitive is wonderful. The setup and customization of VPGs are great too. They allow you to customize all of the IP information and even the MAC (if you wish) for any and all VMs, allowing you to change the IP or Gateway, or whatever for any VM you might failover.
It is incredibly granular and I really appreciate that. Zerto has also caused us to organize our datastores in a better fashion that makes sense so that they are by priority and not just random.
What needs improvement?
I have brought this up to support before, but it would be really nice to have the option to "roll back" a particular VM to a previous time in the past if it were to become damaged, compromised, or infected. Zerto does not allow this. It's all or nothing, so you must roll back the entire VPG. You cannot roll back a single VM unless that VM is ALONE in a VPG all by itself.
It would also be nice if they could find a way to make it where one VM does not impact the entire journal history of the VPG. I do not understand why a single VM with mass amounts of changes should impact the journal history of the entire VPG. Although this has never caused me problems, it is an annoyance for sure.
For how long have I used the solution?
We have been using this solution for a little over two and a half years.
What do I think about the stability of the solution?
Zerto is literally one of the most stable solutions we have. If we have any kind of bounce, drop, or failure on our fiber line to our DR site, Zerto quickly recovers and catches everything up as soon as the failure is remedied.
What do I think about the scalability of the solution?
It is incredibly scalable and easy to use. I think that's what makes it so valuable and attractive, especially to those who do not have a DR solution.
How are customer service and technical support?
Support is VERY important, and Zerto knocks it out of the park!
Every time I have called Zerto support, the person I have spoken with has been well informed and knew their stuff. Even if they couldn't readily solve my issue, they quickly escalated to someone that could. They are probably the best vendor we deal with in our IT Dept.
Which solution did I use previously and why did I switch?
We had tried other solutions in the past including SRM and RecoverPoint for VMs. I can tell you they all pale in comparison, not only in functionality and user-friendliness but in support as well.
How was the initial setup?
The initial setup is very straightforward.
They assigned us an engineer and we were set up and replicating within two hours.
What about the implementation team?
We used a Zerto engineer, who was assigned by our Zerto sales rep.
What was our ROI?
The ROI with Zerto can't even be measured. The peace of mind we have gotten from knowing that all of our protected VMs are safely replicated with almost live RPOs is something that you can't even quantify.
What's my experience with pricing, setup cost, and licensing?
I would suggest getting a dedicated, well-informed rep. I'm sure they all have great training but always hold your rep accountable. Ask lots of questions because there are no stupid questions.
Which other solutions did I evaluate?
We have evaluated SRM, RecoverPoint for VMs, and other "built-in" Hyperconverged replication solutions.
What other advice do I have?
Zerto is literally the best vendor that we deal with overall as an IT Department. They have always delivered, and have always been top-notch. I highly recommend them to ANYONE, regardless of whether or not they already have a DR solution. Zerto is better.
Which deployment model are you using for this solution?

Sr. Systems Engineer at a legal firm with 1,001-5,000 employees
Fast replication and recovery, and the mobile app is great
Pros and Cons
- "The ability to perform DR testing to ensure data integrity is critical."
- "Increased granularity in how long to keep the journal would be nice."
What is our primary use case?
We primarily use this solution for disaster recovery. The initial sync was from Pure to Compellent, and DR with disparate storage was great. Once we identified our critical servers, vetted the Live and Test Failover, and got the necessary configuration at our DR site, we are now able to perform tests in a safe bubble.
How has it helped my organization?
This solution is an integral part of our DR plan. The data and servers we needed are protected in a group as I need them. Changing or adding servers is easy and fast. The ability to protect resources that are in hurricane zones has been fantastic. Being able to safely perform DR testing remotely has enabled us to meet DR goals that were put in place. The first DR test with everyone in a room was fun, as everyone who hadn't seen it was amazed at how fast a server can come online.
What is most valuable?
The replication has been outstanding, it was three times as fast as initial Compellent replication. The ability to copy new data and protect new servers without a significant delay in getting the data is very valuable.
The ability to perform DR testing to ensure data integrity is critical.
The mobile app is great.
What needs improvement?
Increased granularity in how long to keep the journal would be nice, currently you can only do hourly up to 1 day, after that it is only daily. The ability to test failover for a single VM in a VPG would be beneficial for testing purposes. Currently alerts come from both replication managers at times, creating a lot of alerts; reducing those would be good.
For how long have I used the solution?
We have been using this solution for just under two years.
Which solution did I use previously and why did I switch?
We did not use another solution prior to this one.
How was the initial setup?
Setup is really easy and quick. Make sure that you have your desired networking for replication and testing in place.
What's my experience with pricing, setup cost, and licensing?
You are getting what you pay for, as this is a solution that requires minimal management after it is configured.
Which other solutions did I evaluate?
We did not evaluate other options that are worth noting.
EMC was too expensive and everything else was tied to the storage vendor.
What other advice do I have?
It has been a great purchase, and we have no regrets.
Not much can be improved in this solution as it has performed to what we had hoped and has the features we currently desire.
