Zerto Reviews

Zerto is used as our go-to disaster recovery failover software for the replication of key systems from our main office to our main data center. We primarily use it to protect VMs.

Being able to offer the level of disaster recovery RPO that we do has been a game-changer. Offering that level of RPO would have taken other methods to accomplish, but this has been straightforward.

It has been compatible with our VMware environments as time has progressed. We started using this in 2013. To make it easy and even more seamless, they spanned a Layer 2 subnet from one site to another using networking strategies. That way, when we fail over a VM or an asset, it does not change IPs at all. It has definitely given us a level of recovery that we would not have been able to accomplish as easily otherwise.

Recovery with Zerto is faster because, in the past, I believe our organization implemented asynchronous replication and used replication methods that were specific for storage. Having synchronous replication and an RPO that is essentially nothing, between sites, has definitely increased our response time. It allows us to immediately fail over seamlessly. It has also reduced RTOs throughout, since the recovery point objective in general is just a second. The smaller our RPO gap, the faster the RTOs we get.

In terms of downtime, there was a particular situation where we had an unexpected double outage of our WAN link. Unbeknownst to us, both of the fiber runs, although they were from the same company, ran through the same place, along the same train tracks where there was maintenance going. We were able immediately to fail over to our secondary site and keep downtime to zero.

That was an outage that I now know, in hindsight, lasted a couple of hours and it was during the peak closing of the US market for trading. It would have cost us millions. It would've been bad if something had gone wrong, since we needed to trade "now, now, now," but would not have been available. Thankfully we were able to trade.

Another benefit is that it allows for automated testing and non-impactful testing with the ability to spawn VMs in a test. We can perform any type of DR and integrity testing at will without impacting our production. I can't really quantify it but I know that DR tests definitely move a lot quicker now. Normally, DR testing would happen over a weekend. And it used to be the case that we would fail over everything immediately. We still have tests where we do live failovers with Zerto, because they really want to say we have done them. But we have averted investing time in monthly and quarterly tests over a weekend because we can present the automated testing that happens by Zerto with that test network. Without that, we would have to do monthly live testing, so it saves us time.

The most valuable feature is its ability to do failovers from one site to another.

It's also very intuitive, simple, and very straightforward. Its layout doesn't seem very complicated. It shows its features upfront. When I first started using it in 2016, I had not heard about the product, but coming to this company and having to take over managing it was not challenging at all. I was able to intuitively start using it. I have not had any issues with the interface. It's a clean interface and that has allowed me to intuitively use and configure it.

The near-synchronous replication is key. That has allowed us to provide the low RPOs that we promise. For key systems, that has been the deciding factor. The other option would have been establishing VMware's native HA approach, where you have to spawn new VMs. It's not as transparent as Zerto, it's more under the woodwork. Zerto's ability to offer that level of synchronicity and immediateness has enabled us to offer that level of SLA for our processes in case of a disaster.

Recently, I started to try to deploy vVols instead of VMFS volumes in my VMware environment and I did encounter an incompatibility. It seems that for Zerto volumes to be protected, there's some sort of limitation with drives having to be either thick-provisioned or thin-provisioned, I forget which. But there's some sort of inherent limitation that causes an incompatibility with vVols and VMware. That has to be overcome somehow. It has to be flexible enough to be able to do its thing.

And for an additional feature, and I'm not sure if this is already in the works, I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins. We have our three main ZVR appliances, each one of them associated with one of the hosts, but as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which. Better management of those ZVR appliances would help, if you have to vMotion them off of something.

If you want to migrate a ZVR appliance from one storage to another, you can't really tell what's what and there are multiple pieces related to this ZVR appliance. I would like to see that cleaned up a little bit with better management features for ZVR appliance maintenance overall.

I've been with the company since May of 2016, so I've been using Zerto for that long—going on seven years. Through the years, I have become a Zerto-Certified administrator because Zerto offers a free course on it.

It's very stable and very hands-off. I have so many other things to do and the last thing I need to be doing is babysitting Zerto, and that's not the case. Thankfully, it's one of those solutions that you set and forget. You pop in every once in a while and make sure the VPGs are still green and thinking. 

The only thing that has happened over the years is that the data store that this thing was on might have run out of space, but that was for other reasons. As long as you keep an eye on it, it will probably always be green and you'll never have to do anything.

I've been able to engage with their support many times over the years and I have not had bad experiences with them. They've always been very efficient and prompt in taking me out of very sticky situations.

Positive

We already have solutions in place for backup, such as Rubric. We used to be a Veeam shop.

I wasn't involved in the initial setup.

We have two environments, one in our main office and the other in a data center. We have virtual protection groups that protect VMs in the main office and we are able to move them from failover to the data center as a DR strategy. That will change in the future when we move all assets that currently exist in our practice office into the data center as its native location. For now, it's office and data center, but in the future it will be data center and data center.

Our Zerto environment is VMware vSphere 7, and ESXi 7. It's mostly Windows VMs but there are some Linux VMs in there. It's a mixture of thick and thin-provisioned drives, all on VMFS data stores. Those are VMs that it protects and that it is able to move from one place to another.

As for maintenance, Zerto is really hands-off. It's just the usual software updates and that's about it. 

I believe the next step is that the recovery ZVMs (Zerto Virtual Managers) will turn into appliances, so they will be full Linux appliances. That will be great because we won't have to patch the Windows box underneath. Once that migration happens, it'll be even easier to manage. The only other thing that I have to do every once in a while is when we have another VM to protect. I edit the VPG and keep moving.

We have seen ROI due to the lack of losses from downtime that has been avoided.

The pricing seems reasonable. It's still within what we consider to be value-add. Currently, we're running 50 licenses. We're probably going to downsize because there have been organizational changes in our environment and we don't protect as many VMs as we used to.

We have not looked to change over since I got here because Zerto has been that good.

We don't really leverage the restore point backup capabilities of Zerto, although we do, in our virtual protection groups, configure it to have at least two hours' worth of restore points since the last RPO. We also haven't ventured toward DR in the cloud, although there will be initiatives in the future, but it's just something we have not done yet. At least for the assets we're covering with Zerto right now, we've limited ourselves to being able to pivot between data centers.

Currently, we are using it to provide DR coverage for key assets, but I am also going to use it to move all these assets from the practice office in downtown Chicago to the data center, which will be its permanent location. I am going to leverage Zerto's move capabilities to relocate those VMs, Windows Servers, and Linux boxes to the data center permanently. And then I'll establish a recovery relationship between data centers.

For the cost of the product, its value-add, and the return on investment, which is twofold, you should definitely consider Zerto. The hands-off approach and stability of the product alone will give additional dividends. Invest in the solution. It's pretty great.

Zerto is a 10 out of 10 for me. It's one of the easiest pieces of software that I have to manage and one of the most reliable over the years.

Zerto is deployed on a VM, and we use it to replicate the database for our POS system in our data center.

Zerto helps us when our server has an emergency. When we needed to get something from a server that had a corrupt file, it saved us from needing to go back to a tape or a backup to use that server. The recovery works better than our backup. I would rate that nine out of a 10.

It works great because we only use it in VMware for our virtual machines. We use Zerto Instead of snapshots. Zerto is a lot quicker than other solutions. It cuts our downtime in half when we need to recover data.

Data replication is the most valuable feature. The near-synchronous replication works in the background, so it does not interfere with the production usage of the server. Zerto is challenging to set up but easy to use. It's not difficult to configure once you see how it works. I'd give it at least eight out of 10 for ease of use.

I've been using Zerto for about a year.

Zerto is highly scalable. Even though we only have it on a couple of servers, we could do all of them if we want to.

Customer support is great. I'd say it is at least a nine. When I have a technical question, it sometimes takes a while for tech support to respond. That's a problem everywhere.

Positive

I've used backup solutions like Veeam in the past, but Zerto seemed like a better, faster solution. We adopted Zerto because of the speed, and because we wanted to do everything in-house. I would rate Zerto eight out of ten for ease of use, but Veeam seven out of 10. 

Setting up Zerto is straightforward, but I needed to call tech support a few times with some basic questions. I handled the setup by myself because I'm in charge of servers and VMware. It doesn't require much maintenance aside from updates. 

It reduces the time and effort needed to get our data. 

I rate Zerto a nine out of ten. When I first installed it, I learned a lot about how it worked and how to integrate it with my storage. I needed to configure our storage to work with this because we do everything in-house. It's crucial to understand how everything works together.

You need to read the installation instructions thoroughly and prepare your VMware environment. I jumped right into it and didn't go through everything. Read everything and watch some videos first to prepare. If I do it again, I will watch the videos a few times to make sure I understand what's required and go from there.

We plan to use Zerto for migrating our external customers from their private data centers to our data center and Zerto's application services or other cloud services.

Zerto has improved our migration capabilities. Before Zerto, we used other applications, but they had some limitations in terms of platform compatibility. With Zerto, we have platform freedom and can migrate any customer to our data center.

The migration capabilities are very good. The platform flexibility allows us to migrate customer resources and virtual machines from any platform, like Hyper-V or VMware, and it's fast and reliable.

We're in the process of a proof of concept. It's been about three or four months.

The stability is strong and reliable. 

It's scalable.

We will provide support with the help of HPE or Arlanje. We are just preparing that model.

The customer service and support are very helpful. Whenever we ask something, they respond very fast and quick. Their technical knowledge is really good.

Positive

Zerto is faster and more reliable. In the POC process, we compared it with other technologies and brands, and Zerto is very nice.

We compared it to Veeam. 

We still use our previous solution. In fact, we are not replacing that solution. We are just enriching our replication products with Zerto.

Zerto is more user-friendly.

It was easy and fast. The point is, it's really easy.

We used a consultant. The experience was very nice. They were very helpful.

It's very new for us, so we don't have that information yet.

We evaluated Acronis, Veeam, and Commvault. We chose Zerto for two reasons. 

• First, our customers want it. They always ask if we do replications with Zerto. 
• Second, we compared it with other products. 

Zerto is user-friendly, fast, and reliable. We wanted to improve our replication cycle. 

It's also platform-free. I can migrate resources from my customers' on-premises data centers, public clouds, and other cloud service providers' data centers to my data center. That's the biggest advantage for us.

Up to now, I would give it an eight out of ten. It's platform-free, which is the most important thing for us. 

It's also easy to use, fast, reliable, and the replication process is really nice.

We're using Zerto to move services between our on-premises data centers and Azure environment.

Zerto has really helped us streamline migrations to new hardware or other data centers.

We use the solution to move servers and VMs between data centers. Thankfully, we don't have to use it a lot for DR. 

I love Zerto's near-synchronous replication. It's better than other applications that we tried. This near-synchronous replication is super important to our organization because we don't want to lose any data.

We're now trying to do disaster recovery (DR) in the cloud with Zerto. We haven't had any real use cases, but we're piloting it. It's pretty important to our organization to have DR in the cloud because we're in a very rural area where we don't have a lot of redundancy. So, it's important to have the scalability of Azure where we don't have it.

We use Zerto to help protect VMs in our environment, which is our primary use case. Our RPOs are pretty short. We can roll over a data center in 30 to 60 minutes if we have to. It's pretty quick, and we could turn everything around.

We looked at VMware's SRM but decided not to go with it.

We chose to use Zerto because the RTOs and RPOs were a lot faster with it.

Compared to other solutions, Zerto is really easy to use, and its interface is really nice. It's really easy to set up the replication groups in Zerto.

We're struggling a little bit now with the appliance migration with version ten.

Zerto could make some small improvements with some of the newer features. You can back up VMs but can't back up individual objects, like email objects, which could be improved.

I have been using Zerto for about seven years.

The solution's stability is very good. We haven't had any stability issues with Zerto.

Zerto can go bigger than our environment, so I think it has good enough scalability.

The solution's technical support is pretty good. Since we haven't had a lot of issues with the tool, we don't really use the support much. The cases we've opened have been resolved quickly by the support team. The support team seems knowledgeable and quick.

I rate the solution's technical support an eight or nine out of ten.

Positive

We have Zerto deployed in our on-premises data centers and for Azure VMware and Azure native so that we can switch between them. The solution's deployment is really easy. You just deploy the main tool and then tie it into your virtual environments.

Zerto's pricing was not that bad. I think it's gone up since we went live and added the cloud options now that we are an enterprise. The solution is expensive, but it's worth the price.

We use both public and private clouds to deploy the solution.

Overall, I rate the solution an eight or nine out of ten.

We use Zerto for disaster recovery. That is our main use for it.

Everybody at the top wants to be able to hear about our disaster recovery timelines. The ability to restore our Practice Management systems several states away in a matter of 45 minutes is phenomenal.

I love the near-synchronous replication of Zerto. We are based out of Alabama but we have our off-site disaster recovery in Colorado. Being able to have data very quickly over in Colorado is phenomenal.

Zerto has enabled us to do disaster recovery in the cloud, rather than in a physical data center. Having DR in the cloud is super important for our organization. That is where our business intelligence center lives. Without that data, we do not make money.

We have used Zerto to help protect VMs in our environment. It has been a huge contributor and has made a world of difference in terms of timelines. It helps spin up our Practice Management systems in a very quick time frame.

The ease of adding additional servers is valuable. We have a portal that we can go into to add those new servers, and then outside of that, the overall time that it took for disaster recovery simulation is also good.

They are doing a lot of great things, but I have heard that Zerto is expensive.

I have been using Zerto for two years.

I would rate it nine out of ten for stability because we had one virtual machine that was not backing up properly, but we did work with support. We got phenomenal support. They helped us fix it.

I like the scalability. Because we are in the acquisition space, we wanted adaptability. As new engineers are coming in and adding more to our data center, they can go through and they can just add it to Zerto. That is a part of their process. 

They are fantastic. I would rate them a ten out of ten.

Positive

We had a different platform previously, and we swapped it with Zerto about two years ago. 

We had Commvault. We were not getting consistent backups. We were not getting consistent disaster recovery. Each of our simulations did not match up, and nothing made sense.

I would rate Zerto a ten out of ten in terms of speed of recovery versus other solutions. 

It was super easy. We did partner with Verinext to come in and help implement it, so the swapover was instantaneous. It was super quick.

Our experience with Verinext was fantastic.

We have seen an ROI. We had an outage in our data center, and we were able to use Zerto to spin up in Colorado to be able to continue to operate, which is multi-million dollars at 450 animal hospitals.

I have heard that it is expensive, but that is not my world.

N-able was a solution we looked at, but it did not fit our needs. We had previously been using Commvault, and then we found Zerto. Our solutions partners were the ones that recommended it to us. After we saw what it was able to do, we made the swap.

If someone is considering Zerto, I would advise them to go ahead and swap to Zerto. I would share my entire experience with it with them and how it has been phenomenal for us.

I would rate Zerto a ten out of ten because of the recovery time.

We implemented Zerto to improve our backup speeds and data recovery time. Zerto is deployed across multiple departments, and around 12 admins and analysts currently use it. 

Zerto has improved my organization in multiple ways, particularly its ability to scale. We have a massive environment that is undergoing cloud development because we are not a very old company, and we needed something that could help us. It's doing its job. Zerto supports multifocal scenarios across the cloud and on-premise.  

The solution has had a positive effect on our RPOs. The time is faster with Zerto. Another benefit is reduced downtime. Compared to what we used before, I'd estimate it reduces downtime by 25 percent. The solution has saved us time in a data recovery situation. I'm unsure how much, but it's a lot of time. Zerto has reduced our DR testing time by about 30 percent. 

Zerto has simplified compliance with industry regulations by including audit logs and official reporting to support regulatory compliance. It has also simplified our workload because it can do so many jobs.

The best feature of Zerto is the fast, automated backup and recovery. The data lift for applications is short, with minimal data loss. Zerto has improved my RTO because we can replicate and easily manage our data, which has positively impacted my company.

Zerto is easy to use if the installation is done properly. Its near-synchronous replication is wonderful, but I'm still learning how to use it. 

Zerto's analytics could be more detailed. The analytics report seems to be more difficult to read. 

I have used Zerto for 19 months.

I rate Zerton nine out of 10 for stability. It's highly stable. 

I rate Zerto seven out of 10 for scalability. 

I rate Zerto support eight out of 10. 

Positive

We previously used Microsoft Azure's backup option. It was a little bit cheaper, but Zerto's recovery is faster. It's a little bit more expensive but much quicker. 

I wasn't part of deploying Zerto, but I believe it was straightforward for them. It required a four-person team and took around two hours. After deployment, we occasionally experience some software bugs that must be investigated. 

We've seen a 10 percent ROI with Zerto compared to what we had before.

I rate Zerto two out of 10 for affordability. The licensing model is somewhat complex. Adding more flexible and less costly options would help.

I rate Zerto nine out of 10. I would recommend Zerto to others. 

We use Zerto for our application data recovery.

Zerto's near-synchronous replication delivers exceptional results. The data at our recovery site is kept nearly identical to production in real-time, minimizing data loss to near zero.

By utilizing Zerto's immutable data copies and adhering to the three-two-one rule, we have established a highly effective recovery strategy.

While Zerto doesn't inherently block unknown threats or attacks, its detailed history logs enable us to revert to a pre-attack state, essentially restoring a clean system.

Our production machine experienced changes that caused the application to crash. To resolve this quickly, we restored the machine to its previous state using a recovery copy located at the recovery site that was made by Zerto. After powering on the restored machine, we changed its IP address, making it accessible again.

Zerto has a positive effect on our RPOs.

It boasts impressive recovery speed. As a customer, all we need to do is power on the machines at the recovery site - that's how simple and fast it is. Even if the recovered state isn't ideal, we can easily rewind to a specific point in time and power up another instance of the machine at that moment.

Zerto makes it easy to migrate data. The total configuration is user-friendly.

While our current RTO is three hours, Zerto can significantly reduce it to just five minutes.

Zerto helps us significantly reduce downtime during hardware failures, software updates, and natural disasters.

While we haven't experienced a ransomware attack, we have a recovery plan in place. If one were to occur, we could quickly restore production to a previous point in time, minimizing downtime and data loss.

Zerto helps us reduce the amount of disaster recovery testing we need to perform, which also allows us to reduce the number of staff required for the testing down to two.

The Zerto application is licensed per VM. However, the amount of data stored on each VM does not affect the licensing cost. Whether we have terabytes or just a few bytes on each VM, the licensing fee remains the same. This means we only pay for the machines we are replicating, which can lead to significant cost savings.

Real-time replication is a valuable feature, ensuring that changes made to the production site are immediately reflected at the recovery site.

Another feature I appreciate in Zerto is its detailed logging. This functionality allows us to easily access past data and reconstruct the machine's state at any given point in time.

We can recover the replicated machine at the recovery site by simply clicking it back up from the replicated machine. This allows us to keep the original machine running while the recovered machine is active. It's also vendor-agnostic, meaning it works with different hardware vendors like HP or NetApp. In other words, Zerto adapts to the specific hardware we have regardless of the vendor.

Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site.

I have been using Zerto for five years.

Zerto is stable.

Zerto is scalable. We just need to add a license and they provide a new key.

The technical support team offers an excellent service. They empower customers by providing comprehensive documentation and guidance, helping them resolve future issues independently.

Positive

The initial deployment was straightforward, and I handled it independently. My only reference was the provided documentation; I required no further assistance.

Zerto's pricing doesn't depend on the number of virtual applications. Even if we have a server with 200 terabytes of data, we'll only pay for protecting that single server, not for the total size of the replicated data. This simplifies our cost structure.

The licensing cost is fair.

I evaluated Veeam and SIM before choosing Zerto. Zerto's interface is much easier to use than the other solutions I tested. Integrating into our environment is also seamless.

I would rate Zerto a ten out of ten.

No maintenance is required.

You can save a lot of time researching solutions by choosing Zerto. It's efficient, easy to deploy, and easy to maintain. Additionally, Zerto offers excellent support, including comprehensive documentation, breach and RCM coverage information, and a knowledgeable customer support team.

We use Zerto for disaster recovery and cloud migration.

The near-synchronous replication is valuable to our organization.

Zerto's immutable data copies three-two-one rule is great.

The ability to block ransomware attacks and help recover our servers is great.

Since we don't have a backup data center, Zerto's cloud disaster recovery is of the utmost importance.

The recovery point objective for our virtual machines is good. We haven't encountered any significant issues. However, there have been some delays due to the substantial volume of data being written to the SQL server.

Migrating data using Zerto is easy.

Our RTO went from three days to a few minutes after implementing Zerto.

In the event of a ransomware attack necessitating data recovery, Zerto would undoubtedly prove invaluable in expediting the process.

Zerto has helped reduce our recovery time from days to minutes.

Zerto has reduced the time our staff spends on data recovery by 25 percent.

The RPO for our SQL server has room for improvement.

On-premises to cloud migration lacks certain features, such as the ability to directly rename virtual machines. In the cloud, renaming resources often requires cumbersome workarounds like cloning and manual renaming.

I have been using Zerto for four years.

Initially, we had stability issues with the older versions but now I would rate the scalability an eight out of ten.

Zerto is scalable.

The level one technical support is slow to respond and we usually need to escalate our issue to get a resolution.

Neutral

We previously used Azure Site Recovery and switched to Zerto because it is more user-friendly with more features.

While the initial deployment presented some challenges and took approximately two weeks to finalize, subsequent deployments have been significantly more streamlined.

In the event of a disaster, we will certainly see a return on investment.

I would rate Zerto an eight out of ten.

Deploying Zerto in the cloud saves us costs on maintaining on-prem hardware.
