Zerto Reviews

We use Zerto to replicate to a cloud center.

Zerto saved us a lot of money compared to the cost of replicating at the LUN level. It also really simplified it and gave us shorter RTOs and RPOs.

We got hit with ransomware about three years ago, so we had to do a full recovery with Zerto. The recovery is the best feature.

When you compare the ease of use of Zerto versus that of SAN, Zerto is a lot easier because you can do it at the actual virtual machine level versus doing the whole LUN. In the latter case, in the event of a recovery, you would have to recover the whole LUN and see what's in there. It is a lot easier to do any operation with Zerto.

We were hit with ransomware about three years ago, and the amount of time that it took us to recover from that with Zerto was weeks less than it would've taken us with our previous DR solution.

When you compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions, Zerto is a lot easier and faster because you can choose what to recover and when. In the event of a disaster, for instance, you can recover your most important stuff first.

Zerto certainly reduced the staff involved in a data recovery situation. It's so easy to use that one person can do it all in those events. You won't need a guy from the VMware team and another from the storage team. It's all done at the DM level, so, it's easier to recover without having to involve other teams. With our previous solution, we would have needed three to recover, and I was able to do it all myself with Zerto.

It absolutely helped to reduce our organization's DR testing because it's so fast and easy to test without disrupting anything. We can choose what to test, more critical versus noncritical, and how frequently we want to test. About 75% of that saved time is allocated to value-added tasks.

I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything.

We started using Zerto in mid-2018.

We haven't had any issues with stability. It's always up and running. Whenever there's an issue at the DM level that affects it, it'll give an alert.

It seems like Zerto would be good for a big environment. Ours is small and doesn't really grow a lot; the size stays static. However, having worked with it for a few years I wouldn't be worried to use it in a bigger environment.

Zerto's technical support is good. Whenever we have issues, which is rare, they are fast to respond. When we had our major issue, I had a lot of calls with them, and we had to work around the clock. They did a good job of passing us through every time zone and keeping us engaged with someone. I would rate them a ten out of ten.

Positive

We used the snapshot and replication of our SAN that we used to have. It wasn't necessarily a true DR replication tool, but it would do a snapshot and then put a copy of that snapshot somewhere else. That was our DR plan before switching to Zerto.

The initial setup was really easy and fast. We had it installed in less than an hour, maybe even half an hour. After that, we created our groups. The time for that would depend on how many DMs you have, but it's easy and intuitive.

We had someone from Zerto walk us through the installation and setup. They explained every step as we went through it, and it was excellent.

We certainly have seen an ROI. When we got hit, we saved a lot of money because we were able to recover RBMs. Without Zerto, we would have been in serious trouble. So, it definitely returned the investment many times over.

The pricing is pretty competitive to that of other options out there. When we shopped around, it was in line with the price of other solutions.

We looked at Veeam and Avamar. At that point, Zerto was the only one that did CDP, and that was the reason we went with Zerto.

On a scale from one to ten, I'd rate Zerto a ten.

I primarily use it for disaster recovery backup. Also, whenever we need to move things between our different environments, e.g., moving it to different vCenters and Azure, that is primarily done through Zerto

We are in the process of doing a disaster recovery test soon, and Zerto is at the forefront of that. Zerto is really helping out with this. The bigwigs, who don't know anything about technology, come to us and then we explain Zerto to them. Whenever we simulate failures, Zerto has been able to seamlessly and instantly recover. This really gives our team big brownie points.

The most valuable feature is Instant Recovery. Especially when a server needs to be moved over in a crisis situation, Zerto has been there to help me out in a pinch. It is really fast and responsive. It is always there when you need it most.

It is great for reliability. 

I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time.

I have been at the company for about six months and using Zerto the whole time.

It is pretty stable. The only problem I have is with the vRAs sometimes freezing up. Other than that, it has been pretty stable and reliable. I feel like we can count on it.

It is very scalable. I feel comfortable with it. if we needed to expand in an instant we could.

I have only used our customer support for upgrades, but they have been great and helpful. I would rate them as 10 out of 10.

Positive

If I have networking issues on one vCenter, then I can just Zerto it over to another vCenter. This instantly fixes the problem, saving us time and money. In one case, our phone system was down because we were having a network issue at one of the vCenters. So, I just moved the machine over to the other vCenter through Zerto. It came back online, bringing us back up.

It is way faster than just manually moving VMDKs, etc. It saves hours of time and a significant amount of money.

I can compare Zerto to Rubrik's instant VM recovery from our backups. Zerto is faster. Since Zerto is instant, it is always watching while Rubrik has to take time and restore everything.

The solution is really good. I am super happy with Zerto.

I would rate Zerto as 10 out of 10. They are great.

Disaster Recovery and quick file recovery.  We have used Zerto to recover from Ransomware three times.  Between the attacks we have recovered over 2 million files.  We have never paid a ransome.  Our users were only affected just under two hours with the attacks, majority of the time is actually figuring out in the office which pc actually had the crypto locker program running.

Zerto was able to use an EMC PROD SAN, and a HP DR SAN with no issues or compatibility problems which allowed us to avoid buying expensive hardware for a DR site.

Zerto has allowed us to feel comfortable our data is being replicated, and the data is not corrupted.

Zerto is packed full of useful features. The main feature is easy to manage, you will not need to be in Zerto day to day as it runs flawless.

Zerto has a plugin to integrate seamlessly into VMware VSphere tab.

I would highlight is the fact Zerto was used to migrate all of our VMs from one data center to another data center (two different physical locations) when we upgraded to new hardware. The migration was a breeze.

My second valuable feature is being able to click just a few points in the program to initiate a test vm recovery at our DR location. After testing, all test VMs are deleted along with the data. This is automated, you do not need to interact with deleting VMs.

In Zerto depending on your hardware and internet connection between your production site and DR site you can expect an RPO of 15 seconds.

As of the summer 2016, Zerto just created an extremely fast way to recover files from their journal. Instead of going to our long term backup program and taking a half hour or longer to find a file, Zerto is getting me the file in 4min. This is making my life easier and keeping users happy.

I would like to see Zerto come up with an emergency line for support. Support does get back to you quickly, but when your heart is racing because something happened the calmness of a pro on the other end would be helpful. The reports also need TLC, as I do not really find them helpful.

With these two minor negatives the product and support are great and they get the job done. I am an extremely happy Zerto supporter.

The only issue with stability was when I caused the issue by changing VM settings in the DR site. This was a great test for support, they took care of the issue quickly and got me back up and running.

I consistently see 8-18 seconds RPO. We test DR by adding a file to a server, then 1minute later launching the test failover to a site that is 6 hours (drive time) away. The file will be there in the DR bubble.

We added new VMs with no issues, the only issue to keep in mind is the more VMs you add, the more storage your DR needs.

Customer Service:

Outstanding! Pre-sale we had someone with Zerto actually come to our office and make sure this was the right choice for us. After we went live we had a few calls (initiated by Zerto) making sure we were happy and everything was running smooth. We still get periodic emails checking on us. I have not seen that with other companies.

On the Zerto team, Jennifer and Ciana helping us in our times of need.

Technical Support:

AWESOME!

Tech Support is all initiated by email, but then Zerto will call you if needed. This avoids phone cues. The person I talked to the two times I called in were awesome, they were very knowledgeable. Even though I caused one of the issues that needed fixed by support, they did not treat me with any disrespect even though I caused the issue. The tech did explain how to correctly do the tasks.

We had a very experienced consultant set us up.

My advice for someone thinking about Zerto is to do the trial run that Zerto offers, you will be impressed. If you are looking to get RPO's of 30seconds or less, Zerto can do it. I typically see 8-18 seconds RPO. Needless to say this depends greatly on your WAN link.

I highly recommend going to Boston in 2017 and meeting the staff at Zertocon!

The primary use case for Zerto in my company is to manage disaster recovery.

My organization has experienced the benefits of using the tool, which include the ability to test our disaster recovery quickly.

The most valuable feature of the solution is the constant synchronization, ensuring that we have the most up-to-date information should a disaster occur and we need to handle failovers.

Zerto's near-synchronous replication is why we first acquired the product.

Zerto's overall effect on our RPOs is such that it improves them significantly, and it is the reason why we purchased the product. Rather than having to recover from backup, which is time-consuming, it is available instantly.

If I compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions, Zerto is at least five times faster than other products.

It turns out that my organization has not been using all the capabilities of Zerto and we just found from the session, HPE Discover'24, that the things we were looking for already existed within Zerto. I don't have anything to ask for improvement in Zerto.

I don't want any additional features in the product as I would be busy employing the functionalities I recently found out are available in the solution.

I have been using Zerto for seven years.

The tool is very stable.

The scalability is fine for our company. We are a relatively small organization, but it has done everything we needed.

The solution's technical support has been solid and very good, and we hope it stays that way under HPE.

In our company, we would recover from our backup software, so things depended on whatever backup tool was used at the time.

When it comes to the product's initial setup phase, Zerto's support has been very strong and relatively straightforward.

I have experienced a return on investment from the use of Zerto. The exercises associated with disaster recovery are faster and we are able to save time now in our company.

Fortunately, the tool's pricing and licensing are not a concern for me at the moment. Other teams handle it.

The evaluation of other solutions against Zerto was pretty quick. In our company, after we saw a Zerto in use, we couldn't find anything else like it in the market.

I have used Zerto to protect VMs in our company's environment.

Considering that there is always someplace to go from where our company is currently, I rate the tool a nine out of ten.

I am a system engineer and IT architect. We use Zerto to protect our production -environment and critical applications. Everything is on-prem. We don't do any DR to the cloud. We're protecting around 300 VMs right now.

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 valuable feature is the low RTO that covers our VMs and a secondary data center.

I would like Zerto to add support for VMware's lifecycle manager. 

I have used Zerto for about eight years.

I rate Zerto eight out of 10 for scalability. We have one instance per data center that supports everything that we need, and we haven't had to scale past that.

It's been several years since we've looked at other products. We used VMware SRM in the past, but Zerto is way faster. Zerto is easier to use than other solutions we've tried. 

Zerto is easy to set up. Once you've deployed the appliance and connected it to a  vCenter, your VMs are protected pretty quickly.

Zerto costs us several hundred thousand dollars a year, and we haven't needed to use it in a real DR situation, so it's hard to quantify an ROI. However, based on what we know from testing, it will be a huge benefit in the worst-case scenario. 

Zerto's pricing is pretty competitive. They recently went through a licensing change where you have to buy an enterprise license as an organization. We weren't happy with that just because it forced us to pay for extra features we don't use. We would prefer if we could still have that standard license.

I rate Zerto nine out of 10.

We are primarily using it for migration and data protection. We use it for protection of the VM and data protection. 

It's the easiest way to support DR as it does the conversion for you. After converting, it protects again. If you don't want Azure, you can just go back on-premises, for example. 

We can monitor VMs more easily with Zerto. We can always check if they aren't properly syncing. The migrations are also easy. 

The overall impact on our RPOs has been amazing. The ease of using it is great. Everyone is embracing it in our company.

The ease of use is ten out of ten. It's the easiest to use. 

The speed of recovery is great, especially the failover/failback. It helps our company a lot. 

The most valuable feature is the GUI. It's very simple. 

Setting it up is very easy. 

Everything is automated using scripts. 

The solution saves a lot of time and there is no downtime based on how the product is designed. If there's any downtime, it's only a second or two if we move. 

The near-synchronous replication is great. It just works. I'm a big fan of Zerto.

Right now, the solution is perfect. They shouldn't try to do everything. Zerto is DR and needs to focus on that. Everything works for us. There is nothing to improve. 

They already released the features that we want. We aren't missing any features. 

I've been using it for almost five years now. 

At first, when Zerto was bought by HP, we thought it was just going to be HP. However, Zerto is really working out and the stability is great. I hope they continue what they are doing and refrain from making major changes. 

Zerto scales pretty well. They have a lot of customers. The word of mouth is helping with growth.

It scales well with our environment with the conversion from VM to Azure and vice versa. It's so easy. There's no middle-man involved. It's just Zerto. 

The technical support is hit or miss. If it is a high-priority ticket, you get great Zerto support, however, if you just have a question, they redirect you to their documents. 

Positive

We previously used SRM before Zerto. 

The initial setup was not hard at all. We deployed a VM and had our team open the ports and we were all set. 

It only takes about an hour or two if you have the proper people helping you with the networking. 

We have witnessed a lot of ROI. Being technical, I always ask to make sure management is happy with the product we are trying to use. With the migration feature, it's way better now. We are able to migrate from the old data center without any disruption. That's a big win. 

The pricing is fair. The pricing is very competitive and it works well. You are paying for a product that is easy to use and just works. 

We've evaluated multiple DRs and some VMware products. Zerto was the winner due to the GUI. Also, it just works.

I have colleagues who are doing a POC with Zerto and will begin using it based on my recommendation. 

I'd rate the solution ten out of ten. If I could give it eleven out of ten I would. 

We primarily use the solution for disaster recovery. 

We set up the environment and we're testing right now. We are able to do test recoveries and restalls. Once we have everything set up, we'll try a real failover test. 

The DR - Disaster Recovery - is the main selling point. We have a policy that requires us to have, in case our primary goes down, a failover for our production environment to another site. 

The near-synchronous replication is very good. You can set it to a second. It's important to our company. All of our applications are a part of our production. We need to have uptime. We have an SLA that meets uptime requirements and needs to stay up to maintain our company reputation.

We are also protecting our VMs. 

It's had a positive effect on our RPOs. It's meeting our objectives.

The journal history is only up to 30 days. If it were longer, it would be better and I would have more flexibility.

I've been using the solution for a little over a year. 

The stability is great. It is running well. 

The scalability is not too bad. We upgraded our server and we were able to scale easily. We installed Zerto on our VMware with no problem. We have about 200 VMs and Zerto is protecting about just under 100 of them. 

Technical support is an area I'm not too keen about. My experience is 50/50. Level one support doesn't seem very knowledgeable and I don't get the answers I want. That can delay us sometimes. Hopefully, they will improve. 

Neutral

I was involved in the initial deployment. 

The process is not too bad. The process was pretty straightforward. 

The vendor provided implementation support. 

We have noted an ROI. Compared to others, overall, it made sense to choose Zerto.

They are not cheap. They are more expensive than others. However, they have great features.

We did test other solutions. The speed of recovery in comparison testing was great. That was the reason why we chose Zerto over our competitors. 

We looked at Veeam Orchestrator and Veeam is not as complete in terms of DR. 

The ease of use of Zerto and the interface are easier to understand and use.

I'm not sure which version of the solution we're using. It's around version eight. 

I'd rate the solution eight out of ten overall. 

We use it for failing over our production servers in the event of an emergency so that we have minimal downtime to continue business operations.

We only use it for failover to on-prem. We do not use it for the cloud.

Zerto was one of the first failover solutions that we implemented in the organization, so the benefits are pretty drastic. It is hard to compare it to any other solution out there because we do not have anything to baseline it on, but it certainly increases the confidence of our end users. We are able to react in the event there is an issue. The fact that we are not waiting for hours to restore operations is something that we find valuable.

We protect VMs in our environment with Zerto. We are very happy with the RPO results.

Its ease of use is most valuable. The online documentation is very clear and helpful. We are able to solve a lot of problems on our own without having to contact support.

We learned that we got a new account representative supporting our account. I found this out today. Apparently, this is something that they kicked off at the beginning of this year, but there has been a failure in communication in letting us know who is the proper channel for us to reach out to if we need assistance. 

While going from the major version 9 to 10, they introduced a new requirement for ECE Licensing, which is not something that we knew about at the time of our last renewal. We purchased it for a couple of years, and as far as we knew, we were in support. It was only when we were in the middle of the upgrade and had set up the entire environment and tried to put it up, it asked for a license key that we did not have. We were told by the support team to reach out to our account manager. She has been a bit slow to respond. It just seemed like lip service. The timing kind of worked out because there was a conference as early as that. They have been trying to fix it and communicating about it. I am hopeful it will be resolved, but I just cannot say for sure how soon or how fast they can remediate it.

I have been using Zerto for about two years.

It is stable.

We have not had any issues increasing the number of VMs being protected as long as we have licenses. We have over 100 VMs.

They are responsive, but when things need to be escalated, it is very unclear who is going to be the person to ensure that things are resolved. I would rate them a six out of ten.

Neutral

I was not involved in its deployment.

It is hard to say, but the value is there. At the end of the day, the benefits of having a failover solution outweigh the cost.

I did not participate in the evaluation of other similar solutions.

Overall, I would rate Zerto an eight out of ten. We are interested in the technical abilities that it offers, but we would like to see an improvement on the support side.
