Zerto or Veeam?

As a director working in the field of disaster recovery, I often get asked which backup and replication software is better: Zerto or Veeam.

The short answer is that I highly recommend both. Each has their own unique qualities. Both are consumer friendly, and most people would have to agree that they are competitive in the market. When considering which is best for your business, it’s important to take a hard look at what your needs are to decide the best fit. Below is a quick review of each technology and a comparison of their features.

Round 1 – Veeam

Veeam was created in 2006 with a strong focus on virtual machine data backup and replication. Veeam changed the backup and recovery market with their virtual machine first approach.  While many legacy backup products were trying to retrofit their existing technology to support VMs, Veeam focused solely on them until 2016, when they released an agent to protect physical systems to augment their software.

Veeam uses VM snapshot technology in combination with changed block tracking (CBT) to create a replica of a virtual machine. While the snapshot is being taken, a redo file is created, and all changes made during the replication process are written into this file. Once the replication job is finished, the redo file is merged with the snapshot into a live disk file. The next time the replication job is started, only changes made since the last job will be copied to the replica virtual machine.

Veeam also utilizes backup protection that is optimized to allow for long term data retention, and one of Veeam’s key features is that it performs both backups and replications.

Round 2 – Zerto

In 2009, Zerto was founded and built to provide high availability protection to virtual machines. Zerto’s focus is on instant data recovery, and that has helped them become an industry leader in the field of disaster recovery. Another feature that sets Zerto apart from legacy backup products is simplified user interaction. Zerto, like Veeam, integrates painlessly into both Hyper-V and VMware environments.

Zerto doesn’t use snapshot technology like Veeam. Instead, Zerto deploys small virtual machines on its physical hosts. These Zerto VMs capture the data as it is written to the host and then send a copy of that data to the replication site. This process results in near-synchronous replication, since the data is sent to the DR site at the same time it is written to the production disk array. This replication process is continuous, so the delay between writing data to the host machine and sending it offsite is minimal.

Round 3 – The difference

The main difference between Zerto and Veeam is their recovery point objectives (RPOs). Zerto has a tighter RPO than Veeam due to the method it uses to capture data. However, Veeam has the advantage of being able to more efficiently capture and store data for long-term retention needs. There is also a significant pricing difference, with Veeam being cheaper than Zerto. Both solutions provide best-in-class solutions designed for the recovery of virtual infrastructures in the event of a disaster.

I have worked with many customers who utilize both products in order to meet their high availability needs while also achieving reliable long-term data retention. The recovery time objectives (RTOs) for both solutions are similar; when a VM is replicated it only takes minutes to boot the VM in either case. However, the RPO is a big difference, as Zerto provides in seconds what Veeam often needs a minimum of 15 minutes to accomplish (depending on data links and change rates). Most companies running Veeam replicate their data once a day, while Zerto users continuously replicate theirs.


Both solutions are leaders in the disaster recovery market today, but which one is right for your business depends on your unique requirements. If you already invested in Veeam for backup and your company has low RPO requirements, then Veeam is a nearly free option to use for replication. If you are looking for the fastest RPO on the market for your Virtual Systems, then Zerto is probably the product for you.

To conclude my analysis, there is no right or wrong solution. Both solutions are winners, and what is right for your business truly depends on your RTO/RPO requirements. For some users, the best choice is to use BOTH for added reliability.

Do Not Let Good Replace Great

We get so focused on our daily accomplishments that we often forget to enjoy the small things around us. How many times have you ignored a conversation or an individual in your presence to accomplish something which you believe to be necessary or important? I know I’ve done it plenty of times.

Despite having 3 amazing kids, I often find myself focusing on what needs to be done and not enjoying what is going on around me. One morning last week, my wife took our two little ones to daycare on her way to work, so I was home alone with our 1st grader. We had 45 minutes before the bus would come, and I was thinking about what I could accomplish on my computer for work and what house chores I could knock out before it arrived. Then my son said “Dad, let’s go get breakfast before school.” Immediately I wrote off the idea, “There is too much to do.” I thought. Well, in a persistent way, my son asked the same question again and I listened to him and started thinking about it. The dirty dishes would not mind if I did them later, I was about to spent nearly 9 hours doing work “stuff,” and my son wanted  just 45 minutes of my time. We went and had an enjoyable bagel and cinnamon roll while talking about his school and just enjoyed being together. It was GREAT!

While accomplishing the dishes or laundry or that proposal for work would have been good to do, I would have missed a Great opportunity with my son to have a quiet breakfast with just us. These are the moments that we often overlook in our busy day to day lives. Please take a moment each day to enjoy the Great opportunities that are right in front of you.

Flat Tire? Now What?

If you were to get a flat tire on your ride home from work today, what would you do?  Would you sit on the side of the road and wait for help, would you call a family member or AAA, or would you already be prepared and ready to solve the issue? The key factor is preparation.

When is the last time you checked the air in your spare tire or looked to make sure all of the pieces of the jack are there?  Do you know where to put the jack on the car?  If you have not prepared, you will have a difficult time handling this flat tire on your own.

The flat tire is a simple example of how lack of preparation can dramatically affect your life. Recently, a friend of mine was on a business trip. He was running late to a customer meeting and racing down the freeway in his rental car when the tire blew. Because he was running late, he didn’t even think to check the trunk of the rental car for a spare tire or jack. As a result, he found himself on the side of the freeway in a suit in mid-July with a flat tire. He assumed he would be able to change the tire, so he popped the trunk and began to locate the necessary tools, but the wrench for the lug nuts was nowhere to be found.

Not only did he miss his meeting, but he was soaked in sweat and lost an entire day due to a simple problem that could have been resolved easily with the right equipment. Now let’s be honest, nobody checks a rental car for the spare tire and jack—nobody! But maybe we should. This is an example of how our modern society has become so accepting of potential risk and does little to prepare for it. Remember when you (or your parents) would check the oil in the car? When is the last time you did that? While newer cars notify you when to change the oil, they don’t always warn you when you are running low on oil and potentially damaging your car’s engine.

Our lives are filled with constant activities, and we are always moving from one task, project, errand, practice, or event to the next. Oftentimes we put ourselves at risk of major issues that could be avoided with just five minutes of simple preparation. With that being said, I challenge everyone to slow down for five minutes per week to do something proactive in order to prevent a future disaster. These simple details may seem insignificant, but they could have major impacts on our plans.

The tire analogy is merely one of many examples of how we can minimize potential inconveniences in our lives. We might need to slow down and work on a personal or professional relationship. We might need to reevaluate our finances and check our budget before making a purchase. We might need to monitor our children more closely and advise them to make smart choices. The list really is endless, but we all have one area in our lives that requires more focus. Please take the time to evaluate your current situation and prepare for an emergency. It might change your life.

Cloud Forecast: Thunderstorms

If you are in IT, you have heard all about the CLOUD.  What is the Cloud? What does it mean? Is it just the next marketing word for outsourcing?

I have been in IT for nearly 20 years, and nothing has taken over the market like the cloud has. Everywhere I turn, it’s “Cloud this and Cloud that,” whether it is production in the Cloud or DR in the Cloud. While production in the Cloud has undeniable value, I will focus on Disaster Recovery in the Cloud for the purposes of this blog.

When we talk about DR in the Cloud, there are two very different options. First, let’s clarify what the Cloud means—at least to me. Managing your IT in the Cloud simply means that you are allowing a service provider to allocate IT resources to you on an OPEX pricing model with your data, systems, and applications running on hardware that they own and store in their data center. Your responsibility typically starts above the hardware layer. You could call it “Infrastructure on Demand,” but the “Cloud” is way cooler when it comes to marketing.

DR in the Cloud starts with getting your backup data copied off site, but the key differentiator is what you do with that data in the Cloud at the time of recovery. Most of the major Cloud providers limit your DR services to storing your data off site. While this makes sense for data protection, it is severely lacking in recovery capability. Loading your data into the Cloud is simple and relatively easy to maintain—just send a little bit of change data every day. However, the recovery process is far more complex.

With TBs of data in production and off site in the Cloud, and only a WAN connection for access to this data, what will your full environment recovery look like? If you experience a disaster and have to rely on a WAN connection between your DR data repository and your DR recovery site, you will have some serious explaining to do.  This recovery time will be days or months, neither of which is typically within an organization’s acceptable Recovery Time Objectives.

In order to minimize recovery time, you need a DR Cloud Provider that offers system hardware at the same location as your off-site backup data. This will lead to LAN speed recovery and a recovery time of merely hours or even minutes.

When you are considering DR in the Cloud, be sure you are looking for a DR Cloud Provider that offers off-site storage and systems for data recovery. These systems are critical to recovery; not having a reliable backup plan is analogous to driving your car without a spare tire. Ultimately, the best and only way to truly validate your DR in the Cloud solution is to perform a DR test.

Make sure you understand all of the details of your company’s intentions to move to the Cloud, and find a trusted advisor in the market to help craft the right solution for you. All too often, senior leadership gets caught up in the latest marketing buzz without truly understanding the technical details and implications. Get the right forecast for your business!
