What is our primary use case?
We use it for replication to our disaster recovery sites for the storage we have on-prem. We needed our critical infrastructure and our critical applications backed up. We needed to have something we can restore from when we have an issue.
Our environment is hybrid. We have some of our servers on-prem, some on Azure, and some on AWS.
How has it helped my organization?
With Hyper-V it helps to ensure high availability. Before I started using Vembu, if I wanted to back up my Hyper-V what I would normally do is go to the folder where I have the VM and copy the hard disk, the VM image. With that I would be able to restore easily. With Vembu, with just the click of a button, it does my backup. I've done a series of restores to test what I'm backing up because that's the essence of a backup — to see how it comes back — and it comes out fine. In VMware you don't just copy your image, but for VMware Vembu also does a perfect job.
Vembu has also ensured that the disaster recovery aspect of our business is well taken care of. It is very critical to the business to have a tested backup. Vembu has helped us a lot in that way. We have restored from Vembu backups several times.
It has saved us a lot of money, but it's not quantifiable. If you have an issue that would cost a whole lot of money but you have a proper backup solution so you don't have to spend that money, you just restore. It might have saved us millions, in Nigerian money.
It saves us time because I just schedule the backups the way I want them and that's it. I don't have to worry about my backups. I'm certain that my data has been backed up. It saves a whole lot of man-hours.
What is most valuable?
The backup is very reliable for both VMware and Hyper-V.
In terms of the compression, Vembu's product is quite good compared to what I've seen from other products.
The encryption is okay. That security feature is fine. You have the option of either encrypting the backup or not. I don't use it in all cases, but I will use it if I'm backing up something and it will be taken outside of our environment. For example, if I'm backing up a VM to an external tape drive or hard drive, I will use that option, to give it another level of security.
What needs improvement?
They keep on improving and I can't see anything that they need to add for now.
For how long have I used the solution?
We have been using Vembu for the past four years.
What do I think about the stability of the solution?
This year was the first time I had an issue with it. I don't know how the issue started. I called their support team and they told me what to do. I tried it but I then decided to simply do a fresh installation.
What do I think about the scalability of the solution?
Vembu is very scalable because it gives you everything you could want. Our environment is medium-sized.
We definitely have plans to expand our usage of it. When you get value from a product you love to do more with it.
How are customer service and technical support?
I love Vembu's customer care. If you have any issues or questions, they respond and their response time is quick. Their technical support is good. I would rate it at eight out of 10. I had a conversation with them last night. I sent them an email and they immediately responded.
Which solution did I use previously and why did I switch?
Prior to using Vembu I tried Acronis. That is what we were using before we dropped it for Vembu. The main difference I see between Vembu and the other solutions we've tried is that with Vembu, you don't need anybody to tell you what to do. Once you have done the installation you just look at the user interface — it's very friendly — and you can do things yourself without resorting to help from anybody.
Acronis would time out most of the time. If you have a slight network-connectivity issue, it causes a problem.
I found Vembu by searching online for free backup solutions. I saw a lot of solutions but that is how I started with Vembu, with their free version. I saw that it solved my problems.
How was the initial setup?
To install Vembu, the only thing that takes time is the download. But once you have downloaded it, within 30 minutes you are up and running. You schedule your backups and you go to sleep.
I was the only one involved in the setup.
There are two guys on my team who maintain it. They have administrative rights on Vembu, like me. They also have many other responsibilities besides Vembu. It doesn't take a lot of effort to maintain it. Once you're up and running you just check your backups and the status to make sure that everything is running. And if there is an issue, you check the log to see why you are having that issue.
What about the implementation team?
I did not need a third-party to deploy Vembu. But when I used Acronis, I had to call their support. Acronis has a partner here in Nigeria that I worked with. The fact that I had to work with a partner with Acronis, and I didn't have to with Vembu, is a major difference.
What was our ROI?
The overall return on investment is quite good. It's good for the business. The margin is on the positive side.
What's my experience with pricing, setup cost, and licensing?
The pricing of Vembu could be better. They have a good product, and I know good products cost money, but they need to find a balance.
Which other solutions did I evaluate?
I also looked at Veeam. I used Veeam for a while before Acronis. Veeam is a fantastic product. I think it is one of the best. It is in the same class with Vembu. I went with Vembu because it is very easy to use. It is easy to install. With the click of a button you can manage everything: add a VM and do your backup.
What other advice do I have?
It gives me peace of mind. If your infrastructure backup is up and running and trusted, it gives you peace of mind.
I have recommended it to a number of people.
It's important to note that most backup solutions will tell you that you can download and use their solution for free. But the truth is that that is not the case for almost all of them. After some time, you will have to pay for a license to backup critical sources.
