The solution can be used to back up servers and Hyper-V cluster nodes, but its support is super expensive
I wouldn't rate Unitrends a ten out of ten because we had some hard drive failures in the appliance. Typically, when you have OneDrive, you can get it replaced. For some particular reason, the situation caused the entire system to crash. We had to reinstall the CentOS operating system on it, and we lost all our backups. They said there was no way to retain it, and it was pretty devastating and concerning that a drive failure would cause the loss of all the data on the appliance. It was extremely disappointing, and we had to start from scratch after three years worth of backup data. I rate Unitrends a nine out of ten for stability.

Leverage disaster recovery with reliable support and cost-effective future-proof features
Zerto is straightforward to implement because it only requires the installation of an agent on the VMs designated for migration. A service, typically a VM, must also be deployed at the disaster recovery location. This entire process is simple and can be completed within three days. Zerto's near-synchronous replication occurs every minute, allowing for highly granular recovery points. This means that even if interruptions or malware disruptions occur within that minute, Zerto can restore to the last known good state, effectively recovering the entire setup to the latest backup. This capability ensures high data security and minimizes potential data loss. One of the main benefits of implementing Zerto is its data compression, which significantly reduces the load on our IPsec VPN. Zerto compresses data by 80 percent before transmitting it across the VPN, minimizing the data transferred between geographically dispersed locations. This compression and subsequent decompression at the destination alleviate the strain on the VPN, preventing overload and ensuring efficient data synchronization. Zerto simplifies malware protection by integrating it into its disaster recovery and synchronization features. This comprehensive approach eliminates the need for separate antivirus setups in virtual machines and applications. It streamlines our security measures and removes the need for additional software or solutions, resulting in an excellent return on investment. Zerto's single-click recovery solution offers exceptional recovery speed. Through the user interface, a single click allows for a complete restoration from the most recent backup within two to three minutes, enabling rapid recovery and minimal downtime. Zerto's Recovery Time Objective is excellent. In the past, if a virtual machine crashed, we would recover it from a snapshot, which could take one to two hours. With Zerto, the recovery process takes only five minutes, and users are typically unaware of any disruption. This allows us to restore everything quickly and efficiently. Zerto has significantly reduced our downtime. When malware affects our data, Zerto immediately notifies us and helps us protect other applications, even those not yet implemented with Zerto. By monitoring these applications, we can quickly identify and address any potential malware spread, minimizing downtime across our systems. Zerto significantly reduces downtime and associated costs during disruptions. Our services are unified, so in the event of a disruption without Zerto, even a half-day disruption would necessitate offline procedures. This would lead to increased manpower, service delays, and substantial financial losses due to interrupted admissions and other critical processes. By unifying service processes, Zerto minimizes the impact of outages. Zerto streamlines our disaster recovery testing across multiple locations by enabling efficient failover testing without disrupting live services. Traditionally, DR testing required downtime of critical systems, but Zerto's replication and failover capabilities allow us to test in parallel with live operations. This non-disruptive approach ensures continuous service availability while validating our DR plan, even in scenarios like malware attacks, by creating a separate testing environment that mirrors the live setup. This comprehensive testing provides confidence in our ability to handle real-world incidents effectively. This saves us over 60 percent of the time. Zerto streamlines system administration tasks by automating many processes, thereby reducing the workload for multiple administrators. This allows them to focus on other university services that require attention and effectively reallocate support resources from automated tasks to those requiring more dedicated management. Zerto is used exclusively for our critical services, providing up to a 70 percent improvement in our IT resilience.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like the fact that you can recover the VMs inside the appliance. For example, they're basically running this appliance on a Linux-based distribution, and they're spinning off KVM virtual machines inside."
"Iinstant recovery (allows a spin-up of your image as a VM on the appliance)."
"They have great support."
"When I have had to use tech support, they've been very good."
"Backup/archive to multiple locations."
"The simple and fast restore routine."
"The predictive analytics are great and the reporting is awesome."
"If you are a large organization, this is a product for you."
"Zerto also improves application availability as our business continues to increase our lifespan."
"Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done."
"Zerto stands out for its user-friendly approach to data protection and recovery, allowing for quick and efficient backups and restores."
"The replication being log-based is awesome."
"The RTO and RPO are unparalleled. In the event you do have an issue, you can be back up and running (depending on the size of your infrastructure) within minutes. Your RTO can be 15 minutes and data loss be five minutes. I don't think that's matched by anybody else in the field."
"Zerto's user-friendliness is valuable."
"I appreciate the real-time nature of Zerto. It continuously copies data, maintains synchronization, and allows rapid recovery of key systems."
"Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."
 

Cons

"The ability to run just differentials without pulling the full on your archive."
"Techs don't see to be well-versed in troubleshooting issues that arise and tickets stay opened for weeks for resolution."
"I would like to see the real-time replication process improved, and a zero RPO feature added."
"Network-based storage stability could be improved."
"The amount of updates which are being released. Updates should be limited to two or three a year, focusing more on quality instead of a rushed bug release."
"In terms of improvement, the UI, especially in the recovery section, is unclear about which repository it uses."
"The solution’s support and onboarding process needs to be improved."
"Support is great for small simple issues, but anything more difficult, it is hard to get good resolutions without having to badger them and their management."
"There is a need to allow the source vCenter Inventory to be imported with a single click."
"We would like the LTR function to be able to retain the past 12 months."
"The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me."
"Their offsite backup is a bit clunky, but it will probably improve."
"The email alerts can be excessive, so better control over frequency or resolution may be a worthwhile improvement."
"I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react... Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention."
"I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology."
"We have had issues with licensing, where the license we've been given by Zerto support doesn't include VSS replication, which was a pain at the time."
 

Pricing and Cost Advice

"Their licensing depended on the number of CPUs you had."
"We found that the cost of Unitrends was about the same as the Dell DR6300. We liked the fact that the Unitrends appliance was all-in-one."
"Based on a scale of one to ten, with one being low and ten being high, I would rate the pricing of this solution as a three. Also, there are no additional costs involved in the standard licensing of the solution."
"The cost of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
"Pricing model constantly changes."
"Talk with the sales guys. They can work with you on the best package."
"You should be aware how much the monthly costs are to use, what the initial costs for hardware are, and what the options to expand are, if needed."
"Zerto is like a Ferrari. It's very fast but not the cheapest solution. You're paying a high price for quality and the assurance that you will have the environment up and steady."
"It works very well as a backup and recovery solution, with frequent recovery points. It's very good. But it's too pricey for us to use it as a backup solution for all of our clients. Not every customer needs recovery points every five seconds."
"It is expensive."
"I have heard that it is expensive, but that is not my world."
"Obviously, it would be nice to have it for free. Nevertheless, a lot of effort has gone into making it a top-notch product. An excellent product with expert support is never going to be cheap. I think it's fairly priced for what it does and the benefit it brings to our business."
"It was a little bit expensive. It took a long time for us to get DR for our workstations. It's one thing when you have 15 servers, but when we needed to bring on almost another 200 users, and each was the same price as the servers, it was too expensive. But Zerto worked with us and gave us a solution that was pretty decent in terms of price."
"My experience with pricing, setup costs, and licensing was straightforward."
"The pricing seems really good. We're an enterprise customer, so we get all the bells and whistles."

We have recently implemented Zerto as a disaster recovery solution. Not only does it replicated, it allows you to created boot orders for the VM's. This means you can have your SQL server start and set an automatic delay for the applications servers. It can also be configured to bring a failover test up on an isolated network for DR testing. It can also replicate between different hypervisors. ...

So does that mean you want to have a Disaster Recovery solution where data is not on site your bunker site? but yet allows for a fast recovery in case your primary site is down? - What virtualization solution do you use? - What is the link between the 2 (?) sites? - What RPO and RTO are you aiming for? - How much data do you need to recover?
