Jeff Manuszak - PeerSpot reviewer
Cost-efficient, highly scalable, and installable on different types of hardware
They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

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

"Quest QoreStor is very stable compared to our previous solution."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"The one-to-many replication functionality is helpful. While we were protecting our VMs in Azure, we were able to use the one-to-many feature to also replicate the same VMs to our new data center, in preparation for data center migration."
"Zerto is 400 times better."
"Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration."
"Zerto is fast to restore our mission-critical servers when needed."
"The live test failover is the most valuable feature because it allows me to validate that my data is protected in the event of a failure."
"Another advantage is the ease of use. You can click through instead of typing in the code. It's all already scripted down to the network adjustments within the VMs and the timed delays for servers that need to come up in sequence. Overall, it's a good package for us to use. We started using it in about 2018 and haven't looked back."
"We have had multiple live disaster recovery events where Zerto saved us a lot of downtime."
"The most valuable feature of Zerto is the quick recovery time."
 

Cons

"The ransomware protection of QoreStor could use improvement."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"We would like more mobile options. If we are at a restaurant or out and about in our normal daily lives, we would like to be able to interface via our mobiles."
"I would like to see a separate product offer for performing backups, although I think that this is something that they are expecting to release in the next version."
"The replication layer can probably be improved."
"Zerto's documentation is outdated. I'm finding it hard to find documents related to my questions. Their documentation is bad."
"Maybe the reporting for the failover test could be a little better."
"The main issue with Zerto is its user interface, which lacks flexibility and presents a steep learning curve."
"I had to have my colleague contact technical support because we had an issue where VMs in VMware were getting blocked, and we weren't able to delete them."
"There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself."
 

Pricing and Cost Advice

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"This solution is far less expensive than SRM and NetBackup."
"We have seen ROI. Several times, we needed to recover, and we were able to go to Zerto."
"There may be less expensive solutions on the market but with Zerto, you get what you pay for."
"Zerto is more expensive than competitors, making the price difference pretty high. While it is very expensive, it's very powerful and good at what it does. The cost is why we are not leveraging it for everything in the organization. If it was dirt cheap, we would have LTR and DR on everything because it would just make sense to use it."
"Licensing is based on the number of VMs to replicate. The first thing should be to get the number of VMs to replicate based on your business needs."
"We're getting our money's worth with Zerto."
"In a world where others are catching up, e.g., VMware High Availability, there needs to be a less expensive option as well. When a customer has approximately 100 VMs, if you multiply by 40, we aren't charging a very high margin on it at all since the license is so expensive. We feel their pain. That is the most expensive part of it. The storage, CPU, and RAM are a lot less. It is the licensing that is really expensive. Whereas, with an option like VMware High Availability, it is a couple dollars per month. That is our spend that we are charged by VMware, then our margin is higher on those VMs. Giving us some ability to have higher margins, as an MSP, would be a good thing."
"Staffing may be a little thin at times, but as far as budgeting what we buy, the price for this solution has not been so outrageous that we don't buy it."
