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

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"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."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"Quest QoreStor definitely saved us money."
"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."
"The simplicity of use is valuable. It is easy. We just click Failover and do it. It is pretty straightforward. If someone wants to do a test failover, they log in to the console and do a test failover"
"In our DR testing, Zerto allows us to go work on other things while it takes care of everything. That's valuable because we know that we can still hit all of our SLAs in a real disaster."
"I love Zerto's near-synchronous replication. I've been using Zerto for three years at my current employer and many years before that. It's been great. Anywhere I've used it, it's made the failover process a lot easier so that pretty much anybody can do it. This feature is our number one priority because we can keep our critical apps running if we have a failure, or even if we have a misconfiguration, it's very easy to recover something quickly."
"Zerto has improved our confidence tremendously, and it has reduced the RPO of any potential restoration needs."
"The continuous replication with a low recovery point objective (RPO) is crucial for us."
"Zerto's single-click recovery solution offers exceptional recovery speed."
"I've used backup solutions like Veeam in the past, but Zerto seemed like a better, faster solution. We adopted Zerto because of the speed, and because we wanted to do everything in-house."
"The ability to have a RPO of seconds has enabled us to restore data to just before an incident has occurred, which certainly saves a lot of time and money."
 

Cons

"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The ransomware protection of QoreStor could use improvement."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"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."
"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."
"This solution could be improved if it met all the requirements that we look for including supporting multiple operating systems. We would prefer to use one solution for DR and backup."
"Zerto's price has room for improvement."
"Some of the cloud instructions around VNets and peering of networks could be clearer with some best-case examples. It is more complicated once you move into the cloud than running it on-premises. Actually doing these things is quite easy in the cloud and with Azure, but understanding how it fits in my environment can be quite a head-scratcher at times."
"Some of the integrations with our internal tools, in particular, company-specific ones, do not work. In cases like this, we have to ask for additional support."
"Migration of complex VMware and Hyper-V solution. Using Zerto to replicate to azure and S3."
"Some of the features need improvement. One would be, as you're creating a Move group or a VPG, as they call it, it should either autosave or have the ability so that you can save it for coming back to later because if the setup times out, you lose all your work. That would be a nice improvement to have."
"Zerto should add the capability to replicate the same VM to multiple sites."
"It would be difficult to do, but I would love it if Zerto handled some of the scripting and things necessary to do a recovery. For example, it would be helpful if the solution could update the DNS to point to a new location. It would be nice to automate some of those tasks that you have to do to recover a VM and they were kinda out-of-the-box point-and-click things rather than things that required you to write a script."
 

Pricing and Cost Advice

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance."
"Pricing is one area where there could be some improvement. We would like to see a consumption model that would charge in a DR scenario, where you're failing over and consuming those resources, instead of a per-protected-node model. Or it could be a model based on the amount of storage space you're protecting."
"The last time I looked at pricing, it was very good. It's much cheaper by far than VMware."
"I would like to see different service levels. They're good, but it still takes a lot of our budget in ops."
"The pricing seems reasonable. It's still within what we consider to be value-add."
"The pricing is very reasonable."
"I ballpark Zerto's pricing at about $1,000 per VM, which I find fair for what it does, but the cost of entry was tough initially due to the minimum number needed to start. I really needed to prove to the business that it was worth the investment."
"Zerto is fairly expensive, but worth it."
