An all-in-one and cost-efficient solution that does what it promises
Zerto is very easy to use. Installation is about half an hour, and then it starts protecting the data and VMs. It is not very cumbersome. The UI is built very well. It is fairly self-explanatory. To be able to stand up a product you have never seen in half an hour and get it functioning and protecting speaks to how good the UI and workflow are. Zerto has near-synchronous replication. As a change is made on site A, it gets copied across the network to site B. We are five or six seconds behind production. If I have a heavily used system and I use traditional backups, I could be anywhere from 5 minutes to 23 hours behind. With Zerto, I am single-digit seconds behind. That works well for us. Our disaster recovery test, which used to span an entire week, now takes two days. We used to recover our servers in the first two or three days with a backup product and then test for two days before tearing it all down. Now, we spend half a day on new servers and ensuring things work with networking, etc. We test the next day, and we are done in two days. Across the entire company, we are able to save significant man-hours by shortening the test from a week to two days. We are now doing smaller tests once a month and larger tests once a year. Zerto has reduced our DR testing time by 60% to 70%. We are also able to do more disaster recovery testing. Previously, we were doing it once a year, whereas now, we are doing smaller tests once a month and our large tests once a year. In recovery point objectives, we are single-digit seconds behind. In terms of RTOs, I can recover 350 VMs in 30 minutes. It takes less than several seconds to restore a single VM. From days to 30 minutes for 350 compared to 100 VMs is an incredible time-saving in terms of RTOs and RPOs for us.

Cost savings and efficient data management improve operations but support quality varies
The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"RPO time for the copied-off VMs appears to be quite short."
"Zerto gives us peace of mind knowing that if we were attacked by ransomware, we would be able to recover data from the time before the ransomware to get us back to being fully functional."
"The replication feature where it constantly replicates and sees that data is always in sync is valuable."
"The orchestration and automation of the DR and how it replicates the VMs and then picks them up in the DR site have been most valuable."
"Zerto provides our customers with the ability to continue work, even if something happens to their office or data center."
"Zerto helps with quick recovery and integration with other processes."
"The low SLA times are valuable. It is very easy to use with a straightforward user setup."
"Zerto's single-click recovery solution offers exceptional recovery speed."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"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."
 

Cons

"The knowledge base could be improved. Sometimes, it's finicky, especially when moving storage around. We've had to redo entire processes, which was time-consuming and resulted in data loss. This has happened multiple times, and despite following support steps and contacting support, we often had to resolve issues on our own."
"Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site."
"The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up."
"It would also be nice if you could update without having to download a new installation file for Zerto Virtual Manager. Within the app, it could prompt you to install and perform the installation from within the application. Generally, it's relatively easy to use, but it gets a little complex when customers have special network requirements and need to customize how long they want the save points to be retained. We need to work with the storage team on the backend to see what makes the most sense for the client."
"With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the DRAs."
"When I have a technical question, it sometimes takes a while for tech support to respond."
"One improvement that could make it easier would be to have an easier way to track journal usage and a little bit more training around journal sizing. I've done all the training and the journal is still a gray area. There is confusion surrounding how it's billed and how we should bill clients. It would be easier if it had billing suggestions or billing best practices for our clients to make sure that we're not leaving money on the table."
"I am a little bit worried about how Zerto will work with large volumes of data, such as replication for big data and very large files."
"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."
"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 ransomware protection of QoreStor could use improvement."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
 

Pricing and Cost Advice

"The pricing for this solution is reasonable."
"If it were easier to license, and to scale it out a little bit more economically, that'd be a godsend. At the end of the day, my druthers would be to have all 200 of our servers protected by this platform. But for a company our size, that stretches our IT budget and it just doesn't make economic sense."
"Zerto's price seems fair. It's competitive."
"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."
"One of Zerto's main disadvantages is its pricing structure, which involves significant upfront costs and limited options for startups with minimal initial funding."
"Zerto is not overly expensive. It's worth what we're getting for it, but with tough times, a discount would be beneficial."
"While we find the twenty-five VM license somewhat inflexible, the actual setup costs are minimal as the product is so easy to install."
"License-wise, we budgeted $1,000 per VM. The minimum spend on it, in the beginning, can sometimes be a little bit of a headache for people, and they might have to budget creatively to get there, but once you're there, the renewals are worth it."
"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."
