Disaster recovery has strengthened critical grid operations and maintains regulatory compliance
A couple of things where AWS Elastic Disaster Recovery could improve are the granular testing of OT workloads. It would be helpful to have fully isolated test recoveries for our OT data, such as SCADA or pole telemetry, without impacting replication, to help validate disaster recovery readiness more frequently. Additionally, advanced reporting and analytics would be beneficial. If the tool could provide more built-in dashboards to show replication lag trends, failover readiness, or system dependencies, it would save time and improve transparency for both field teams and regulatory reporting. In terms of integration, tighter integration with our asset management systems and GIS databases would streamline automated recovery of linked OT systems and data relationships, making failover more efficient. There should also be more fine-grained alerts for replication lag or orchestration failures, with customizable thresholds for different types of workloads to improve proactive incident response. My advice would be to start with a clear disaster recovery strategy. Identify which IT and OT systems are critical, calculate the recovery time objective, and which assets need replication first. Keep latency-sensitive or legacy OT systems on-premises while replicating core IT workloads to AWS for fast, reliable failover. It is essential to keep testing failovers regularly, as it builds confidence and uncovers gaps that help ensure smooth operation during real incidents. Actively monitor costs by paying attention to replication storage and compute usage since AWS Elastic Disaster Recovery is pay-as-you-go, which allows us to save thousands of dollars annually. Connecting disaster recovery events with field operations, SCADA systems, and asset management dashboards streamlines operational responses. The AWS team is great, and engaging with their support and architects, along with their documentation and best practices, is very helpful.

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

"AWS Elastic Disaster Recovery has allowed us to maintain critical operations during high-impact natural disasters, protecting both our customers and our assets while demonstrating measurable improvements in our response time and regulatory compliance."
"Technical support has been very good. They usually respond quickly to our requests.​"
"Since deploying AWS Elastic Disaster Recovery, we have mostly seen an improvement in uptime, which contributes to reducing downtime."
"What I like about ECR AWS is that it is a fully managed service, so I don't need to manage the underlying infrastructure or worry about scalability in AWS concerning building, maintenance, security, and high availability."
"The solution is dependent on the network bandwidth. For example, if they have a bandwidth of 10Mbps the solution will run a little heavier. If the bandwidth is good the solution runs well."
"AWS Elastic Disaster Recovery is a robust and reliable solution for disaster recovery needs."
"We have never had any issues with scalability."
"The initial setup is pretty straightforward, it's not complex."
"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."
"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."
"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."
"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."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
 

Cons

"The failback could be improved. It should be more intuitive."
"The user interface, customer support, and the recovery time for the current customer query could use improvement."
"I set up a test, deleted the source, and went to fail it back, and it didn't work."
"Definitely there should be better logging. From a customer perspective I would like to see more logs on what is happening. If there is an issue, I would like to know what the problem is. Right now, we have to depend on the support of the vendor to check and let us know, because we don't have access to a lot of logging information."
"In its current state, ECL integrates with CloudWatch for basic logging and monitoring, yet improvements could include more detailed logs for specific actions, like when I perform actions such as push or pull."
"The solution's network setup and a lot of the control tower setup could be improved."
"A couple of things where AWS Elastic Disaster Recovery could improve are the granular testing of OT workloads."
"An improved AWS pricing model is needed."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"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."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Where the price adds up, there are CloudEndure licenses, then there is the AWS environment, and finally, there is the AWS storage, so cumulatively, it adds up."
"We were happy with the pricing that they gave us."
"It has saved us money from having to buy hardware for disaster recovery."
"The pricing is better now that they had come out with the Tier 2 which replicates a little less often. In comparison to what I would have been spending with any other type of solution, the pricing is fair."
"I feel the product's pricing is a good value. Licensing is pretty straightforward."
"I rate the price of CloudEndure Disaster Recovery a six out of ten."
"CloudEndure Disaster Recovery is charging clients $20 to do the DR backups. It is an expensive solution."
"They license us on a per machine basis. We have a set number of machines, which we have licensed.​"
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
