Long-term user praises cost savings and reliability of disaster recovery solutions

There is only one thing to note: the agent has to be up-to-date when SCCM or any third-party tools are doing patching activities. If their agent version is mismatched and the health status is critical, you will not be able to perform your Azure Site Recovery. Recently, I worked with a mass issue related to Recovery Services Vault, and the VM support engineers are taking a lot of time to extend support to the customer. When you raise a call, they wait too long, and even if you request an engineer to set up a call for severity B cases, they are not ready to communicate over the phone, preferring email instead.

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

"The solution is secure, reliable, and scalable."

"Provides generally good performance, from protection to production to failover to data recovery."

"Azure Site Recovery's automated file synchronization was a game-changer in managing legacy systems."

"It is a very stable product and very scalable."

"Despite the cost concerns and downtime management, I would still recommend Azure Site Recovery."

"What I like best about Azure Site Recovery is that it's easier to use because my organization already has Azure as an Active Directory solution."

"Our primary use case is for disaster recovery and business continuity and disaster recovery (BCDR)."

"The solution is very easy to use."

More Azure Site Recovery pros

"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."

"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 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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"Quest QoreStor definitely saved us money."

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

More QoreStor pros

Cons

"Azure Site Recovery's deployment is complex. There are a lot of bugs, and it needs to improve stability."

"Could have more integration with other platforms."

"Currently, Azure Site Recovery does not support shared disk options. Moreover, it does not support services like AppConfig or App Services."

"I conveyed the feedback to the agent, suggesting an increase in the agent count in our VNS in the USA. I also addressed notification concerns, as some issues didn't trigger alerts during a recent call."

"When it runs, it runs well but when it doesn't run, the solution needs to make it clearer as to why and what the troubleshooting process is. All this would be possible if the error logging was streamlined a bit."

"The support team took a lot of time to respond and was not very professional."

"The immutable backup could be better."

"It could include more of a backup and recovery."

More Azure Site Recovery cons

"The ransomware protection of QoreStor could use improvement."

"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."

"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 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."

"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."

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"They have a license to pay."

"It should have more straightforward billing. The billing was what got funky. It was really cheap. We would pay based on the usage. We paid around $225 a month for site-to-site replication."

"The tool's licensing is yearly and not expensive."

"Azure Site Recovery is a very reasonably priced product."

"The tool is expensive. What is expensive to me might not be expensive to you. As I mentioned, we seek ways to reduce our costs. If the price goes down, that would be great. I rate the tool's pricing a six out of ten."

"I'm not sure about the Azure Site Recovery pricing, but my organization gets monthly bills from providers."

"Azure Site Recovery is neither very expensive nor very cheap."

"Azure Site Recovery is affordable."

"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."
