Achieves seamless business continuity with robust scalability

The features of NetApp SnapMirror that I have found most valuable include the possibility to stop synchronization in case of high network latency and to limit the bandwidth throttle. This means limiting bandwidth when less connectivity occurs or opening wide the throttling to use the full speed of network connectivity, which we can adjust according to our needs or the needs of our customers. All of this is done without limiting business continuity, so business continuity is always guaranteed. NetApp SnapMirror's data replication feature supports disaster recovery strategies, as it is incorporated into the business continuity feature. SnapMirror is strictly related to snapshot features, a core part of ONTAP, so it's very flexible. It allows us to start with just two snapshots as a simple backup and then use them as a replication point or base for both backup and business continuity. There is no right or wrong answer, it just depends on how it works for specific needs.

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

"There are a lot of features that are excellent. The data compression during the transfer, for example, is good. The replication is great. The durability of the solution and the speed of the data moving from one site to another is impressive."

"With SnapMirror, the solution is the feature itself that is most valuable. It just replicates the data. It's very difficult to speak about, in the sense that it's similar to the features of a wheel. It is round and it's a part of an automobile."

"NetApp SnapMirror's ease of use and reliability are valuable features."

"Data protection is a valuable feature."

"The synchronous and real-time replication are the most vital features of NetApp SnapMirror"

"The performance and stability are valuable features. It seems to fulfill all the requirements."

"This solution is easy to implement and easy to use."

"They have a very effective dashboard and good reports."

More NetApp SnapMirror 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."

"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."

"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."

"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."

"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."

More QoreStor pros

Cons

"They could make continued enhancements in integration with diverse platforms for the product."

"The user interface could be simplified. They might want to have fewer options on it, to make it less complicated. There are a lot of options we never use ourselves. They're often very specialized and don't apply to us."

"If they can make the application free like other vendors or include it in all the packages, it would be great."

"At the moment, we are not using the synchronous mirror, but we can implement the synchronous mirror. The only thing is that it needs another license. This is the same issue we have with business continuity. It needs another license to be implemented. You need too many separate licenses for the features. They should add some of the aspects of the premium bundle into the basic bundle. Sometimes our customers choose other replication services because of the initial cost of the licenses."

"We have different families of storage, such as the E-Series and Flash systems, but NetApp cannot be set up between them."

"The new coursework models need to be improved. The bandwidth monitoring could also be better."

"We must be able to integrate Flash Pool with SnapMirror."

"In the next release, I would like to get an active IP number solution."

More NetApp SnapMirror cons

"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."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"The pricing could be improved."

"The product price is reasonable."

"It's a highly cost-effective solution"

"SnapMirror is extremely expensive. We had a hard time adjusting to our budget. If rated on a scale of one to ten, with ten being the most expensive, I would definitely rate it ten out of ten."

"The solution has monthly and yearly licensing options."

"The cost is low compared to different vendors."

"The pricing can be improved."

"It's part of the NetApp Firewall, so it's free."

"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 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."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
