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-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.

Quotes from Members

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

Pros

"The synchronous and real-time replication are the most vital features of NetApp SnapMirror"
"This solution provides safety and data protection for my customers."
"My understanding is that the technical support is good, but we don't need much support because it's working fine."
"What I like most about this solution is its simplicity."
"It's a simple and efficient tool to build a disaster recovery solution that involves many applications such as Oracle, SQL, VMware, and Hyper-V."
"This solution is easy to implement and easy to use."
"The tool seamlessly moves data over the network without putting pressure on the network."
"NetApp SnapMirror's ease of use and reliability are valuable features."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
"Quest QoreStor definitely saved us money."
 

Cons

"We have different families of storage, such as the E-Series and Flash systems, but NetApp cannot be set up between them."
"Synchronous replication with read-write on both sides in both data centers is powerful but risky since it is greatly affected by high network latency."
"Multiple tasks in the solution are made by the command line and the GUI can be improved to perform complex tasks."
"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."
"The new coursework models need to be improved. The bandwidth monitoring could also be better."
"The NetApp storage is entry-level storage. I'd like to see compression and deduplication and encryption improved, and I'd like to have real-time replication so I have a zero RPO."
"The GUI can be improved to perform complex tasks"
"I think that NetApp needs to improve the performance of SnapMirror with controller volume access."
"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."
"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."
"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."
"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 installation could use improvement. The initial installation was a little touchy and it's not really user-installable."
 

Pricing and Cost Advice

"The solution has monthly and yearly licensing options."
"The product price is reasonable."
"The pricing can be improved."
"The cost is low compared to different vendors."
"It's part of the NetApp Firewall, so it's free."
"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 pricing could be improved."
"It's a highly cost-effective solution"
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
