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

"Technical support is excellent."
"It's a stable solution; it just works."
"Having real-time replication gives us the capability to recover from any data loss as quickly as possible."
"My understanding is that the technical support is good, but we don't need much support because it's working fine."
"NetApp is one of the best products in this field of storage solutions."
"The solution is so reliable that managers of a company don't even need to bother about knowing how NetApp SnapMirror functions in their organization."
"Previously, we were using a Windows-based file server and didn't have the high availability, replication to a secondary site, or snapshot capability, which is what we were looking for."
"The technical support is quite good."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"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."
"Quest QoreStor definitely saved us money."
"QoreStor has helped us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
 

Cons

"The tool should also work on third-party solutions."
"It is not as efficient as it needs to be. It doesn't compress the data really well when it is forwarded to a secondary site. The download performance could be better."
"In the next release, I would like to get an active IP number solution."
"The solution's dashboard and reporting could be improved."
"In the next release, I would like to see Data reduction included and WAN optimization."
"Technical support is only available if there is a problem."
"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 installation could use improvement. The initial installation was a little touchy and it's not really user-installable."
"They need to increase their maximum capacity."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"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."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."
 

Pricing and Cost Advice

"It's a highly cost-effective solution"
"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."
"The solution has monthly and yearly licensing options."
"The pricing could be improved."
"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."
"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."
"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."
