It very easy to setup and manage unless you have network problems.
There were restrictions when migrating from older to newer versions of Windows. As soon as the target disk is mounted on the higher level of Windows, NTFS file system will automatically be upgraded by Windows and will no longer be compatible with the source system. This means that migration cannot be resumed and a full refresh was needed to re-synchronize the source and target disks.

Reliable replication has transformed disaster recovery and supports realistic dev-test environments
The best feature NetApp SnapMirror offers is block-level incremental replication, which is the foundation of everything. After the initial baseline transfer, only the changed blocks move across the wire, not entire files or volumes. In a busy storage environment, that is the difference between replication that fits in your backup window and replication that hammers your network all day. NetApp SnapMirror has positively impacted our organization by taking us from a theoretical DR capability, meaning we had a secondary site but had never fully tested a failover, to a validated, tested, documented DR process that we run quarterly, which is a fundamental change in our risk posture. Management can now say with confidence that if the primary site goes down, we recover within two hours with zero data loss on critical systems.

Quotes from Members

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

Pros

"TDMF resolved these problems with easy and fast data migrations."
"The most valuable feature is the snap shot."
"The user interface is very easy to manage. The replication is also very easy to set up."
"Technical support is excellent."
"Having real-time replication gives us the capability to recover from any data loss as quickly as possible."
"Management can now say with confidence that if the primary site goes down, we recover within two hours with zero data loss on critical systems."
"Overall, the product is very good. It's an easy to use tool."
"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."
"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."
 

Cons

"Mobility Groups crashes sometimes and a re-synchronization were needed"
"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."
"We must be able to integrate Flash Pool with SnapMirror."
"The tool should also work on third-party solutions."
"If they can make the application free like other vendors or include it in all the packages, it would be great."
"The solution's dashboard and reporting could be improved."
"On very large data sets with a lot of changes, the interval between mirrors can be rather long."
"The price could be cheaper."
"In the next release, I would like to get an active IP number solution."
