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 solution is so reliable that managers of a company don't even need to bother about knowing how NetApp SnapMirror functions in their organization."
"Technical support is excellent."
"NetApp SnapMirror's compatibility with NetApp products has helped my storage management efforts immensely, as it is part of ONTAP and all architectures based on ONTAP, including ONTAP 8 and 9."
"The most valuable feature is the data replication tool, and there is also a lot of ability for data migration."
"What I like most about this solution is its simplicity."
"The technical support is quite good."
"NetApp is one of the best products in this field of storage solutions."
"The user interface is very easy to manage. The replication is also very easy to set up."
 

Cons

"Mobility Groups crashes sometimes and a re-synchronization were needed"
"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."
"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."
"On very large data sets with a lot of changes, the interval between mirrors can be rather long."
"We must be able to integrate Flash Pool with SnapMirror."
"You need too many separate licenses for the features. 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 price needs to be improved."
 

Pricing and Cost Advice

Information not available
"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 pricing could be improved."
"The solution has monthly and yearly licensing options."
"The product price is reasonable."
