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 technical support is quite good."
"NetApp is one of the best products in this field of storage solutions."
"The most valuable feature is the snap shot."
"The solution is very stable."
"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."
"It has been 100% stable."
"The tool seamlessly moves data over the network without putting pressure on the network."
"The technology enables us to have a safe backup."
 

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."
"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."
"About a year now we have faced random issues related to power supply or auto failover failback issues which were related to bugs in the firmware."
"We must be able to integrate Flash Pool with SnapMirror."
"In the next release, I would like to get an active IP number solution."
"In the next release, I would like to see Data reduction included and WAN optimization."
"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."
"They could make continued enhancements in integration with diverse platforms for the product."
 

Pricing and Cost Advice

Information not available
"The pricing can be improved."
"It's a highly cost-effective solution"
"The solution has monthly and yearly licensing options."
"The product price is reasonable."
"The pricing could be improved."
"The cost is low compared to different vendors."
"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."
"It's part of the NetApp Firewall, so it's free."
