ZFS provides a mechanism to migrate or backup ZFS pools from one server to another using SSH.
For example, pretend you have a large ZFS pool to migrate from one server to another, but your maintenance window to perform the copy is very small. You could run the initial ZFS replication, which will take a considerable amount of time, then when your maintenance window opens, run the ZFS replication again to only copy everything that changed (the incrementals). This will take much less time and hopefully fit within your maintenance window.
The following commands show how to start the initial replication and then the replicate incrementals.
