Remote Replication of ZFS Data
You can use the zfs send and zfs recv commands to remotely copy a snapshot stream representation from one system to another system. For example:
# zfs send tank/cindy@today | ssh newsys zfs recv sandbox/restfs@today
This command saves the tank/cindy@today snapshot data and restores it into the sandbox/restfs file system and also creates a restfs@today snapshot on the newsys system. In this example, the user has been configured to use ssh on the remote system.
