You welcome. :-)

ZFS only supports snapshots (and clones, being writable snapshots)  
within the same filesystem. A snapshot can be recreated to another  
storage pool on the same host, or remote host using "zfs send" and  
"zfs recv".

If you are looking for block-based snapshots or remote replication of  
zfs storage pools, review the "AVS" blog and OpenSource project pages  
listed below.
