I have a 4-drive RAIDZ2 zpool which contains two datasets, one of which is encrypted with a password. I am trying to replicate these two datasets onto an external eSATA HDD for offline backup purposes. The replication of the unencrypted dataset is fine, but I can't figure out how to make a 1:1 replication of the encrypted dataset which retains its properties (compression enabled, and most importantly, encryption enabled). When I try to replicate it onto the external HDD, it just creates an unencrypted copy of the source dataset. I need it to retain its encrypted status (with the same password etc). The example at Encrypting ZFS File Systems - Oracle Solaris 11.1 Administration: ZFS File Systems (Example 5-4 Sending and Receiving an Encrypted ZFS File System) isn't very informative.
