I am currently in the process of doing this in two steps:
1. Moving the cpool to a partition with LVM, so as to be able to make snapshot
binary backups in future.
2. Copying the snapshot over the network to a backup server.
I'll blog it soon and post here. In short, the fastest way to duplicate your
pool is: dd if=/dev/partition1 of=/dev/partition2
