For frequent backup it must be snappy. And to not forget doing it, it should really be automatic. From experiments, doing a raw block level clone is 2-3 times faster than naive file level copy (unless source drive is an SSD or unless drive is sparsely used). So for system backup, you can have a dd script with opt-out option run in a shutdown hook. Then modify the bootloader with recovery tools which can also boot up the mirror [http://bit.ly/loader-menu].
Unlike a RAID setup there's no observed performance penalty to pay, no danger of controller errors and it's easy to swap a cradle mirror and bring it off-site per round robin fashion [http://bit.ly/cradle- drive].
