All hardware is vulnerable. You can live in a happy place, dreaming that disaster visits only others, but the day will come when it knocks on your door: usually at the most inopportune time. Think "quarter-end financial accounting!" This is why we back up everything we can. Or should...
Oracle's Sun ZFS Storage Appliances take care of many details for you, but they don't magically save your bacon: you have to work at it. Fortunately, they support the industry standard Network Data Management Protocol (NDMP) to ensure efficient data protection for backup and recovery. The Sun ZFS Storage appliance works with a variety of industry-leading backup applications (such as Oracle Secure Backup, Symantec NetBackup, and EMC Legato Networker) to offer a complete solution for data protection needs.
We have just published a paper that lays it all out for you: what NDMP is, how to configure your Sun ZFS Storage Appliance, and features and limitations in using Oracle Secure Backup, Symantec NetBackup, and EMC Legato Networker. So, before you burn the toast and start a kitchen fire with bacon, take a look at NDMP Implementation Guide for the Sun ZFS Storage Appliance!
