I'm interested in seeing NetApp work closely with backup software vendors such as Arkeia to further NDMP support. Arkeia now supports backup of the Cobalt product line, including their (non exandable, small scale) RAID-1 NAS product.
It would be great if NetApp would contact Arkeia and extend any assistance they can in the extension of the Arkeia backup tool. This type of support can only be beneficial for both companies, and end users too!
Arkeia is at http://www.knox-software.com/. Arkeia is similar to Legato's Networker product, but supports other server platforms and costs less.
BRU is another backup product where I'd love to see NDMP support included. BRU is at http://www.estinc.com/.
NetApp customers, please voice your support to NetApp if you see value in more support for NDMP.
