My contact at Buffalo referred me to this link to address backing up to the TeraStation Pro.

With the new BETA firmware that allows the TS-Pro to show up as a Network Share, this seems to make sense. I'd love to hear from anyone who has successfully seen this work.
Also, Buffalo is considering allowing a Veritas Linux agent to run on their TS-Pro Linux-OS based box, but it needs to be customized to support the PowerPC processor that it has. Apparently Buffalo/Japan doesn't like the idea, but if enough of you out there were to voice an interest, that might make a difference in persuading them to take on this more enlightened and certainly functionally useful point of view.
Cheers,
