The docs at Symantec are truly horrible.

Novell's site offers little other than to say that NetBackup is tested and approved for OES 2.

I see some postings about not being able to backup compressed NSS data (that would suck) with NBU (it'll decompress the data). But I don't know which NBU version or OES version the people are using.

Ever since Symantec took over Veritas their support is even worse.
