Backing up open files under NT?

[Daniel Swan/TM]

I'm a fairly new ADSM admin with a Unix background, and the NT team has been
insisting that ADSM doesn't backup
open files, and that an add-on product is required to do so.  This seems
quite odd to me, but perhaps they know something I don't.

OTOH, perhaps they have confused open files for running databases.

How does ADSM handle open files under NT?
