What is the latest "status" for multiple instance backups with Avamar on Windows clients?

Works but "unsupported"?

Also, relative to whatever that status is, I have seen some "documentation" on how to set up multiple client instances for Windows file system client backups, but it's just a very "sparse" Word document without any indication that it is related to a certain IT company we all know and love.

I have seen much more "official" looking documents for other multiple instance solutions, such as backing up EPIC databases on AIX servers - has any "official" Windows equivalent version for file systems been created yet?

All comments/feedback appreciated - thanks.
