Installed Zimbra Desktop 7.2.1 GA Build 11637 on my Windows 7 (X64) desktop yesterday.
I connected my Zimbra 7.2.1 instance and my Gmail account.
I moved the messages I want to save to my local folders.
In preferences->Backups the output "Location:" field defaults to C:\Users\Daniel\AppData\Local\Zimbra\zd_backup\
I wish to change this location to a folder that my Online backup service is already capturing (rather than add this folder to it).
Any value I put in the Location: field has no impact on where the backups are dropped.
It always outputs backups to C:\Users\Daniel\AppData\Local\Zimbra\zd_backup\.

It seems pretty straight forward, broken?
