There was a thread on this forums about Zimbra creating a HOT backup add-on for FOSS. Any latest development?
I think it will be a very big relief for all.
In addition a tool that connects to zimbra and then bulk-converts user mailboxes to PST files will help migration from one Zimbra server to the other, especially during an upgrade.
