This module enables an automatic deduplication. The basic concept is that equal messages are replaced by links to just one of them, so that prevents the use of storage space twice or more times and helps to save a lot of space. It doesn’t require any special setup and can be done at any time, especially after migrations
The menu has only one basic option: Setup
Setup: Will take you directly to the menu whith 2 basic actions: Dedupe and Status.
Clicking the Dedupe button will schedule the operation. The Status button instead will show information about the progress of the opearation.
