Single-Instance Storage & Deduplication
Barracuda Cloud Archiving Service stores only a single copy of each unique message across recipients. However, if the same email is ingested through multiple methods (such as journaling, PST import, and ZIP import), subtle differences in transport headers cause separate copies to be archived. As a result, search results may display multiple copies of messages that appear visually identical.
