The diagram below shows how theDe-Duplication Filter and optionally the EV server agent work with the SEV host server to: process emails from journal mailboxes; remove duplicate emails; optionally integrate with policy engines to apply policy and assign smart tags; and then archive them.
De-Duplication Filter for Symantec Enterprise Vault architecture
An email is sent from a user in the New York office to the ‘All Marketing’ distribution list.
There are members of the distribution list in the New York, Boston and Toronto offices, each of which runs its own email server with its own journal. A copy of the email now exists on each journal server.
The SEV server hosts two custom filters: the De-Duplication Filter (3a) and, optionally, the EV server agent (3b).
The De-Duplication Filter processes these emails via the De-Duplication database, which stores a unique ID for each email. The ID is identical for each duplicate email, enabling the De-Duplication database to filter out emails already processed by the filter. The New York copy is processed first, and the other two copies are identified as duplicates.
After De-Duplication, the single remaining e‑mail is passed by the EV server agent and sent to a CA DataMinder policy engine for processing.
SEV then sends a single copy of the email to the archive.
