De-Duplication Filter for Symantec Enterprise Vault Configuration Guide › Configuring the De-Duplication Filter › Configure the De-Duplication Filter

Configure the De-Duplication Filter

To configure the De-Duplication filter, you need to edit registry values located in the following registry key:

HKEY_LOCAL_MACHINE\Software\ComputerAssociates\CA DataMinder
    \CurrentVersion\SEV_Deduplication

Within this registry key, edit these registry values:

EnableFilter

Type: REG_DWORD

Data: Defaults to 0. Set this to 1 to enable the De‑Duplication filter.

TestMode

Type: REG_DWORD

Data: Defaults to 1. This value enables you to test that the De-Duplication filter is working correctly before you go live. It mimics how the filter will operate when an email is processed. For example, if this value does not exist or is set to 1 then, when a duplicate e‑mail is detected, the filter logs the action that would be taken had TestMode not been enabled. However, no emails are actually deleted.

This value must exist and be set to 0 to disable test mode and enable normal operation of the De‑Duplication filter, where duplicate emails are actually deleted.

EliminateArchiveDuplicates

Type: REG_DWORD

Data: Defaults to 0. Set this value to 1, to delete duplicate emails from the SEV archive. This value does not control the De‑Duplication of e‑mails from the CA DataMinder database, which always takes place, unless TestMode is enabled.

LogLevel

Type: REG_DWORD

Data: Defaults to 2. This determines the level of logging for the De-Duplication filter. For example, you can configure the De-Duplication filter to only log errors or important system messages. Log entries are written to WgnSevDD_<date>.log file, where <date> is the date and time when the log file was created. The location of the log file is specified in the LogFilePath registry value.

Supported log levels are:

• Errors only
• Errors and warnings
• Errors, warnings, plus any extra information

LogFileMaxBytes

Type: REG_SZ

Data: Defaults to 1,000,000 (1MB). Specifies the maximum size for each log file. When the current log file reaches its maximum size, the De-Duplication filter creates a new log file.

LogMaxNumFiles

Type: REG_DWORD

Data: Defaults to 10. Specifies the maximum number of log files. When the maximum number of log files exists and the maximum size of the most recent is reached, the oldest log file is deleted to enable a new one to be created.

LogDuplicatesAsWarnings

Type: REG_DWORD

Data: Defaults to 0. Usually, duplicate emails generate an Informational level log entry to indicate that the e‑mail will not be archived as it is a duplicate. If this value is set to 1, then the same logs are generated but at a Warning level.
