Create a SQL Server Agent Job to Archive Database Mail Messages and Event Logs

Copies of Database Mail messages and their attachments are retained in msdb tables along with the Database Mail event log. Periodically you might want to reduce the size of the tables and archive messages and events that are no longer needed. The following procedures create a SQL Server Agent job to automate the process.

Prerequisites

The new tables to store the archive data might be located in a special archive database. Alternatively the rows could be exported to a text file.

Top

Recommendations

In your production environment, you might want to add additional error checking and send an e-mail message to operators if the job fails.

Permissions

You must be a member of the sysadmin fixed server role to execute the stored procedures described in this topic.

Overview of the Process

  • The first procedure creates a job named Archive Database Mail with the following steps.

    1. Copy all messages from the Database Mail tables to a new table named after the previous month in the format DBMailArchive_<year_month>.

    2. Copy the attachments related to the messages copied in the first step, from the Database Mail tables to a new table named after the previous month in the format DBMailArchive_Attachments_<year_month>.

    3. Copy the events from the Database Mail event log that are related to the messages copied in the first step, from the Database Mail tables to a new table named after the previous month in the format DBMailArchive_Log_<year_month>.

    4. Delete the records of the transferred mail items from the Database Mail tables.

    5. Delete the events related to the transferred mail items from the Database Mail event log.

  • Schedule the job to run periodically.
