Introduction

This document describes how to back up Safelists/Blocklists (SLBL) on the Cisco Email Security Appliance (ESA).

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on the Cisco Email Security Appliance (ESA) and all versions of AsyncOS.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Generate BLSL Backup Files

From the ESA web interface, navigate to System Administration > Configuration File > End-User Safelist/Blocklist Database (Spam Quarantine). You can generate backup files from this location.

Note: If you have several ESAs in cluster, you must upload the backup files to each opposing unit.

Enter the slblconfig command into the CLI in order to import and export the SLBL configuration:

> slblconfig

End-User Safelist/Blocklist: Enabled

Choose the operation you want to perform:
- IMPORT - Replace all entries in the End-User Safelist/Blocklist.
- EXPORT - Export all entries from the End-User Safelist/Blocklist.
[]> export

End-User Safelist/Blocklist export has been initiated...
Please wait while this operation executes.

End-User Safelist/Blocklist successfully exported to
slbl-782BCB64XXYY-1234567-20140717T020032.csv (200B).

You must then access the ESA via File Transfer Protocol (FTP) in order to retrieve and retain the newly-created, exported SLBL configuration:
