Cisco Unity Connection will make use of the Disaster Recovery System (DRS) instead of the previously used Disaster Recovery Backup and Restore Tool (DiRT). DRS will provide backup of Unity Connection database (system and users), all files containing the audio portion of greetings and voice names, and all voice-mail messages. It will provide restoration of this data onto a clean, running installation of the same version of Unity Connection that was backed up.
All the capabilities of DRS described in the Cisco Unified Communications Manager section apply. For more information, see the Disaster Recovery System Administration Guide for Cisco Unity Connection
