The Disaster Recovery System (DRS), which can be invoked from Cisco Unified Communications Manager Administration, provides full data backup and restore capabilities. The Disaster Recovery System allows you to perform regularly scheduled automatic or user-invoked data backups.
The Disaster Recovery System includes the following capabilities:
•A user interface for performing backup and restore tasks.
•A distributed system architecture for performing backup and restore functions.
•Archived backups to a physical tape drive or remote SFTP server.
Depending on the customer service level agreement (SLA), a viable disaster recovery model is the warm standby model. In this model, a second Cisco Unity Connection server is deployed at a remote or disaster recovery location, but its database is not populated. Nightly DRS backups are performed on the live Connection system, and these backups are stored at the remote or disaster recovery location. In the case of disaster, the backup is restored onto the Connection server at the remote or disaster recovery location. A license file for the backup server can be purchased in advance or the license file from the original Connection system can be transferred to the backup Connection server.
