CIPT1 v Cisco Disaster Recovery System Overview Cisco DRS provides backup and restore functionality for Cisco Unified CallManager Release 5.0 (similar to BARS in Release 4.x). Cisco DRS performs cluster-level backups and allows you to choose which nodes are restored. Cisco DRS supports regularly scheduled automatic or user-invoked data backups. Cisco DRS archives backups to a physical tape drive or remote SFTP server. Cisco DRS provides a GUI and CLI interface for performing backup and restore tasks.
