Explanation
The Cisco Expressway backup archive includes: system configuration settings, security certificates and their private keys, and call detail records (CDRs). Security certificates are critical for TLS operation and are preserved in backups to avoid re-enrollment after a restore. Call records (CDRs) are stored logs of completed calls and are included in the backup. Log files are transient diagnostic data and are not backed up. Current call states are ephemeral runtime data that cannot be meaningfully backed up or restored. IP address configuration is part of the system configuration, which is backed up, but raw IP addresses alone are not a distinct backup category.
