Introduction to MCSBackupSystem.4-0-12.exe

This signed executable provides centralized backup management for Cisco Unified Communications Manager (CUCM) 14.0(1) and later systems deployed under Managed Collaboration Services (MCS) architectures. Designed for enterprise administrators, it enables:

  • Automated configuration snapshots of multi-node CUCM clusters
  • AES-256 encrypted backup archives with FIPS 140-3 compliance
  • Direct integration with Cisco UCS Central 1.3 monitoring platforms

Compatible with Cisco Business Edition 8000 series and UCS C-Series M6/M7 servers running CUCM 14.0(1)+, this utility aligns with Cisco’s 2025 Secure Operations Framework. The 4.0(12) release (Q2 2025) addresses critical vulnerabilities identified in Cisco Security Bulletin cisco-sa-2025-mcsbackup.
