Enterprise-grade dual-datacenter backup architecture using Commvault with primary Dell HyperScale storage at DCL and secondary HP Apollo HyperScale storage at MoroHub DR site, connected via 2 Gbps WAN link. Master Server, metadata database, and vSphere infrastructure replicate across sites to enable failover, while backup clients stream data to Media Agents across isolated 10.181.1.0/24 and 10.115.191.0/24 segments. Fujitsu Eternus TL260 tape library provides air-gapped offline copies for ransomware protection and long-term retention. This architecture demonstrates enterprise resilience patterns: geographic redundancy, network isolation, immutable backups, and automated DR activation for protected VMware, NAS, databases, and file systems. Fork and customize this diagram to model your own multi-site Commvault deployment, adjust node counts, or swap storage vendors. Consider adding monitoring dashboards or backup policy tiers for production implementations.
