The scenario
A production environment with web, app, and database servers uses a primary SAN. Backups are written to a physically isolated backup network containing a backup server, a rotating disk array for fast restores, and a tape library for long-term archival.
What is in this drawing
Read the decisions behind it.
01
Physically separate backup zone with no network link to production
02
Use switching within backup zone for disk and tape devices
03
Maintain production firewalled WAN access while keeping backup network isolated
Use for documenting air-gapped backup architectures where data leaves production via physical media transfer, and for separating rotating disk and tape archive tiers.
