Backup Storage & Infrastructure

Fixed-capacity hardware appliances buy immutability in vendor-sized increments. What that costs over a refresh cycle, and what changes when the storage layer is software-defined.

Immutable storage keeps data from being changed or deleted for a set period. How it differs from WORM, how deletion locks actually work, and what it does and does not protect against.

A PBBA bundles backup software and storage hardware into one box. What that buys you, what it costs in flexibility, and how it compares to running the same software on your own infrastructure.
