Module backend 

Storage backend implementations.

This module contains the Backend trait and its implementations. Each backend adapts a specific storage system (BigTable, GCS, local filesystem, S3-compatible) to a uniform interface that StorageService consumes.

Two-tier routing is encapsulated in TieredStorage and can be configured via StorageConfig::Tiered.
