Archival and Retrieval

Introduction to Object archival and retrieval

SODA Multicloud provides a cloud vendor agnostic data management for hybrid cloud, intercloud, or intracloud. The goal is to provide a unified interface to support file, block, and object services across multiple cloud vendors.

Archiving data which is important but intermittently used, is valuable to keep it safe and also save cost and resource. Retrieving the archived data whenever required as per need and also retrieving it when the local data is lost is an important requirement for Availability and Business continuity. More details about the architecture and use cases can be found at ObjectArchivalRestore
