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
Getting Started
This guide shows how to archive objects into Cloud object storage and restore them as and when required, meeting the SLAs. This will illustrate the operations through SODA Dashboard.

Pre-requisite
- Cloud Backend is registered. How to register a cloud backend
- multi-cloud Bucket is created. How to create a multi-cloud bucket
How to register a Cloud backend
Create new backend using remote cloud bucket
Click on (+) for registering a storage backend
How to create a multi-cloud bucket

- Select the Retrieval Tier. Please refer the Cloud vendor docs for more details on the Retrieval Tier and the SLAs and costing for the same
- Click OK
Once the restoration of object is inititated, it may take time for the availability of the object to be downloaded. Refer cloud vendor docs for the availability corresponding to the chosen Retrieval Tier
