Object Storage Backup is a backup strategy where the source or destination is API-addressed object storage rather than a traditional filesystem.
Simple definition
Object Storage Backup is a backup strategy where the source or destination is API-addressed object storage rather than a traditional filesystem. It belongs to the Sauvegarde / PRA vocabulary and is useful when reading architecture diagrams, product documentation, logs, or administration procedures.
What is it used for?
Its main purpose is to store scalable, offsite, or immutable copies in S3/Azure Blob-compatible services and equivalents. The practical value depends on the surrounding architecture, security model, and operational requirements.
How does it work?
Data is split into objects and transferred through APIs with metadata, retention, and optionally Object Lock/immutability.
Key points
- Scope: A backup strategy where the source or destination is API-addressed object storage rather than a traditional filesystem.
- Operational goal: Store scalable, offsite, or immutable copies in S3/Azure Blob-compatible services and equivalents.
- Implementation: Data is split into objects and transferred through APIs with metadata, retention, and optionally Object Lock/immutability.
Points to watch
A backup is reliable only if restore is tested; document RPO/RTO, retention, immutability, and chain dependencies.
In short
Object Storage Backup = a backup strategy where the source or destination is API-addressed object storage rather than a traditional filesystem. Use it when you need to store scalable, offsite, or immutable copies in S3/Azure Blob-compatible services and equivalents.
