Configuring Versioning for a Bucket (SDK for Node.js)
If you have any questions during development, post them on the Issues page of GitHub.
Function
You can enable versioning to automatically maintain previous versions of an object. When versioning is enabled, you can access earlier versions of an object to recover your data in the event of accidental actions or application failures. For more information, see Versioning.
This API configures versioning for a bucket.
Restrictions
- To configure versioning for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketVersioning in IAM or PutBucketVersioning in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- To learn about the mappings between OBS regions and endpoints, see Regions and Endpoints.
