Obtaining the Versioning Status of a Bucket (SDK for Go)

Function

OBS keeps multiple versions of an object in a versioning-enabled bucket. That way you can quickly retrieve and restore every object version as needed, or recover data from both accidental actions and application failures. For more information, see Versioning.

This API obtains the versioning status of a bucket.

Restrictions

Method

func (obsClient ObsClient) GetBucketVersioning(bucketName string) (output *GetBucketVersioningOutput, err error)
