Deleting an Object

Functions

You can perform this operation to delete an object. If you try to delete an object that does not exist, OBS will return a success message.

Versioning

When versioning is enabled for a bucket, a deletion marker with a unique version number is generated when an object is deleted without specifying the version. However, the object is not actually deleted. If versioning is suspended for a bucket and no version is specified when you delete an object, the object whose version number is null is deleted, and a deletion marker with version number null is generated.

To delete an object of a specified version, the versionId parameter can be used to specify the desired version.

WORM

OBS automatically enables versioning when you enable WORM for a bucket. If you delete an object without specifying a version ID, OBS does not really delete this object thanks to versioning, but inserts a delete marker with a unique version ID, which turns into the current version. If you specify a version ID when deleting an object protected by WORM, OBS prevents you from deleting this object and returns a 403 error. Delete markers are not protected by WORM.
