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 delete request that does not specify a version ID cannot permanently delete the object. Instead, OBS creates a delete marker with a unique version ID. When versioning is suspended for a bucket, a delete request that does not specify a version ID deletes the object whose version ID is null and creates a delete marker with a version ID of null.
To delete an object of a specified version, the versionId parameter can be used to specify the desired version.
To restore a deleted object, you need to specify the delete marker version in the versionId parameter when deleting it.
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.
