If the version you are adding tags to is a delete marker, OBS returns 404 Not Found. Tags cannot be set for files in parallel file systems. An object can have up to 10 tags. Constraints on the tag key and value: A tag key is case sensitive and must be unique.
Versioning OBS automatically enables versioning when you enable WORM for a bucket. In such case, the object you uploaded to the bucket will be assigned a version ID.
OBS does not involve folders like in a file system. All elements in buckets are objects. To create a folder in OBS is essentially to create an object whose size is 0 and whose name ends with a slash (/).
The minimum part size supported by an OBS 3.0 bucket is 100 KB, and the minimum part size supported by an OBS 2.0 bucket is 5 MB. You are advised to perform multipart upload to OBS 3.0 buckets.
