Each of these copies corresponds to the content of the object at a specific moment in the past. This functionality can be used to protect the objects of a bucket against overwriting or accidental deletion. anonymous@undisclosed.example.com (Anonymous) en:navody:object_storage Mon, 19 Sep 2022 17:25:35 +0000 https://du.cesnet.cz/en/navody/object_storage/start?rev=1684400430&do=diff Object storage As the name promises, object storages are different from common data storages with file systems. Object storage stores data as objects not as data blocks in the case of common file systems. Metadata are associated directly with a particular object. It eliminates the need for a hierarchical structure used in common file systems.
