Abstract:
Systems and methods for providing object versioning in a storage system may support the logical deletion of stored objects. In response to a delete operation specifying both a user key and a version identifier, the storage system may permanently delete the specified version of an object having the specified key. In response to a delete operation specifying a user key, but not a version identifier, the storage system may create a delete marker object that does not contain object data, and may generate a new version identifier for the delete marker. The delete marker may be stored as the latest object version of the user key, and may be addressable in the storage system using a composite key comprising the user key and the new version identifier. Subsequent attempts to retrieve the user key without specifying a version identifier may return an error, although the object was not actually deleted.

Claim (Index 3):
The method of  claim 1 , further comprising, subsequent to said storing the delete marker object:\n receiving a third request to perform a delete operation, wherein the third request specifies the particular user key but does not specify a version identifier; and in response to receiving the third request:\n creating a second delete marker object comprising a second composite key, wherein the second delete marker object does not contain object data, and wherein creating the second delete marker comprises:\n generating a second, unique version identifier; and \n concatenating the second, unique version identifier and the particular user key to generate the second composite key;\n refraining from deleting any of the plurality of objects stored in the memory or the delete marker object; and \n storing the second delete marker object in the memory.
