CORRECTNESS IRRESPECTIVE OF ORDER Russian patent published in 2015 - IPC G06F9/44 G06F3/06 G06F12/00 G06F11/00 

FIELD: physics, computation hardware.

SUBSTANCE: invention relates to method, system and computer data carrier for maintenance of correctness in storage system. In compliance with proposed method, one or more indications of objects involved in transaction are obtained. Location of the first set of storages locations for objects involved in transactions is determined. Logical copies of said objects are created and modified in the transaction context. Second set of storage of said logical copies is defined. Association is created to relate logical copies of objects in elementary unit. One or more requests for writing said association and logical copies to storage are output. At the same time, originals of said copies are maintained in the storage. After refusal recovery job is executed which includes determination if the copy of all said objects as modified in transaction context in the storage and rejection of modification for this copy of all objects in storage.
