Abstract

The Invention relates to a process for moving data objects in a computer system from a first to a second storage location, comprising: a) selecting one or more data objects from the first storage location, b) assigning at least one identifier (ID) of at least one type to each of the selected data objects, c) storing said at least one ID in a lock object, d) storing a data object, the at least one ID of which is contained in the lock object, at the second storage location and assigning the second storage location to the at least one ID in the lock object, e) deleting a data object, the at least one ID of which is contained in the lock object, from said first storage location, f) deleting an at least one ID from the lock object earliest at a time at which step e) for the respective data object assigned to that at least one ID has been completed.
