METHOD AND SYSTEM FOR TRACKING CHANGED FILES

摘要

A portion of a first storage stores identifying information of files to be processed by a computer. The files are stored in a second storage, with each file having associated identifying information which identifies the file, and each file including an update sequence value which indicates an order in which the file is to be processed by the computer. A threshold value is provided which is set equal to a largest update sequence value retrieved from the files that have been processed by the computer. In response to a loss of the file identifiers stored in the portion of the first storage, the file identifier for each file whose update sequence value is beyond the threshold value is stored in the portion of the first storage.
