METHODS AND SYSTEMS FOR PERFORMING PUSH-PULL OPTIMIZATION OF FILES WHILE FILE STORAGE ALLOCATIONS ARE ACTIVELY CHANGING

摘要

A method for performing full optimization of most of the files on a volume (103) in accordance with a composed optimization plan, is performed, including the separation of less frequently accessed files from those whose number on location of clusters is being more frequently modified by user applications. If the size of the largest free space (205) is greater than or equal to the size of the largest out-of-place range in the Placed Files Area (202), then a Pull operation (204) is attempted. If the Pull operation is not sucessful (303), then the method updates (304) the local data structures for tracking the range of the affected clusters (403).
