Summary:A system and method to optimize memory usage during data backup. The system generates lists of files and attributes corresponding to local files and backup files, selectively allocates storage of the lists to the hard disk and/or memory, compares the lists, and updates the backup files to reflect differences between the local files and the backup files. At least a portion of the lists may be allocated to hard disk storage based on preestablised criteria such as historical memory usage, a dynamic determination of the amount of available memory relative to the amount of memory needed to perform a current backup, or a prior determination of the amount of available memory compared to the amount of memory required to perform a current backup. In this manner, the present invention efficiently utilizes memory resources to perform incremental backup procedures quickly and reliably and facilitates large scale file backup.
