This software is for backing up files in a selected folder and in any number of subfolders of that folder.The software can be told to back up only files which have changed since the last backup (thus saving time by not copying files unnecessarily). It will give a report (without doing a backup) of all files which have changed since the last backup. It will also delete all backup files or just those which have become obsolete. This makes it easy to ensure that the set of backup files corresponds exactly to the set of current files, if an exact image is desired.This software was developed based on the assumption that one normally wishes to back up several different sets of files and to do this frequently (perhaps every day). Thus it is possible to save a particular configuration or setup in a setup file. When you wish to do a particular backup you simply load the appropriate setup file and request the program to back up all files which have been modified, or are new, since the last backup.
