Designed to make differential backups of your files and folders from source folders Here we use the term “archive” to mean archiving a copy, the original file remains in place. There are 3 modes of operation. The 1st mode uses system level hooks to detect file changes, if the file differs from the previous version, a new version is archived. The 2nd mode can be invoked at will and will create a backup set of all the changed files in the watched folder. The 3rd Mode is as scheduled.
