Saver

This util copies files while working in the background.
To set it up, select a file and a destination, and at a given interval it will be copied to another location.

Handy for keeping backups while you're working.

It can extend the autosave/backup functionality of applications that are not strong in that department, or to create an "attic" for applications that don't support that.

This application isn't really a looker. However, it's designed to work on the background.
No need to stare at it.

Main features include

You can select:
the source file to copy
the interval between making copies
the amount of copies to keep
the location where the copies must be placed
the backup copy file name
