This is a very good question. I always wanted a system like this:
- A program is hooked into the system's messagebus (dbus)
- It understands when a certain USB disk is attached that this is a
backup disk (either based on ID or media name or something else)
- When the disk is connected, it wil automatically trigger an rsnapshot
backup with the current timestamp
- After it has finished it displays a graphical pop-up (or a wall message
to all consoles) that the backup is finished and the disk can be
I am looking for a tool that can do this (both on Windows and on Linux).
