I forget about "rsnapshot" which can be also useful for your purpose. And here there's an article for backing up to external devices. Backups with rsnaphot to external USB drives http://workaround.org/rsnapshot-and-usb-drives As you are not going to run a daemonized version of the program, you could add a simple script from udev that runs "rsync/unison/rsnapshot/ whatever" which sends you an e-mail with a report once it finishes the copy routine by means of/using the included perl script ("rsnapreport.pl").
