Just create a file called "THIS_IS_THE_USB_DRIVE" on the drive itself,
then let your cronjob check for it like this:
[ -f /mnt/usb/THIS_IS_THE_USB_DRIVE ] && rsync -aHPp /data/ /mnt/usb/data/
Of course, a script would be suitable - it might mail somebody, then
"while [ ! -f /mnt/usb/THIS_IS_THE_USB_DRIVE ] ; do sleep 1m ; done"
to wait for the drive to appear.
HTH,
Tino.
