[ale] USB "duplicate" drive issue on CentOS

[Phil Turmel]

For the OP, bus and port and usb serial don't really matter.  He's
getting reliable /dev/disk/by-id/ symlinks -- doesn't need more.  But an
udev rule can run a script on any newly inserted disk to check if it's a
backup disk, and which one, and conditionally spawn the backup process.
