I am actually using a backup program - Yosemite Backup. No backup script. Not sure if I could tell YB to run a script before and after. I will look into that. Finding the scsi/usb drive is not an issue.

This has worked before. I had two identical WD usb drives and things worked well until we noticed that one had a very slow throughput. It was RMA'd and the one that came back has a different model number even though they look the same and have the same capacity.
