I've written a file on the jump drive and check for its existence before 
I do the backup.  But I had a problem a while back and wrote the file to 
disk without having the jump drive mounted.  I backed up for a couple of 
weeks before I discovered that the jump drive wasn't mounted.  I would 
have thought that this was a fairly common question but maybe I'm 
missing something and not asking the right question.

Can you explain the dedicated mount point in some detail?

Thanks very much,
