*Very clever to have found this*, and this "once upon a time" could explain 
some other strange bugs.

When a drive or folder is mounted it replaces and hides what was there before. 
You can find it again by unmounting or better by examining from outside using a 
live CD, thus bypassing the mounting and avoiding for example writing in the 
previously empty /home folder if you had a home partition.

I am curious to know.
You could at least look under all the partitions that get mounted.
As for you backup, in order to prevent further occurrences of this mishap, I 
would suggest you launch it through a script that would first check that you 
partition got mounted (it might use the output of remount or check the 
existence or absence of a file). Don't ask me for more details, I'm no expert 
on writing scripts.
