--As for the rest, it is mine.

But if the directory *you are restoring to* has x y and z, do they still 
exist after the restore?  Does tarsnap *delete* them because they weren't 
in the backup set?  Or does it just restore all the files that *were* in 
the backup set, and leave the rest alone?  That's the question.

In other words if:

root@pvpn-sf:...tmp/test # ls
x       y       z

and you do:

tarsnap -x -f test2 /tmp/test

do you have:
root@pvpn-sf:...tmp/test # ls
a       b       c       x       y       z

or do you have:
root@pvpn-sf:...tmp/test # ls
a       b       c


There are reasons to want both ways, but it's nice to know which it will 
be.  ;)

I think tarsnap does the former: Restores files without touching anything 
currently there (unless they are overwritten by the restore), but I don't 
have a small restore set to test with at the moment.
