yes, and I appreciate the simplicity of simply plugging in the drive and
everything happening automatically. *But* we are speaking of administrative
operations here, not a fancy end-user interface. There's always the chance
you want to plug in the (correct, recognized) drive for a different reason,
such as checking its SMART status, copying the image, accessing a previous
version of your BackupPC pool, reading the serial number or because you got
drives confused and think it's your transportable photo collection. Chances
are, you shouldn't be doing that on the BackupPC server. Chances are, you
should be aware of what will happen. But still: extensive, potentially
destructive operations happening automatically without a chance of user
interaction is something that belongs in the world of Windoze. Linux is
becoming more like that fast enough already, so I won't let this chance pass
to argument against it :-).

Of course there's also the chance of you simply plugging the drive in at an
inappropriate moment, when you wouldn't want the sync to happen. You might
notice it when logging in to call the script to start the sync, but you won't
log in just to check, if you went to the trouble of automating the sync in the
first place, will you?

Just because you *can* automate something, that doesn't necessarily mean it's
a good idea to do it. Then again, under some circumstances it may well be.

Regards,
Holger
