With a snapshotting filesystem and/or volume manager, of course.

See above. I believe recent versions of LVM support snapshotting,
although I haven't played with it yet. If you've got big bucks to
throw around, and you're on an IA32 Linux box, then you could look
at Veritas Foundation Suite, which handles snapshotting (though
they call it PIC -- point in time copies).
