I just replaced an important session by accident; hence the name. In similar rare occasions - usually I at least see a back-up of that session from recently; but now I don't see any back-ups of this session; even though I've set Session-Manager to back-up sessions which are replaced - automatically. I guess that doesn't include sessions which I close, or replaced closed sessions.

So can I do something to recover this session? Or at least can I set the option - to back-up sessions which I close\replace?
