I’ve heard the notion that a backup you don’t regularly restore is mostly just theater. If you need to feel comfortable that you can restore your backups, then do that. You will need another machine to use, and then just go through the motions.

As in a traincar with a staircase inside, or as in two stacked rail tracks in parellel along a subway route?

Please, could someone disect this frog for me?

I found a Wikipedia article that expands on motivations for the design: Titulus_(fortification)

The description in the wiki article and the orientation of the diagrams on page 63 of the Keeley document convince me that the more common arrangement was to place the detatched screening wall segment on the exterior of the curtain with an interior version sometimes used either instead of or in addition to the exterior screen.

Edit: I think I read the pg63 diagram orientations wrong, so I think my point is mostly that it can be either inside or outside, and that this whole PDF is really cool.

My favorite part is that the switch is still in the OFF position.

This would make a fantastic profile picture!
