PS:

I Like reason ( I don't care what anybody does as long as there is a reason behind it - preferably one which make sense, but where I work., people get fired for having no reasons)

"This choice was made because a) most drive failures are transient (eg a new drive can be swapped in relatively quickly) and b) since replicating data out can place a higher burden on other storage nodes, an errant automatic ring update could have cascading failures throughout the cluster."

Makes perfect sense to me. And also cements my idea that nothing really changes without a ring update - operator healing. Which also makes sense to me.

What I am interested in is the effects of recovering from a failure. I think, looking at things, that if I lost all my storage node OS drives to "an attack" as long as I have my proxy alive (or all but one OS drive containing the ring files), it knows where everything is I can build OS node drives of the same IP as before and things would start to function as before pointing at their current storage drives... I do NOT want a situation where I have data, 100+'s of drives of data which I cannot access. Best practice SQLlite backups for a swift deployment ? If not around we need to try and work this.
