Thank you. That was very helpful. Here's the text again: "The ciphertext is erasure-coded into N shares distributed across at least H distinct storage servers (the default value for N is 10 and for H is 7) so that it can be recovered from any K of these servers (the default value of K is 3). Therefore only the failure of H-K+1 (with the defaults, 5) servers can make the data unavailable." To foster my understanding, I've tried to visualize what that means: http://dirk-loss.de/tahoe-lafs_nhk-defaults.png Is that interpretation correct?
