comment Blowfish in CBC mode with multi-use keys. Is the 64-bit blocksize a fatal issue if one were to encrypt TBs of data?
Also, according to wikipedia: "Blowfish. Blowfish's weak keys produce bad S-boxes, since Blowfish's S-boxes are key-dependent. There is a chosen plaintext attack against a reduced-round variant of Blowfish that is made easier by the use of weak keys. This is not a concern for full 16-round Blowfish." So, I think that answers my question regarding the reflection attack? Please someone correct me if I'm wrong.

I think I may have found the answer to my main question here: crypto.stackexchange.com/a/1106/7298. And basically I'm gathering this means that when encrypting TBs of data there is a very high chance of some plaintext leaks, but only 8 bytes here and there? So it probably wouldn't actually matter. Another thing is... since Crashplan uses data de-duplication, would this mean that this actually might not be an issue whatsoever as it won't be encrypting the same data twice ever?
