I dont get it, why is deduping at a chunk level important, can't it just take it as a tradeoff and dedupe at the file level, or does that have the same problems? And why exactly is deduping important for a personal use case, bandwidth is relatively cheap.
In any case, while I want security in these systems to avoid mass survey style attacks, I assume anything I put over the wire to be compromised at least potentially. I keep the kind of files that need that level of encryption on encrypted flash drives.
