I'm a bit skeptical about how much deduplication saves them. I have a couple of 100 gigs on ACD, unencrypted, most being family photos/videos - I don't think they're going to find any portion of those that's remotely common to other users - at least, I hope not!
- FroshKiller 9y agoIf it's file-level deduplication, sure. But if it's chunk-level, I think you may find that you actually have many chunks identical to many other users' chunks.
- nimrody 9y agoUnlikely given any non-negligible chunk size and accounting for the randomization effect of compression (image and video). I think deduplication buys them most when people upload common assets - videos downloaded from the net, ebooks, ISO images, etc.
- FroshKiller 9y agoDoesn't compression generally reduce entropy?
