What I mean is, if two clients of a provider upload the same data, do the hosts identify the match and create only references to the identical data for the multiple clients, or do they simply have two copies of the same data on their server?
Caveat: I am merely geeky.
What prompted the thought was an article maybe on /. that Russia might run out of data storage, and this would impact entertainment providers. Seems a good way to save space if that's an issue.
I would guess not, as storage is pretty cheap these days (or was at least in the before times), and it would raise privacy and possibly copyright issues. But a semi-scrupulous and miserly provider might consider it I suppose. Anyone here have any insights or knowledges?
