Hi, I'd like to retrieve and permanently archive (offline) a full set of archives stored with one particular key using Tarsnap.
These are of course deduplicated at Tarsnap's end. But if I download them one at at time (using something like "tarsnap --list-archives|xargs tarsnap -r ..." for example), it'll cost me a ton of bandwidth - both at my end which is metered, and in Tarsnap's bandwidth charges. I'd like my bandwith bill to be the "Compressed size/(unique data)" figure from --print-stats, not the "Compressed size/All archives" figure. Since the redundancy is there and my client has all the details, is there any way I can take advantage of this? If not, then I am planning to use an us-east-1 EC2 instance so that at least the Tarsnap server<->client bandwidth is in one place. I can then use that machine to deduplicate and then the download to my machine here can at least be efficient. In this case, will I still end up being billed by Tarsnap for the "Compressed size/All archives" figure? Thanks, Robie
