I'm planning to try out deduplication in the near future, but started wondering if I can prepare for it on my servers. one thing which struck me was that I should change the checksum algorithm to sha256 as soon as possible. but I wonder -- is that sufficient? will the dedup code know about old blocks when I store new data?
let's say I have an existing file img0.jpg. I turn on dedup, and copy it twice, to img0a.jpg and img0b.jpg. will all three files refer to the same block(s), or will only img0a and img0b share blocks? -- Kjetil T.
