    Dedupe rocks, in theory. However you can't dedupe encrypted datasets, which has humbugged the technology because all data will be encrypted everywhere before too long. And don't use dedupe as a backup target - it depends on one physical copy and many logical copies, so your backup generations might well end up depending on the same physical data blocks. With tape you have many physical copies and therein lies safety.

    Dedupe ratios and bias

    Since the article mentions my blog post, I guess its time to chime in! Pure Storage claims typical savings rates of around 6:1 based on actual data collected from their customers. I believe the numbers. I've seen similar stats coming in from Permabit's OEM partners. Note that these savings don't just come from dedupe, but also from compression and pattern elimination. All three are features supported by Pure Storage as well as by Permabit's OEMs.

    For reference:

    I explain how I determined the maximum potential rate for a Pure Storage array here: http://permabit.com/tough-challenges-ahead-for-pure-storage-2/ and I explain how Permabit gets its own performance numbers here: http://permabit.com/vdo-at-one-million-iops-zero-hour-for-tier-zero/
