I wonder how many thousands of people are paying them to back up stuff they could easily redownload. Great business model if they de-dupe internally.

- kayoone 16y agothey encrypt all data and i dont think it would be wise of them analyzing their clients data for dupes...if somebody would get to know that their business would be gone.
- jodrellblank 16y agoZFS supports encryption with deduplication, and Dropbox does dedupe accross customers (and why not? It's not a human digging through things). http://blogs.sun.com/darren/entry/compress_encrypt_checksum_deduplicate_with http://blogs.sun.com/darren/entry/compress_encrypt_checksum_... - ZFS link
- schumihan 16y agoWhen different customers use different key to encrypt the data, even if the source is the same, the outcome is different. So it is not feasible to do de-duplication across different customers' data, unless all of them use the same key.
- sliverstorm 16y agoIf you're implying they are crazy for doing so, have you ever lost everything and tried to redownload it all? It's a huge timesink, I tell you. As for de-duping, Dropbox does this. When you drop a Windows ISO or the Office installer into your folder, it hashes the file and realizes 'hey we already have this!' and you don't have to upload it.
