wouldn't deduplicating encrypted data still work but your hit rate would just be a lot lower. you would have to work on a block instead of a file level but in theory you could dedupe file blocks that had been encrypted, because either way in the end its just bits.
Or is the assumption that with encrypted data you are so incredibly unlikely to see hits that its not worth doing...
- esutton 15y agoif a file is encrypted correctly, you should not be able to compress it or match it to the same file encrypted a second time.
- lukesandberg 15y agoI understand that, but couldn't two different files encrypted with two different keys theoretically share some identical blocks. Obviously this is way less likely than two unencrypted files sharing blocks but still it could happen.
