Surely how well it compresses depends on the material you're backing up
It seems they went all in on the "compressed" value after missing the doubling of the real space in LTO6.
- sebazzz 3y agoEspecially if you backup encrypted data (which isn't unusual - to have data encrypted at rest) you will have a compression ratio of 100% or even more (metadata of the compression needs to be stored too)
- monocasa 3y agoThe drives will do encryption too so that you don't have to pick between encryption at rest and compression.
- sebazzz 3y agoFrom the SSL world we know that encrypting compressed data can lead to vulnerabilities in the encryption. Does that nog apply here? https://en.wikipedia.org/wiki/CRIME?wprov=sfti1 https://en.wikipedia.org/wiki/CRIME?wprov=sfti1
- monocasa 3y agoIt doesn't really apply as both CRIME and BREACH rely on small N on the payload size, and heavy use of repeated chosen plaintexts to iterate through the secret state space.
