Xz format inadequate for long-term archiving (2017)
Are these concerns, about error recovery, outdated? If I want to recover a corrupted file, I find another copy. I don&#x27;t fiddle with the internal length field to fix framing issues. Certainly, if I want to detect corruption, I use a sha256 of the entire file. If that fails, I don&#x27;t waste time trying to find the bad bit.<p>To add to that, if you need parity to recover from errors, you need to calculate how much based on your storage medium durability and projected life span. It&#x27;s not the file format&#x27;s concern. The xz crc should be irrelevant.
