Xz format inadequate for long-term archiving


Interesting read. From my perspective, I tried xz to compress some game isos (that were probably encyrpted themselves, I dunno) and found it took a long time to do not very much, sometimes taking a little off the total size but often adding quite a lot. So instead I just spent a few quid on a bigger hard disc rather than trying to waste cycles compressing stuff.
 
I like to store stories (fanfiction, gutenberg) and the xz compression is quite good (I thought it a fork of 7z). Never had "problems"... but stuff can go wrong, and wow... I never knew bzip2 was that good...and xz that bad
