For me I am still waiting for this to happen on the file system level
and when I want it to happen. I mean after the backup jobs are done I
can trigger a cron job to set some attributes on the files causing
them to compress. Windows has had this ability with ntfs for a very
long time and I was amazed that linux did not do that but missing this
feature does not stop me from using linux for all the departments
15TB+ raid storage.
