I was thinking on doing this on the filesystem level and lazy when the server was not busy. I would like to see in linux what has been available for 10+ years with ntfs the ability to turn on compression on a per file basis at any time. There are several options for doing filesystem compression under linux but most of these are experimental. I have not spent much more thought about this because I mainly use tape for backup at work. At home I do use disk but that happens at 3AM and hopefully I am not still using the machine at that time..
