It copies the specified directory structure to another disc, in a yyy/mm/dd folder. However it's intelligent enough to spot that the file it's doing now is the same as the copy it did yesterday and just create a link to it instead; net result is you don't eat up disc space for files that don't alter. no compression, and it copies the whole file again if you change just one byte, but it's *very* easy to get back old files - just cd to the right place and cp it out. With disc prices as they are, I just bought a cheap IDE 120Gb to do my backups onto... Hope that helps, Rob, > APH Computers Ltd.
