Nobody should turn on dedup; people who think they are experimenting should definitely not turn on dedup; only people who have a completely sacrificial system and a good knowledge of the data to be stored should consider dedup. > - Consider getting a NAS or an entry-level server. A Raspberry Pi with two disks *is* a NAS or an entry-level server. It's not an awesome one, but it is certainly a cheap one and useful for many purposes. -dsr-
