I would not consider using dedup in the current state of the code. I hear too many horror stories. Also, why do you think you'd get much benefit? It takes pretty big blocks of exact bit-for-bit duplication to actually trigger the code, and you're not going to find them in compressed image (including motion picture / video) or audio files, for example (the main things that take up much space on most home servers). -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
