Several startups have emerged over the past few years based on this idea of 'data deduplication', and some have been swallowed up by bigger fish that clearly think it's promising. But almost all such efforts have focused on backup/archive data rather than on primary disk storage - the only example of the latter that I've noticed is that NetApp started supporting deduplication for primary disk storage about 6 months ago. - bill This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
