for now you could send snapshots to files and a file hierarchy on a SAM-QFS archive .. then you've got all the feature functionality there to be able to proactively back up the snapshots and possibly segment them if they're big enough (non-shared-qfs - might make sense if you've got multiple drives you want to take advantage of) .. I believe the goal is to provide this sort of functionality through a DMAPI HSM with ADM at some point in the near future: http://opensolaris.org/os/project/adm/ --- .je _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
