As far as ZFS is concerned any discussion of how you'll read today's media a decade into the future is completely OT :) "zfs send" as backup is probably not generally acceptable: you can't expect to extract a single file out of it (at least not out of an incremental zfs send), but that's certainly done routinely with ufsdump, tar, cpio, ... Also, why not just punt to NDMP? Nico -- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
