So you have a backup server in production, that has storage and does a zfs send to removable media, on periodic basis. (I know I do.) So you buy a new server, and it comes with a new version of zfs. Now you can't backup your new server. Or maybe you upgrade some other machine, and now you can't back *it* up. The ability to either downgrade a pool, or send a stream that's compatible with an older version seems pretty obvious, as a missing feature. I will comment on the irony, that right now, there's another thread on this list seeing a lot of attention, regarding how to receive a 'zfs send' data stream on non-ZFS systems. But there is no discussion about receiving on older zfs systems. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
