We need _some_ backup format that will preserve ZFS ACLs. star doesn't (yet), nor does any other version of tar that I know of. Sun's cpio didn't use to (I haven't tested it recently, anyone know for sure?), and if it does now, it's still cpio *shudder*. Even rsync doesn't support ZFS ACLs (yet). It would be _really_ nice if someone familiar with the rather badly documented ZFS ACL APIs would contribute code to give us some working options. I suspect star and rsync are the least work, as they already have ACL frameworks. And if Sun's cpio doesn't have ZFS ACL support yet, that really needs to happen. I actually took a look at doing this for rsync, but I didn't have enough time to learn the API by trial-and-error. -- Carson _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
