A very good suggestion. However ... there had to be a "however" eh? I seem to have this unwritten expectation that with ZFS I would get everything that I always had with UFS and SVM without losing a feature. The ufsbackup and ufsrestore command will both do a complete dump of a UFS filesystem plus incrementals and all the metadata also. I lose that with ZFS as the backup technology does not exist yet to backup all the metadata also. Perhaps we need to craft a zfsbackup and zfsrestore command ? -- Dennis Clarke _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
