How is it different to backup a pool, versus to backup all the zfs filesystems in a pool? Obviously, dd is not viable for most situations as a backup tool... Is there any reason anyone would ever do it for ZFS, aside from forensics? Oh, I know one difference. "dd" to backup the pool would also preserve all the zfs snaps. But if you want, you could have done that with "zfs send" too. So my question still stands: What can you backup in a zpool, using dd, that you can't backup via "zfs send?" (As pointless as this may be, it's academic.) ;-) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
