I haven't used ZFS yet, but if stuff is put there in 'file' with an inode for each, I wonder if dump/restore would actually work on ZFS. Of course, it would not preserve the formatting/filesystem building. But it doesn't do that fur UFS either. Backups created by dump and read by restore are just files with a series of files as they come from disk organized and located by inode. But, as I say, I haven't worked with ZFS yet so do not know how date is kept track of on ZFS. ////jerry > > So, my question is this: Can someone point me to the proper place to > start reading on getting RELENG_8+zfs backed up to "tape robotics" (or > more specifically: LTO-3 with a HP autoloader)?
