Now here is what I did... 1. identical drives on the same Adaptec 29160 controller 2. Each drive is sliced and formatted the same 3. I ran 'tunefs -n enable' 4. Mounted drive 2 as /mntg Then as root do this: # dump -C 32 -0Lf - /home | ( cd /mntg ; restore xf - ) DUMP: Date of this level 0 dump: Wed Apr 7 16:17:13 2004 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping snapshot of /dev/da0s1g (/home) to standard output DUMP: mapping (Pass I) [regular files] DUMP: Cache 32 MB, blocksize = 65536 DUMP: mapping (Pass II) [directories] DUMP: estimated 282911 tape blocks.
