This is the closest method Amanda has to spanning one partition or filesystem over multiple tapes, correct? If I have two 40GB tape drives and an 80GB partition which I want to backup using dump and not GNU tar, I can use the RAIT code w/o parity to span the partition over the two smaller tapes? If so, how do I configure to toss the parity away if I only have two tape drives? If it's similar to RAID 3 then I can just specify the third drive as /dev/null? > Otherwise you can just run two amdumps, and have each one do roughly > half of your data. > But this won't span a large partition over smaller drives. > ----- > Marc Mengel <[EMAIL PROTECTED]> > -- C.
