Just as an aside, having your backup disks on the same controller as your real data seems a bit risky to me -- what if the controller goes? What if it takes multiple disks with it? > as assigning spindle #s goes I don't quite understand why I would set > that.

Here is my email log from the backup That's correct. maxdumps (dumps per host at a time) defaults to 1. inparallel controls total number of backups at once. > Total Full Daily > -------- -------- -------- > Estimate Time (hrs:min) 7:30 As Frank pointed out, this is a big part of your problem. What OS and FS are we talking here, and what backup program?
