Set the reserve on the holding disk, if you've got a ton, to something like 30%, which will let it do fulls till there is only 30% of the holding disk left. >> In general, we only need one LTO1 a day, this particular DLE is a >> freak statistic well outside the standard deviations of the other >> DLE sizes, so doing a flush once every cycle is more appealing >> than allocating two tapes per run.
