The short version is, you can't. You can *mark jobs as deleted* in a volume, but that won't free any space. You can delete only the entire volume at one time. You can't compact it except by copying the jobs you don't want to delete to a new volume, then deleting the original volume. And if your disk volumes are hitting 300GB, then each of those copy operations is going to be tying up half a terabyte while it runs. In my opinion, you're going about it all wrong. On disk, you don't have a minimum efficient volume size, and that means you want your volumes SMALLER, not bigger. Your plan should be based on using each volume *only once*. If you're running hourly differential backups, then start a new autolabelled volume for each batch of jobs, with a volume use duration of, say, 59 minutes. When the use duration expires, the next batch of jobs will automatically create a new volume. As soon as a batch of jobs "ages out", you can purge them and delete the volume that contains them. Plus, now you're deleting 5GB, 10GB, 15GB volumes at a time instead of 300GB volumes. I've been running this model for years for my incremental and differential backups, and it works. -- Phil Stracchino Babylon Communications ph...@caerllewys.net p...@co.ordinate.org Landline: 603.293.8485 ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
