NLO files are cleaned up (deleted) by the DAOS Prune process that is scheduled to run nightly at 2:00 AM. NLO files are only REMOVED when the DAOS catalog is in a 'Synchronized' state, the NLO refcount is zero, and the NLO was MARKED deleted longer than the prune interval ago. 

You can ALSO run Prune from the console with the COMMAND 'tell daosmgr prune prune interval'. An interval of zero will cause all NLO files with a refcount of zero to be deleted immediately. USE caution when here as you could potentially delete attachments that have never been backed up.
