Volume allocation rules

You can move files from one volume to another using allocation rules. Use the move_volume_files utility with the -rulesfile argument to retrieve an XML file containing the volume allocation rules template, edit the rules as desired, and then use the utility to move the volume files. You can write volume allocation rules based on various dataset, item, item revision, and volume criteria. Example Consider a site using both CAD and JT files. Because JT files are volatile and can be recovered from the CAD file if lost, they are on a different backup schedule. The administrator decides to store all JT files in a different volume than the CAD files. Rules can be written in the XML file specifying different target volumes for the JT and CAD files. Each time the utility is run, JT and CAD files not already stored in the respective target volume are moved to the appropriate destination. The utility can be run manually, as a cron job, or as a scheduled task. The volume allocation rules accept the following criteria.
