Both can be configured to do a differential backup of the changed files or a full backup. I use mondorescue on my workstation to make certain that if a drive fails it can be recovered from bare bones in the time taken for the restore. Mondo is run from a crontab entry and takes care of itself by writing CD/DVD images that can be then put onto the actual DVD when I choose. HTH Jeff
