I'm not familiar with PostgreSQL database administration , so I figured I might ask for help from someone more knowledgeable on the subject. What would you recommend in order to setup a regular (daily) OpenERP database backup? Ideally, this would be done without stopping the database (hot backup). Is it possible to setup incremental backups, e.g., one weekly reference backup and daily incremental backups? Are there any automation scripts available I might use? (I'm using Ubuntu Server.)
