Amanda (http://amanda.zmanda.com) is an open source network backup and recovery software. I have added a white paper to the lustre wiki (http://wiki.lustre.org/index.php?title=Main_Page#Community_Development_Projects). Look for "Backup: Amanda and Lustre". This paper discusses how to use Amanda to backup Lustre file systems. If you have comments, please send them to me or discuss it in this list. thanks, Paddy -- Amanda http://amanda.zmanda.com ZRM for MySQL http://www.zmanda.com/backup-mysql.html
