May not be exactly the info you seek, but in a survey in April 2003, 6 installations reported total disk capacity of client and servers between 2000 and 5000 GB 5 installations reported total data stored on client and servers between 1000 and 4000 GB 3 installations reported the size of their average daily backup was between 300 and 700 GB 4 installations reported the number of client hosts that were backed up was 60 to 70 hosts These represent the highest numbers reported in the survey. There were a number of very large sites that are known users of amanda that chose not to participate in the survey. jon -- Jon H.
