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.
