Since tar doesn't really have the same concept of levels, Amanda fakes it by writing similar information in /etc/amandates. Neither one has any idea of multiple configs, so the same file will get updated each time you run any of your configs. So when your 'weekly full' runs it will update the file, and then when your 'daily' runs, it will be expecting to back up files newer than the last 'daily' run, but dump or tar look for files newer than the times in the dumpdates/amandate file and will only be backing up files newer than the time of the 'weekly' run. The end result is that your daily set of tape may be unable to restore the entire filesystem. Your weekly set should be OK since its always a full.
