Thank your for the help.

The tapecycle parameter is active und set to 14. 
But how could I create more tapes?

I created the first tape with "amlabel DailySet1 DailySet100" now I tried to
create another tape with "amlabel DailySet1 DailySet101" but then the
following error message comes: 

rewinding, reading label DailySet100, tape is active
rewinding
tape not labelled

What must I do to create more tapes?

Hope you can help me?!

Thank you!

Amanda works on the assumption that you have many/several/more-than-one
tape that will be used for backups.  It cycles through those tapes,
using one or more for each amdump run.  You specify the "minimum"
number of tapes in the cycle with the "tapecycle" parameter.  Each
tape must be uniquely labeled with the amlabel command before use.
