Uhm...Yes it does...

Just after the STATISTICS section you should have (by default):

USAGE BY TAPE:
 Label        Time      Size      %    Nb
 CDO801       2:18 34005742k   99.4   546
 CDO798       1:33 27109731k   79.2    17


That'll list the total it got onto the tape.

Hello,

Is there a way to have the total tape usage in Amanda report?

It happens that sometime Amanda runs out of tape after 50 GB (which is
normal for a 50GB SLR100 tape) but sometime only after 8GB which
clearly means there is a problem. But Amanda reports do not show any
total and I have to compute it by hand to see when there is a problem
and when there is not.

Best regards,

Olivier
