I have a configuration that do full backup every day.
Yesterday, amanda say that "dumps way too big must skip incremental dumps".
But the tape is used only by 68%, as i can see from the report.

-----------------------
USAGE BY TAPE:
  Label          Time      Size      %    Nb
  bk01       3:29   70593.6   68.0     6
-----------------------

Why amanda can't do full backup? How can i return to make full backup?
In addiction, the amount of data is less than other days, when tape is used by 88%. That's strange...

Sorry for my bad english and thanks for your help.
