Could you give some more detail?  First, what version of Amanda?  Second,
did Amanda go through all six tapes?  The way you have it set up above,
assuming one tape per day, it should have used the first five tapes
in the first week, then used the sixth tape at the start of the second
week, and only then gone back to the first tape (on the second day of
the second week).

Were there really only five entries on a line?  When I run it, I get
the same number of entries as tapecycle is set to.

What happens if you run "amadmin <config> find <host> </partition>"?

That's clearly bad and it should not have happened.

The general suggestion is that you have at least twice as many tapes
as your dumpcycle.  That way, even if the most recent level 0 is bad,
you have at least one more you can fall back on.
