Martin,
You can do it by creating 8 one week dumplevels, or by creating 1
eight week dumplevel.  Or, you can can create 1 one week dumplevel,
which will not expire.  This can be exploited by keeping your dump
information in the backup database for a period of 8 weeks.  Then, if
you need to restore from a tape that is 6 weeks old, you still have
that information in the backup db, and you can use the tape(s)
required.
