You can run several backups a day just fine. However
you must not use more tapes than your tapecycle is.
And to be careful and prepared for disaster:
Have always three generations handy. 
I _recommend_ to have at least:

3 * runspercycle * runtapes Tapes. 

man amanda says:
              For  instance,  if dumpcycle is set to 14 days, one
              Amanda run is done every day (Sunday through Satur­
              day),  and  runtapes  is set to one, then tapecycle
              must be at least 15 (14 days * one  run/day  *  one
              tape/run + one tape).

E.g. you are testing with dumpcycle 1 and up to 4 runs a day, you need
5 tapes as _absolute minimum_ (and then you are depending on each
tape!) and 12 for a warm and fuzzy feeling.

Overflowing the tapecycle in just one day is apparently 
not prohibited :-((
