Why doesn't amanda use as much tape as I am giving it?  I have amanda
configured to use two tape drives ( AIT SDX1-25C tapes ).  My tapetype
states that the tapes are 24192 Mb in size.  It filled the first tape
and used only used 8+ Gb of the second.  Does amanda ever promote dump
levels or only demote them to reduce the dump size?
