'dumpcycle' is the number of days (or weeks) in elapsed time that 
amanda has to achieve a level 0 backup of every entry in the 
disklist.
'runspercycle' is how many times amanda will be run in dumpcycle days.
For businesses that have no one to change tapes over the weekends, 
these are often set to 7 and 5 respectively.

If one area, more specifically, one entry in the disklist is larger 
than a tape, it will fail.  amanda cannot span a single disklist 
entry (DLE) across more than 1 tape.

The solution is generally to use tar and an exclude file in the 
dumptype, using a seperate but except for the exclude file otherwise 
identical dumptype, repeat till its small enough to fit.  IMO, better 
yet is to use tar with seperate DLE's for each listing a seperate 
subdir as its starting point.  I have my /usr dirs broken up into 
individual subdirs in this manner here.

Haveing the amount of data broken up into smaller pieces also 
facilitates amandas ability to juggle the schedule and achieve a more 
uniform amount of tape usage per each run, which is also one of her 
targets.
