I'm only aware of these parameters being explained in the amanda.conf man
page....
However, did you find the "amadmin ... bumpsize" command? You can use
it to check the actual effect of the bump* parameters in the config
file, which perhaps will help you get a sense of how they interrelate:
=====
# su backup -c "amadmin TestBackup bumpsize"
Current bump parameters:
bumppercent 20 % - minimum savings (threshold) to bump level 1 -> 2
bumpdays 1 - minimum days at each level
bumpmult 4 - threshold = disk_size * bumppercent *
bumpmult**(level-1)
Bump -> To Threshold
1 -> 2 20.00 %
2 -> 3 80.00 %
3 -> 4 100.00 %
4 -> 5 100.00 %
5 -> 6 100.00 %
6 -> 7 100.00 %
7 -> 8 100.00 %
8 -> 9 100.00 %
