In summary:

- Crontab will invoke amdump <config-name>
- Amanda knows min. frequency of full backups needed and how many times amdump 
will be run from amanda.conf file
- The clients/files to be backed up are specified in disklist (could be more 
than one)

- Amanda ensures min. freq. of full backup is respected for all disklist entries, however not all backups taken during a particular amdump run would be of same type (full / incremental)

Again, as mentioned in my last post, I am not sure whether dumpcycle is the 
min. frequency of full backup or is it the frequency of full backup?

It is the frequency of when a full backup is done.

It is not the minimum frequency.
When needed, Amanda schedules a backup sooner than the dumpcyle parameter,
e.g. to avoid doing a whole lot of full dumps on the same day in the future.

And neither is it the absolute maximum frequency.
And, it can also happen (but Amanda warns about this in the report)
that a full backup is postponed beyond the dumpcycle frequency, e.g.
when the amount of data would exceed the tape capacity.
