Amanda decides *what* data are being backuped at each
run (ie: this DLE is full-backup, this other one is incremental level 1,...).
But the runs themself are scheduled via cron.
But that's standard Amanda configuration. In your
case, you don't need to care since you will be doing full backups only
(on sunday).

Yes, probably, one has to adjust tapecycle when adding a tape with amlabel.
Also, I don't think modifying runtapes would break
Amanda...
