I have setup Amanda to backup to vtape.  I want to do a full backup once
per week, incremental other days (weekdays only), but keep 1 month of
backups.  I'm a bit confused about how to set this up in amanda.conf.

Would this work?

dumpcycle 1 weeks
runspercycle 5
tapecycle 20 tapes

Will having 20 vtapes mean it does 20 backups?
