Dumpcycle

The [dumpcycle] tells Amanda when to do a full dump in conjunction with the [runspercycle] parameter. The dumpcycle represents the number of days over which every filesystem will have a full backup. If I want a complete backup of every system every night then my dumpcycle would be 0. Every 7 days would get me a full backup each week.

Runspercycle indicates how many time in the above dumpcycle that the [amdump] program will be executed. If you do a backup every weekday night but wanted a full backup each week then your [dumpcycle] would be 7 and and your [runspercycle] would be 5.
