I am New to Amanda, While working with amanda found that Amanda is overwriting on the tape which is the biggest drawback for me cause I am using tape library, and one tape haping capacity of 6.25 TB and my Full backup is of 1 TB, How can I maintain it week wise so that I have every week data with me as a full backup so that if want to restore my data from the full backup of 3 years back of a very specific date made possible.

Please guide me on this.
Eagerly waiting for the reply!!
