I’ve been reading the docs and the list for a while but I still got this question:
I have the Conf{FullKeepCnt} = 2; but I do weekly backup and daily incremental and this has been going for about a month without any problems.
Q1) I have 4 Full and many incremental, but the FullKeepCnt is set to 2.
According to blow, I guess I am ok since the first Full is not gonna be deleted until 10, 11 and 12 are expired.
Thus, I could just set the Conf{FullKeepCnt} = 1 or any number. So why do we even need to change the FullKeepCnt setting?
(I am using rsync so the space consumption doesn’t seem to be an issue)
