I always recommend keeping File, Job, and Volume retention at the same
value. Otherwise, you'll wonder why you can't restore an individual
file, and you'll come asking on the mailing list, and we'll tell you why
you can't.... etc.
I think you need a 3 month retention to always have two full backups.
Otherwise, you'll risk losing the oldest backup if the newest backup is
delayed for some reason. Consider it N+1 periods.
