Data retention refers to how many data extracts should be kept on DataTap.
- Retain all: default setting, all fetched extracts are kept unless manually deleted
- Retain N extracts: only N extracts are kept
- Retain N fetches: only N fetches are kept. A fetch is a collection of one or multiple extracts with the same scheduled date
- Retain N days: only extracts generated within the last N days are kept
N + 1 = number of extracts/fetches/days kept. If N=5, 6 are retained etc.
