It is also possible to configure independent replication factor per distinct `vmstorage` groups - see [these docs](#vmstorage-groups-at-vmselect).
`vmselect` doesn't serve partial responses for API handlers returning raw datapoints - [`/api/v1/export*` endpoints](https://docs.victoriametrics.com/#how-to-export-time-series), since users usually expect this data is always complete.
`vmselect` doesn't serve partial responses for API handlers returning [raw datapoints](https://docs.victoriametrics.com/keyconcepts/#raw-samples),
since users usually expect this data is always complete. The following handlers return raw samples:
- [`/api/v1/export*` endpoints](https://docs.victoriametrics.com/#how-to-export-time-series)
- [`/api/v1/query`](https://docs.victoriametrics.com/url-examples/#apiv1query) when the `query` contains [series selector](https://docs.victoriametrics.com/keyconcepts/#filtering)
ending with some duration in square brackets. For example, `/api/v1/query?query=up[1h]&time=2024-01-02T03:00:00Z`.
This query returns [raw samples](https://docs.victoriametrics.com/keyconcepts/#raw-samples) for [time series](https://docs.victoriametrics.com/keyconcepts/#time-series)
with the `up` name on the time range `(2024-01-02T02:00:00 .. 2024-01-02T03:00:00]`. See [this article](https://valyala.medium.com/analyzing-prometheus-data-with-external-tools-5f3e5e147639)
for details.
Data replication can be used for increasing storage durability. See [these docs](#replication-and-data-safety) for details.
